3.2.4 Purge System
General

When the robot is installed in an area where explosion hazard is present, it is
equipped with a purge system. The purpose of this system is to apply compressed
air in the manipulator. The compressed air is kept at a higher pressure than the
atmospheric pressure and so preventing hazardous gases from entering the
manipulator interior.

3.3 Control Panel Description

3.3 Control Panel Description
Panel Overview

The following gives a description of the control panel switches and indicators.
Mains Power Switch, QS1
Switch for applying mains power to the robot system.

Emergency Stop Button, SB3
Push/pull button for instant stop of the robot regardless of operating mode.
To reactivate emergency stop chain, the button must be released (pulled out
or rotated clockwise), then the Motor On button must be used.
If pressed during a program, operation can not be resumed on the same
object.
Purging OK Indicator, HL1
Indicator lamp informing the user when the purge sequence is completed at
start-up and the robot is ready for operation.
Motor On/Off Switches, SH4/SB5
Used to enable (I) or disable (0) electrical power for the manipulator axis
motors.
The indicator in the ‘on’ button will be lit when power is applied. (Motor ‘on’ is
one of many conditions for applying power).
The Motor On switch is also used to reset the emergency stop chain and to
enable run chain in Manual mode.
Continuous light: Ready for program execution.
Fast flashing light: (4Hz): The robot is not calibrated or revolution counters are
not updated. The motors have been switched on. By fast flashing, call for
service assistance.
Slow flashing light: (1Hz): One of the spray booth safety switches is active.
The motors have been switched ‘off’.
High Voltage On/Off Key Switch, SA7/SB8
Toggle key switch used to switch power for high voltage equipment on (“I”),
and button used to switch power for high voltage equipment off (0).
Toggle key switch means that the switch returns to off position when released,
as indicated by the (“I”) notation.
The switch is only applicable if the robot is fitted with HV controller.

3 System Description
3.3 Control Panel Description

Operating Mode Selector, SA1
Key switch used to lock the robot in one of the following 3 operating modes:
Automatic /
mode: Used for running ready-made programs in
production. Joystick can not be used.
Manual Reduced Speed /
mode: Manual mode for programming and
setup. Max. speed: 250 mm/s (600 inches/min.)
Manual High Speed /
speed.

mode: Manual mode for testing at full program

WARNING:
The Mode Selector is a key type switch, intended to increase personal safety.
When operating within the working area of the robot, the switch shall always
be in Manual mode, and the operator shall keep the key with him so it is not
possible for other persons to take over control of the robot.
IMPORTANT:
In Manual High Speed mode, the System Speed is by default set to a low
value. This is a safety feature to avoid a ‘high speed surprise’ in case the key
switch was set one notch too far when switching to programming mode. The
system speed must be set to 100% manually in order to obtain full speed.
Mode Change Acknowledge
When leaving Manual Reduced Speed mode, an Acknowledge input is
required. If operated from the pendant, a dialog for this purpose is shown. For
systems controlled by a PLC or RobView, there is a Paint Command available
for this purpose.

Procedure

Lifting the cabinet

This procedure describes how to lift and transport the control cabinet.
WARNING! Attach the top of the cabinet to the fork lift using a strap or similar to

prevent it from tipping over by braking etc. See Figure 20, lower left illustration.
1.

After having unloaded the control cabinet crate from the lorry, use a fork lift
and transport the cabinet to the installation site or as close to the site as possible
before removing it from the pallet.

Unpack the supplied packages and check that the content is correct and
undamaged.

Place the cabinet on the floor and remove packing material.

WARNING! Do not walk under the hanging load.

Transport the cabinet to its permanent location using an overhead crane or fork
lift. See Figure 20, lower left and right illustration.

CAUTION! If lifting straps are used, they must be attached to all 4 lifting eyes.

For information on location of the cabinet and information on how to secure the
cabinet to the floor, etc., see ’Cabinet Location’ on page 48.

5.2.3 Cabinet Location
General

The control cabinet may be located at a convenient location outside the spray booth.
The cabinet should be placed in a manner which will provide proper cooling and
give space for entering cables via a cable conduit etc. The cables should be routed
under the cabinet from the back and entered into the cabinet via the bottom front
entrances. The cabinet should, for safety reasons, be secured to the floor using 4 e.a.
10 mm bolts. Access to the control cabinet interior is available from the front.
For information on controller dimensions, weight, footprint, etc, see ’Controller
Specifications’ on page 32.

Temperature
Requirements

To meet the requirements of proper cooling, the cabinet must have a free space of
minimum 10 cm at the back and sides. This is especially important where the
ambient temperature approaches the specified maximum. For temperature higher
than specified maximum, additional cooling device is required.
For information on controller temperature range, see ’Controller Specifications’ on
page 32.

Cooler

For installation of cooler, see ’Cabinet Cooler Installation’ on page 105.

Protection Standard

The cabinet enclosure protects against dust, splashing water and contact with live
parts. Degree of protection rating is IP54 in accordance with EN IEC 60529 and
NEMA 12. Avoid however spraying the control cabinet with water or other liquids.

Vibration and Shock

The control cabinet and its contents can withstand shocks due to the normal
transport in the workshop. If the floor on which the cabinet is to stand permanently
is subject to vibration, the cabinet should be mounted on shock-absorbing vibration
dampers.

Isolation Transformer

If the plant has a history of extreme mains power transients and interference
voltages, an isolation transformer or an interference suppression device should be
installed.

5.2 Component Installation

5.2.4 Purge Unit Installation
General

The purge unit must be installed between the control cabinet and the robot to
provide compressed air inside of the robot to prevent hazardous gases from entering
into the robot interior.
The purge unit is available in a special version, called ‘Purge Unit with Connector
Box’, for use with trolley mounted robots. For installation of this purge unit, see
’Purge Unit w/Connector Box’ on page 111.
Non-ex robots may be supplied with a pressurized junction box substituting the
purge unit. The design of this box is the same as the purge unit, but it includes only
supply pressure on/off valve and maintenance pressure regulator and gauge.

Purge Unit Location

The purge unit must be installed outside the hazardous area, e.g. on the cabin wall
(the cabin wall must be grounded).
The distance from the control cabinet to the purge unit and from the purge unit to
the manipulator must be planned in accordance to the length of the supplied cables.
The cables may be supplied in standard lengths or lengths specified by the customer.
It is recommended to install (locate) the purge unit preliminary and wait with
finding the final position until after the cables have been laid.

Flexible Hose Layout

The flexible hose is normally laid in a cable conduit. The hose is resistant to
solvents.
CAUTION! The flexible hose must not be stretched as this will put strain on the

internal cables which can not be stretched in the same way. If the flexible hose is to
be installed in vertical direction, e.g. where the robot and purge unit are placed on
different floors, the flexible hose MUST be secured with suitable clamps at e.g.
600 mm distance to prevent the weight of the hose to apply strain to the internal
cables.
A flexible hose laying horizontally in a cable conduit does not need to be clamped.

Purge Unit Air
Connection

The purge system must be connected to a clean air supply such as instrument air.
This is important to avoid internal contamination and corrosion. The air connection
must be able to supply approx. 30 m³/h during the purging sequence and 0.3 m³/h
during normal operation (maintenance pressure). The purging sequence time at
start-up is depending on the robot type as noted on the robot identification plate on
the manipulator, see ‘Product Manual, Manipulator’, System Description.
For specification of the purge air, see also ’Purge Unit Specifications’ on page 36.

Product Manual, Control Cabinet IRC5P

5.2 Component Installation

Installation

The purge unit consists of the purge valve assembly and a purge connection. The
purge valve assembly can be mounted on the cabin wall or at another suitable
location, and the purge connector(s) can be placed at a convenient location, either in
the cable conduit or fastened to the cabin wall etc. using a suitable clamp. For
dimensions, see ’Purge Unit Specifications’ on page 36.

5.4.1 Introduction
About this Section

This section describes the function of the robot’s safety chains and includes
information on user connections in the chains.
All connections in the safety system are performed via connectors on the Safety
Connection Board, SCB. For location of the board, see ’Controller Connections
Overview’ on page 42.
WARNING! All connections in the safety system must be performed in accordance

with the following description.

The Safety Chains

The system has 2 safety chains related to the robot as listed below.
• Emergency Stop Chain
• Run Chain
The function and connections in these chains are described in the following.
The system also has safety chains and interlock functions related to the cabin and
process equipment. These chains are described under ’Cabin Safety System
Connections’ on page 78.
Before any connections are made in the safety chains, section ’Safety System
Standards’ on page 65 must be read.

Tightening Torque

All screw connections in the safety system must be tightened in accordance with
’Tightening Torques’ on page 216.

5.4.2 Safety System Standards
General

Normal emergency stop standards require 2 different activities to be performed to
re-establish running mode after an emergency stop situation:
• The activated emergency stop switch must be manually released.
• Power must be re-applied to the robot’s axis motors.

The Safety Chains

There are 2 safety chains in the system; the emergency stop chain and the run chain.
The Emergency Stop Chain includes the main panel emergency stop button, the
pendant emergency stop button and possibly one or more external emergency stop
buttons. All stops are category 0 stops.
The Run Chain includes auto mode stop, test mode stop, general mode stop and
delayed stop. All stops except delayed stop (category 1) are category 0 stops.

Emergency Stop Reset

The emergency stop chain needs a reset signal to be applied after an emergency
stop. If the robot includes a control panel, this reset signal will be applied
automatically when pressing the Motor On button. If the panel is not available, an
external reset signal must be applied after breaking the emergency stop chain before
motor power can be re-applied.
The run chain does not require a reset signal.

Emergency Stop
Category 0

Emergency Stop Category 0 stops the robot by immediate removal of power to the
axis motors and activating the axis brakes. Different types of emergency stop
category 0 are available; External Emergency Stop, General Mode Stop and Auto
Mode Stop. Which type to use must be based on risk analyses for the installation.
WARNING! Emergency Stop Category 0 must not be used as a convenient way to

stop the robot in situations which are not emergency situations. Using emergency
stop category 0 will remove motor power and activate the axis brakes instantly,
causing unnecessary wear of the brake disks (depending on the speed of the robot
when the stop occurs).
Note: The axis brakes are primarily designed for holding the robot in position when

idle. The brakes are certified for 300 stops performed with category 0 stop before
worn to an extent where they can no longer hold the robot in position.
Important: Warranty claim will not be accepted for a damaged motor if the failure is

caused by excessively worn brake.

Emergency Stop
Category 1

Emergency Stop Category 1 is a controlled stop function which will allow the robot
control system to stop the motion of the robot while the robot is running in the

Product Manual, Control Cabinet IRC5P

3HNA009834-001 en Rev.06

5 Installation and Commissioning
5.4 Robot Safety System Connections

programmed path. After a category 1 stop (Delayed Stop), the robot can be restarted and operation resumed after the cause for the emergency stop has been
removed. Stopping the robot by category 1 stop will cause the robot to stop
immediately using electrical power to brake and stop the motor speed and then
remove power and apply brakes after 2 seconds.
WARNING! Emergency stop category 1 must not be used as a convenient substitute

for emergency stop category 0 where emergency stop directly involves people
getting in contact with the robot and conveyor operation.

Stop Time

Switch Type

The time for the robot to stop after an emergency stop category 0 are as shown in the
table below. Note that the indicated times are dependent on the weight of the
application equipment mounted on the robot.
Speed

Stop time

500 mm/s

80 ms

1000 mm/s

100 ms

1500 mm/s

120 ms

Connections for the emergency stop system in the robot emergency stop chain will
fulfil these requirements, provided that the correct types of switches are used. These
switches must be as follows:
• Switches used for Emergency Stop, General Mode Stop and Auto Mode Stop
must be of positive opening contact type according EN IEC 60204-1 and
EN IEC 60947-5-1. Additionally installed External Emergency Stop switch(es)
must be of a type which will be locked after operated, and re-opened by pulling /
rotating the switch knob.
• Any connections or use of switch types not complying with the description and
diagrams in this manual that will corrupt the function of the emergency stop
system will be the full responsibility of the user.

Dual Safety Chains

The emergency stop-, run-, motor-, enabling device- and process (cabin interlock)
chains operate in a dual chain system, Chain 1 and Chain 2. Both chains must be
activated in order to obtain robot motion state.

Chain Monitoring

The dual safety chains are monitored by software and hardware. If one of the chains
does not activate within a time T after the other chain is activated, an error will
occur. In this system, the time T is equal to 2 seconds.

Stop function. For information on this connection, see section ’General Mode
Stop (Category 0)’ on page 74, alternatively ’Delayed Stop (Category 1)’ on
page 74.

If required, install External Emergency Stop Reset Button(s) or connect reset
input to the plants emergency stop system controller. For information on these
connections, see section ’Emergency Stop Reset’ on page 70.

If required, implement an Extra Enabling Device in addition to the enabling
device on the pendant. For information, see section ’Test Mode Stop

5.4.4 Emergency Stop Chain
General

The emergency stop (emy stop) chain is a dual channel chain where all switches and
relay contacts in the chain must be closed to enable power to be applied to the axis
motors. Breaking the emergency stop chain will cause electric power to be removed
from the robot axis motors and activate the axis brakes (breaking the run chain).
Breaking the chain will also disable the paint system, switch off high voltage and
stop pump motors, etc. After having stopped the robot by breaking the emergency
stop chain, it is required that the emergency stop button is manually pulled out and
that emergency stop reset is activated before power can be re-applied to the robot.
The two chains are called Chain 1 (Ch1) and Chain 2 (Ch2).
A principle diagram of the run chain is shown in Figure 31.

Emergency Stop Chain
Supply

The emergency stop chain 1 and 2 are supplied by the internal +24VDC in the
control cabinet.
The chain can also be supplied by an external +24VDC supply. The emergency stop
chain in the robot system will then be active also when the control cabinet main
switch is switched ‘off’. This function may be desired if the robot emergency stop
system is connected in the plant emergency stop system.
• External power for the emergency stop chain can be connected to connections
marked ‘Ext Emy Stop Chain Supply’ in connector SCB-X4 pin 1-2 as shown in
Figure 29 and in principle diagram in Figure 31.

External Emergency
Stop (Category 0)

This is a connection where the user may implement one or more normally closed
(positive opening) switches in the robot’s emergency stop chain. This connection is
normally used in single robot installations. In more complex installations, the
General Mode Stop (category 0) or Delayed Stop (Category 1) function is normally
used. Which type to use must be based on risk analyses for the installation.
• To install Emergency Stop switch(es), remove 2 jumpers (for chain 1 and 2) and
install a 2 pole, normally closed switch at terminals marked ‘Emergency Stop’ in
connector SCB-X1 pin 1-4 as shown in Figure 29 and in principle diagram in
Figure 31. The switch must comply with ’Safety System Standards’ on page 65.

Emergency Stop Reset

The emergency stop chain must be reset after the chain has been broken. To reset the
system, the cause for the emergency stop must first be removed and then a reset
signal must be applied.
An emergency stop reset signal is automatically applied when pressing the Motor
On button on the control panel, but the signal may also be applied from an external
PLC or reset switch. The emergency stop reset signal is also used to send an
acknowledge signal to various internal and external systems.

• To connect an external ‘Emergency Stop Reset’ signal, install a normally open
switch at terminals marked ‘Emergency Stop Reset’ in connector SCB-X13 pin
1-2 as shown in Figure 29 and in principle diagram in Figure 31.
Important: The emergency stop reset signal is part of the safety system and has for

this reason a time limit of max. 2.5 seconds. The length of the reset signal must for
this reason not exceed this limit. If exceeded, the enable chain will shut down.

Emergency Stop
Feedback

The external emergency stop feedback connections (chain 1 and chain 2) can be
used to implement the robot’s emergency stop chains into the plant emergency stop
chain. An emergency stop in the robot can thereby be used to activate the plant
emergency stop. The relay switches to be used for this purpose are galvanically
isolated from the rest of the emergency stop chain in the robot. The switches are
closed when the robot emergency stop chains in the robot are OK.
• To include the robot’s emergency stop chain in an external chain, connect the
external chain at terminals marked ‘Emergency Stop Feedback’ (for chain 1 and
2) in connector SCB-X2 pin 9-12 as shown in Figure 29 and in principle diagram
in Figure 31. Supply voltage should be 24VDC, max 500mA. The external chain
connection must be non-capacitive.
WARNING! To avoid damage to the internal emergency stop chain in the IRC5P

controller and thereby violate the safety system, the customer must provide
individual monitoring of safety chain 1 and 2 and current limiting at 500mA in the
external chain.

5.4.5 Run Chain
General

The run chain is a dual channel chain where all switches must be closed to be able to
run the robot. Breaking the run chain will remove electric power from the robot axis
motors. By closing the run chain, power will be re-applied to the motors, and
operation can continue. The function of the run chain is depending on the position
of the Mode Selector on the main control panel. This section describes the
connections that can be made in the run chain.
A principle diagram of the run chain is shown in Figure 32.

Mode Selection

Test modes, Manual Reduced Speed /
- Manual High Speed /
and
Automatic /
mode, are operating modes selected by the mode selector key
switch on the main panel, and are part of the total safety concept for the robot
installation. The three operating modes are as follows:
Automatic mode: Used to run the robot in production.
Manual Reduced Used for program teach and program optimizing purpose. Maximum
Speed mode:
robot speed is restricted to 250 mm/sec.
Manual High
Speed Mode:

Used to run the program for test and program optimizing. Robot may
be running at full speed (no optimizing operations that can change the
path of the robot can be performed).

CAUTION! The key in the mode selector must be brought to the operating site

together with the pendant to avoid another person from accidentally changing the
operating mode for the robot.

Auto Mode Stop
(Category 0)

Operating the Auto Mode Stop function will remove power from the robot when the
mode selector is in Automatic mode. Typical use of this function is as safety switch
for the spray booth entrance door to allow for a person to enter the spray booth for
test or programming when the robot is in Manual Reduced / High Speed mode. If
the spray booth has more entrances, switches must be installed in series for all
entrances. Light grid / switches must also be installed at the conveyor entrance / exit
etc.
• To install the Auto Mode Stop switch, install a 2 pole switch at terminals marked
‘Auto Mode Stop’ (for chain 1 and 2) in connector SCB-X1 pin 5-8 as shown in
Figure 29 and in principle diagram in Figure 32. The switch must be of a type
which will be closed when activated (spray booth door closed etc.). The switch
must comply with ’Safety System Standards’ on page 65.
Note: To prevent running the robot without paying attention to the auto mode stop

switch, the robot is shipped without jumper installed in this position.

Product Manual, Control Cabinet IRC5P

5 Installation and Commissioning
5.4 Robot Safety System Connections
WARNING! It is the full responsibility of the user to make sure that all entrances to

the working area of the robot are protected by Auto Mode Stop switches. This is
essential to prevent personnel from entering the working area of the robot while the
robot is in operating mode (Auto).

General Mode Stop
(Category 0)

Operating General Mode Stop will stop the robot and remove electric power from
the axis motors the same way as when breaking the emergency stop chain. The
difference between using the emergency stop and the general mode stop function is
that reset signal is not required to reset the stop condition. Power must be re-applied
to the axis motors by activating Motor On on the main panel or from an external
panel or PLC.
The General Mode Stop function is normally used in more complex installations
where the robot emergency stop system is integrated with the factory emergency
stop system.
• To install the General Mode Stop function, remove two jumpers (for chain 1 and
2) and install a 2 pole switch at terminals marked ‘General Mode Stop’ in
connector SCB-X2 pin 1-4 as shown in Figure 29 and in principle diagram in
Figure 32. The switch must be of a type which will be closed when activated.
The switch must comply with ’Safety System Standards’ on page 65.

Delayed Stop
(Category 1)

Delayed Stop is a Category 1 stop, and is a controlled stop function which will
allow the robot control system to stop the motion of the robot while the robot is
running in the programmed path. After a category 1 stop, the robot can be re-started
and operation resumed after the cause for the stop has been removed. Stopping the
robot by category 1 stop will cause the robot to stop immediately and power to be
removed after 2 seconds.
Delayed Stop is typically used to protect entrance doors located at a distance from
the robot and conveyor or used in conjunction with plant emergency stops not
directly involving the robot operation.
WARNING! Emergency Stop Category 1 (delayed stop) must not be used as a

convenient substitute for emergency stop category 0 (general mode stop) where
emergency stop directly involves people getting in contact with the robot and
conveyor operation.
• To install the Delayed Stop function, remove two jumpers (for chain 1 and 2) and
install a 2 pole switch at terminals marked ‘Delayed Stop’ in connector SCB-X2
pin 5-8 as shown in Figure 29 and in principle diagram in Figure 32. The switch
must be of a type which will be closed when activated (spray booth door closed
etc.). The switch must comply with ’Safety System Standards’ on page 65.

Test Mode Stop
Category 0)

The test mode stop may be used to implement an enabling device in series with the
enabling device on the pendant. If used, both this enabling device and the enabling
device on the pendant must be operated to be able to apply power to the axis motors.
The enabling device function is only functioning in Manual Reduced Speed /
mode and Manual High Speed /
mode. The extra enabling device may be used
as an extra safety function during programming and test. The device must be
designed in the same way as the device on the pendant, i.e. the handle must be held
in center position to be activated. Releasing the device or pressing too hard will
operate the stop function.
• To install the extra enabling device, remove two jumpers (for chain 1 and 2) and
install a 2 pole switch at terminals marked ‘Test Mode Stop’ in connector
SCB-X1 pin 9-12 as shown in Figure 29 and in principle diagram in Figure 32.
The switch must be of a type which will open when not activated (released or
pressed too hard). The switch must comply with ’Safety System Standards’ on
page 65.
The enabling device must comply with EN ISO 10218-1, 6.4.6.
Important: These connection points are not Ex protected. If used in a hazardous

area, the enabling device must fulfill the requirements for such use.

Hardware Motor On

Hardware Motor-on is the signal which will apply power to the robot when all
conditions for starting the robot are correct. In Automatic /
mode, the signal is
applied by pressing the motor-on button on the main control panel, but the signal
may also be applied from an external control desk or PLC etc. In Manual Reduced
Speed /
mode and Manual High Speed /
mode, the motor-on signal is
applied by activating the enabling device on the pendant. The power will remain
‘on’ until the enabling device is released or pressed too hard.

Software Motor On

The software motor-on function is used to apply power to the robot from the
pendant or external control systems etc. As a part of the total safety concept, a
precondition for applying power by this function is that hardware motor-on has been
activated. An attempt to apply power to the robot from the pendant without having
activated the hardware motor-on will result in a warning message. Software will
always switch off this signal when hardware is not allowing motor-on.

5.4.6 Emergency Brake Release Switch
General

A switch may be installed to enable releasing the axis brakes for the robot in an
emergency situation. This may be a situation where a person is trapped by the robot
arm and brakes can not be released quickly by normal means, e.g. at power failure
or the pendant is not at hand.

Installation

The emergency brake release switch should be a switch installed behind a breakable
glass (like a fire alarm) to prevent the switch from being used for normal brake
release purposes. The switch must be marked with a warning sign informing that
using the switch will violate the spray booth explosion safety functions.
The switch must be placed in a convenient location outside the spray booth with a
clear view of the robot.
WARNING! The emergency brake release switch will apply 24VDC to the axis

brakes even if the purge system is not active and must only be used in emergency
situations.

5.5.3 Cabin Interlock
General

The purpose of the cabin interlock chain is to disable paint functions which are
emitting flammable material (paint, solvent, etc.) into the cabin, if vital cabin
functions are not present, like the cabin ventilation (cabin fans), fire extinguishing
system. This is achieved by including dual switches on the cabin fan relay in the
cabin interlock chain.

Description

When the cabin interlock chain is broken, +24V_FUNC will be disconnected from
the manipulator board and one of the VCD modules. Paint functions connected to
these modules (via pilot valves) will thereby be disabled. Paint functions which are
normally connected to these modules are spray-gun needle, shaping air, etc.
Paint functions connected to the other VCD modules, powered by +24V_MAN, will
not be affected by the cabin interlock chain. Typical connections to these modules
are color change, etc.
Which functions that are interlocked and not interlocked can be found in the Process
Diagram.
When breaking the cabin interlock chain, the system will use approx. 1/2 second to
make a controlled stop of the paint functions. When closing the chain, power will be
re-applied to the interlocked paint control functions, and operation can continue.
Following conditions must be present to close the cabin interlock chain.
– Cabin interlock chain must be closed. (Cabin ventilation fans must be running).
– The emergency stop- and enable chain must be closed.
– Robot must be purged (purge relay must be closed).

Installation

To install the Cabin Interlock switch, install a 2 pole switch at terminals marked
‘Cabin Interlock’ (for chain 1 and 2) in connector SCB-X3 pin 1-4 as shown in
Figure 34 and in principle diagram in Figure 35. The switch must be of a Normal
Open fail safe type, which will be opened to disable paint functions.
The switch must comply with ’Safety System Standards’ on page 65.

5.6 Encoder and Sync Switch Installation

5.6 Encoder and Sync Switch Installation
5.6.1 Introduction
General

Conveyor tracking is a function to be used when the robot is operating on objects on
a moving conveyor line. By using the tracking function, the robot programs will be
executed correctly in relation to the work object, independent on how the work
object moves on the conveyor.
To enable the tracking function, a conveyor encoder and a sync switch must be
installed on the conveyor and the robot must have been supplied with the tracking
function.
The following sections provide information on the installation and connection of the
encoder and sync switch. For information on how to enter the required data and
parameters for setting up the tracking function, see ‘Operator’s Manual, IRC5P’.

Important
Considerations

To ensure good operation of the tracking function, following points must be
observed:
• The robot or robots (and trolley rail system if used) must be installed as
accurately as possible, which normally means at about +/- 0.5 mm maximum
deviation from theoretical positions.
• If robots are installed on both sides of the conveyor, the robots and rails must
also be installed symmetrically relative to the object, so that mirroring of robot
programs can be possible in the same part of the robot’s work envelopes.
• The conveyor must be able to run steadily at all speeds to avoid jerky or
swinging motions of the work objects on the conveyor.
• It must be possible to install an encoder at a location which will reflect the true
speed of the conveyor in front of the robot. This means a location as close to the
robot as practically possible.
• The distance between the encoder and the connection point for the encoder
(control cabinet) should be kept as short as practically possible to minimize the
effect of noise on the encoder signal.
• One encoder may be connected to serve more than one robot.

Product Manual, Control Cabinet IRC5P

5.6 Encoder and Sync Switch Installation

5.6.2 Encoder Specifications
General

The encoder is used to inform the robot control system of the position (motion) of
the conveyor to enable the tracking function to run the robot program correctly in
relation to the work objects on the conveyor. The tracking function is obtained by
installing the encoder on the conveyor and enter the signal from the encoder to the
control system via terminals in the control cabinet.

Encoder Type

The encoder must be of 2 phase type to enable registration of reverse conveyor
motion and to avoid ‘false counting’ related to vibration etc. when the conveyor is
not moving. The encoder can be PNP or NPN type.

Number of Pulses

The number of pulses per meter must be selected in relation to the speed of the
conveyor and the gearing between the encoder and the conveyor. The parameter
value should be between 1250 and 5000 cycles per meter.
In the following, we use this notion: Counts = cycles = 4 * pulse transitions. The
robot motion controller uses all the pulse transitions, so that the number of
increments used will be 4 times the number of full cycles from the encoder. The
system specifies only one count per cycle in the parameter (see pulse diagram in
Figure 37). This means that the controller will read 5000 - 20000 pulses for the
encoder cycle ratio given above. Reducing the number of pulses below 5000 will
reduce the accuracy of the robot (5000 pulses/m = 0.2 mm/pulse). Increasing the
value beyond 10000 will have no significant effect as inaccuracies in robot and cell
calibration will be dominant. High values may however introduce a max. frequency
problem if long cables are used.

Recommended Encoder

The recommended Lenord and Bauer encoder shown below includes connections
for supply voltage and 2 output phases with 90° phase shift. The sync pulse
connection is not used.

5.6 Encoder and Sync Switch Installation

Rotating Direction

The physical rotating direction of the encoder after installation is dependent on the
design of the arrangement connecting the encoder to the conveyor. Basically, both
rotating directions can be equally used, but it is required that it counts ‘up’ when the
conveyor moves forwards and counts ‘down’ when the conveyor moves backwards.
The rotating direction of the encoder can be changed electrically by interchanging
the 2 phases (0° and 90°) of the output signals, - Ref: Figure 40.
For information on how to find encoder rotating direction, see ‘Operator’s Manual,
IRC5P’, chapter ‘Installation and Commissioning’.

Technical Specifications
Output signal:

Open collector PNP or NPN output

Voltage:

10-30V (normally supplied by 24VDC from robot)

Current:

Max. 10mA (for each connected robot)

Phase:

2 phase with 90 degrees phase shift

Duty cycle:

50%

Max. frequency:

40KHz *

* Maximum frequency is strongly dependent on cable quality and cable length.
Recommended cable is 3 pair screened cable.
Encoder Noise
Suppression

The encoder must be connected using a screened cable. If this cable is long, the
inductance in the cable will produce spike pulses on the encoder signal which may,
over a period of time, damage the opto couplers in the control electronics. The spike
pulses (which can be of considerable amplitude), can be removed by installing a
capacitor between the signal wire and ground for each of the 2 phases. The
capacitors should be connected at the encoder end, not on the electronics end.
Typical capacitor value is 100 nF - 1 µF, depending on the length of the cable
(longer cable, larger capacitor). The correct capacitor can be found by viewing the
encoder signal using an oscilloscope.

5 Installation and Commissioning
5.6 Encoder and Sync Switch Installation

5.6.3 Sync Switch Specifications
General

The sync signal (synchronization signal, sometimes called start signal) is used to
enter the position of the work object on the conveyor into the robot control system.
The sync signal is entered by installing a sync switch on the conveyor. The sync
switch will detect each object as it passes the switch.
LEDs labelled Start 1 / 2 (Start 1 and Start 2) for sync switch 1 (and sync switch 2 if
two sync switches are installed) indicating the operation of the sync switch are
present on the control cabinet LED display.

Switch Specification

The sync switch should be selected so that it provides a reliable and repeatable
signal for the work objects on the conveyor, regardless of conveyor speed. The
switch arrangement must be designed so that it only gives one signal for each work
object, and that it does not give any signal if the work object should happen to pass
the switch in backwards direction. (If the switch gives multiple signals when an
object passes, the parameter SyncFilter can be set so that only one signal is
accepted. For information, see ‘Operator’s Manual, IRC5P’).

Switch Types

Different types of switching devices may be used. Most common is a limit switch,
but photocell with switch output or Namur initiator etc. may also be used.

Switch Location

The sync switch may be installed in the hazardous area of the spray booth or in the
non-hazardous area outside the spray booth. Different requirements apply to the
switch and its connection to the control system in these situations. For information,
see ’Sync Switch Connection - General Information’ on page 95.

5.6.5 Encoder Installation
General

The encoder must be installed in such a way that it gives a precise feedback of the
conveyor motion (reflects the true conveyor motion). This means that the encoder
should be installed as close to the robot as practically possible, typically not more
than 30 meters away, and that a good connection between the encoder shaft and the
conveyor should be made.

CAUTION! The encoder is a sensitive measuring device and it is for this reason
important that no other forces than the shaft rotation is transferred from the
conveyor to the encoder, and that the encoder is mounted using shock absorbers to
prevent damage from vibration.

Mechanical Connection

The encoder can be installed in conjunction with the conveyor drive unit or
connected via a chain system, called ‘auxiliary chain’, gripping into the conveyor
chain. The encoder shaft can be connected to the shaft of the conveyor drive wheel
or one of the wheels of the ‘auxiliary chain’.
Important: The encoder must not be connected directly to the conveyor drive unit

itself, as play in the drive belt will not be registered, and, if the drive belt should
break, the robot will operate as if the conveyor was still running.

Using Flexible Coupling

The connection can be performed either directly to the shaft via a flexible coupling,
or more commonly via a drive belt, chain- or gear wheel arrangement. If a flexible
coupling is used, it must be a coupling specially designed for this purpose. A
coupling using a plastic/rubber hose should be avoided as it makes a connection
which is too stiff and thereby may cause damage to the encoder.

Conveyors with
‘Take-Up’ Station

If a ‘Take-Up’ is used (used to keep tension in the conveyor chain), the encoder
must be placed on the same side of the ‘Take-Up’ station as the robot.

• One encoder used to serve two or more robots.
• Two encoders to provide a backup encoder.
CAUTION! The encoder must be connected using a screened cable. If the cable is

Connection for NPN encoder

The encoder is connected to inputs on connector X5 - X7 on the SCB board in the

The 2 phases, A(0°) and B(90°), must be connected so that the encoder counts ‘up’
when the conveyor moves forwards and counts ‘down’ when the conveyor moves
backwards. For information on finding the rotating direction, see ’Rotating
Direction’ on page 88.
Connections for the second encoder shown above can only be used if the 2nd
encoder is to be used as backup.
The 2 LEDs for each of the encoders on the cabinet LED display will flash to show
the pulses from the encoder. By running the conveyor extremely slowly, these
indicators can be used to verify the pulses from the encoder.

Connection for NPN encoder

If the power supply is taken from the robot, the supply must be connected to all the
robots to make sure that the encoder will be operational even if one robot is
switched ‘off’. When supplying power from the robots in this way, it is important
that a diode is installed for each robot to prevent power from one of the robots
which is ‘on’ to be fed to a robot which is ‘off’.
If an external supply is used, the internal supply must not be connected.

To reduce possible variation in the synchronization signal due to uneven conveyor
motion, swinging of work objects etc., the switch should be placed as close to the
robot as practically possible.
The switch may also be placed outside the hazardous area. This location must be
used if a non-ex switch and non-ex connection is used. The switch can be installed
on a bracket mounted on the conveyor.

Initiator Mounting

If an initiator is used, the initiator should be installed to detect the object directly, or
detecting the object suspension (a flag on the suspension) etc.

‘Normal’ Switch
Mounting

If a ‘normal’ switch is used, the switch arm must be in a perpendicular position in
relation to the work object when the switch is activated. If the switch is installed as
indicated in the two illustrations at the right, there is a risk that the work object (or
suspension) will slide on the switch arm, causing inaccurate switching.

Installation Procedure

This procedure describes how to install the cooler on the control cabinet.
If the cooler is ordered together with the robot and control cabinet, the cooler is
already installed and this installation procedure can be skipped. Continue with
’Installation Checks’ on page 106.
1.

Remove cooler from box. Be careful when lifting cooler.

Remove paper on gasket adhesive surface. Place gasket on cabinet mounting
surface with adhesive side facing cabinet. Pay attention to get gasket correctly
positioned.

Place cooler on its side and install 8 supplied headless screws.

Open cabinet front door. Lift cooler onto side of cabinet. Guide headless screws
into attachment holes.

Install washers and nuts on screws from inside cabinet. Tighten nuts.

As the air inside the cabinet is cooled down, condensation arises in the cooler. It
is therefore important to make an arrangement as shown in the illustration to
lead the condensate from the cooler to the outside of the cabinet.

Important: To minimize condensation, it is important to set the internal temperature

(default 38°C) not lower than actually needed. To prevent condensation inside the
control cabinet, ensure that the control cabinet is a sealed enclosure, especially
watch cable inlets and door seals.

Installation Checks

Install door switch. Cooling is switched off when control cabinet door is open.

Install connector X79 and terminal X78. The external 115 or 230 VAC is
connected to terminal board XT1.1, located beside the mains overload
protection, FR1, in the lower left bottom of the controller as shown in
Figure 17. See also ’Supply for Internal Light’ on page 118.

Insert electrical connector of the cooler into X79.

After the installation has been performed, and if the cooler has been installed before
shipment, it is important to check the following:
– To prevent condensation inside the control cabinet, ensure that the control
cabinet is a sealed enclosure, especially watch cable inlets and door seals.
– Ensure that the condensate from the cooler is lead to the outside of the control
cabinet.
– Ensure that the door switch is open when the control cabinet door is open. To
minimize condensation inside the control cabinet, cooling is switched off when
control cabinet door is open.

Important: Due to the autotransformer / drive system / mains filter configuration in

the IRC5P controller, an imbalance between the supply phases to the system can
occur during operation of the robot, and especially when switching the system ‘on’
and when applying power to the robots drive system (Motor On). This may cause
the earth fault protection to trip if a protection with too low release current is used,
and especially if more robots share the same earth fault protection.

6 Preventive Maintenance
6.1 Introduction

6 Preventive Maintenance
6.1 Introduction
About this Chapter

This chapter provides instructions for performing scheduled preventive
maintenance on the control cabinet.
The preventive maintenance is based on a maintenance chart with information about
required maintenance activities including intervals, and references to procedures for
the activities.
Note that the intervals described are recommended intervals. The intervals needed
for your installation may vary, depending on environmental conditions, number of
working hours etc. The maintenance routines in this description must be seen in
relation to the plant’s own maintenance routines for the paint equipment.

Safety Information

Before any work described in this chapter is commenced, it is extremely important
that all information concerning safety is carefully studied.
There are general safety aspects that must be read through, as well as more specific
safety information that describes danger and safety risks when performing the
procedures. Read the Safety Manual before performing any service work.
WARNING! No maintenance work must be performed on the controller before the

safety guidelines in the ‘Safety Manual’ have been read and understood. Work must
only be performed by skilled personnel with the proper training.

General Considerations

The prime objective of any preventive maintenance program is to ensure maximum
system availability. Each scheduled and properly performed preventive maintenance
activity should assist in realizing this objective. Preventive maintenance that does
not reduce system downtime is unnecessary and costly.
The robot and paint system is designed to be able to work under very demanding
conditions with a minimum of maintenance. Nevertheless, certain routine checks
and preventative maintenance must be carried out at given periodical intervals.
When performing routine maintenance or repair work, a number of precautions
must be kept in mind to avoid introducing additional errors into the system.
• Do not perform more than recommended preventive maintenance on equipment
which is working satisfactorily.
• Wipe all surfaces clean before starting maintenance procedures.
• To avoid unnecessary contamination by dust etc., always clean outside of control
cabinet and manipulator before opening the cabinet door.

7.1 Introduction
About this Chapter

This chapter details all repair activities recommended for the controller.
It is made up of separate procedures, each detailing a specific repair activity. Each
procedure contains all information required to perform the activity, such as required
tools and items.

Safety Information

Before any work described in this chapter is commenced, it is extremely important
that all information concerning safety is carefully studied.
There are general safety aspects that must be read through, as well as more specific
safety information that describes danger and safety risks when performing the
procedures. Read the Safety Manual before performing any service work.
WARNING! No repair work must be performed on the robot before the safety

guidelines in the Safety Manual have been read and understood. Work must only be
performed by skilled personnel with the proper training.

Organization of
Procedures

The procedures are divided into a procedure for removal and a procedure for
refitting. At the start of each procedure, a reference list shows information located
other places in the manual than in the procedure. If you want to print out a
procedure, you should also print the information referred to under reference to get
all information you need to perform the repair operation.
The manual describes the type of service work that can be carried out by the
Customer´s own service staff on site. Certain types of work, requiring special
experience or special aids, are not dealt with in the manual. In such cases, the
defective module or component should be replaced on site. The faulty item should
be sent to your local ABB organization for service.

Replacement Items

Make sure that any replacement items are available before performing any repair
procedures. Use only replacement items listed in the spare parts catalogue.

Purge System

During operation, the manipulator is supplied by compressed air (ex-version). For
this reason, the robot can not operate unless all covers are in place and properly
sealed. Missing screws will cause air leaks and result in increased air consumption
or failure in the purge system. This does not apply for non-ex robots.

Tightening Torque

Generally, all screws must be tightened with correct torque, as described under
’Tightening Torques’ on page 216.

7.1 Introduction

Tools

All repair activities on the control cabinet can be performed with normal hand tools.

Illustration References

References to illustrations are placed in brackets ( ) indicating figure number and
position in the figure. Example: (15/3) means figure 15 position 3.

Calibration

Calibration of the robot must be performed after replacing mechanical parts, when a
resolver error has occurred or when the power supply between a measuring board
and resolver has been interrupted etc.
Calibrating the robot means to place the robot arm and wrist in a specific position
and enter resolver data for this position into the control system. To place the arm
and wrist in this position, a calibration fixture must be available.
For description of the calibration function and procedure for entering calibration
data, see ‘Operator’s Manual - IRC5P’.

ESD Precautions

Electronic devices are sensitive to static electricity. If handled incorrectly, the unit
may be permanently damaged. Following precautions should be taken at all times
when handling sensitive electronic units.
• ALWAYS keep electronic units protected in static shielded plastic bags when not
installed in the robot. These bags are made from a special conductive material
which will prevent build-up of static electricity.
• ALWAYS wear wrist strap when installing or removing electronic units in the
controller. The strap is grounded on the control cabinet. The wrist strap includes
a 1Mohm resistor and is of no danger with respect to electric shock hazards. The
wrist strap is located inside the controller on the cabinet front door on left hand
side of the computer unit.
• NEVER place electronic components on a conductive surface such as an iron
plated table or the control cabinet top etc.
• NEVER store or place sensitive electronic devices near strong electrostatic,
magnetic or radioactive fields.

8 Trouble Shooting
8.1 Introduction
About this Chapter

This chapter contains information, procedures and descriptions for trouble shooting
IRC5P based robot systems. The information should be used when the robot
operation is interrupted by malfunction, regardless of whether an error event log
message is issued or not.
The chapter is divided into 4 sections as follows:
• General description of trouble shooting routines and valuable hints on how to
perform trouble shooting.
• Listing of some relevant fault symptoms and malfunctions.
• Trouble Shooting instructions for some individual units.
• Description of the LED indicators on the controller front.
For description of the LED indicators on the separate units inside the controller, see
descriptions of the different boards and units in ‘Unit Description, IRC5P’.
Note: The trouble shooting described in this chapter must be used in combination

with the event messages described in the ‘Operating Manual, Trouble Shooting’.

8.2 General Description and Hints

8.2 General Description and Hints
8.2.1 Trouble Shooting Strategies
General

Trouble shooting complex technical systems such as robot systems requires a
systematic approach. The personnel must be trained and qualified to perform the
task, and will be helped by using the correct tools and methods.

Isolate the Fault

Any fault may give rise to a number of symptoms, for which error event log
messages may or may not be created. In order to effectively eliminate the problem,
it is vital to distinguish the original symptom from the consequential ones.
A help in isolating the fault may be creating a historical fault log as specified in
section ’Keep Track of History’ on page 173.

Split the Fault Chain

When trouble shooting any system, a good practice is to split the event chain in two.
This means:
• Identify the complete chain of events.
• Decide and measure the expected value at the middle of the chain.
• Use this to determine in which half the fault is caused.
• Split this half into two new halves, etc.
• Finally, a single component may be isolated, the faulty one.

Check Communication
Parameters and Cables

The most common causes of errors in serial communication are:
• Faulty cables (e.g. send and receive signals are mixed up).
• Transfer rates (baud rates).
• Data widths that are incorrectly set.

Check Software
Versions

Make sure the RobotWare and other software are the correct versions. Some SW
versions are not compatible with certain hardware components.
Also, make a note of all software versions, since this will be useful information for
service and support.

8.2.2 Documentation and References
General

A great deal of effort was put into writing the event log messages as well as the
technical documentation. The messages can never be perfect, but they may give
vital clues. They are also constantly being upgraded.

Read the Documentation

Reading the manual should be done not only as a last resort.
Product documentation is available electronically as pdf files on the DVD-ROM
supplied with the robot.

Study the Circuit
Diagram

The complete electrical circuitry of the controller and manipulator is available on
the DVD-ROM shipped with the robot. These circuit diagrams contain a lot of
useful, or even essential, information to a trained trouble shooter.

Read the Logs.

The event logs contain lots of information about operations and malfunctions
detected by the system. For information on operating the logs, see the ‘Operator’s
Manual IRC5P’, section ‘Running in Production’ / ‘Logging and Diagnostics’.

Check LED Indicators

Check the LED indicators on the LED panel on the controller front for information
on possible malfunction.
Faults caused by electronic units are indicated by the LEDs on the unit front. These
LEDs are described under the different boards and units in ‘Unit Description,
IRC5P’.

8 Trouble Shooting
8.2 General Description and Hints

8.2.3 Work Systematically
Do Not Replace Units
Randomly

Before replacing any part at all, it is important to establish a probable cause for the
fault, thus determining which unit to replace.
Randomly replacing units may sometimes solve the acute problem, but also leaves
the trouble shooter with a number of units that may or may not be perfectly
functional.

Replace one Component
at a Time

When replacing a presumably faulty unit that has been isolated, it is important that
only one unit is replaced at a time.
Always replace components according to procedures in the Repair chapter of the
product manual for the manipulator and controller at hand.
Test the system after replacing to see if the problem has been solved.
If replacing several units at once:
• It is impossible to determine which of the units was causing the fault.
• It greatly complicates ordering a new spare part.
• It may introduce new faults to the system.

Take a Look Around

Often, the cause may be evident by visual inspection. In the area of the unit acting
erroneously, be sure to check:
• Are the attachment screws secured?
• Are all connectors secured?
• Are all cabling free from damage?
• Are the units clean (especially electronic units)?
• Is the correct unit fitted?

Check for Tools Left
Behind

Some repair and maintenance work require use of special tools to be fitted to the
robot equipment. If these are left behind (e.g. a signal cable to a computer unit used
for measuring purposes), they may cause erratic robot behavior.
Make sure all tools are removed when maintenance work is completed.

8.2 General Description and Hints

8.2.4 Keep Track of History
Make a Historical Error
Log

In some cases, a particular installation may give rise to faults not encountered in
others. Therefore, a log of each installation may give valuable assistance to the
trouble shooter.
To facilitate trouble shooting, a log of the circumstances surrounding the fault gives
the following advantages:
• It enables the trouble shooter to see patterns in causes and consequences not
apparent at each individual fault occurrence.
• It may point out a specific event always taking place just before the fault, for
example a certain part of the work cycle being run.
• When an error occurs, keep track of the last operations done by the robot.

Check Up the History

Make sure you always consult the historical log if it is used. Also remember to
consult the person who was observing the problem.

At What Stage did the
Fault Occur

What to look for during trouble shooting depends greatly on when the fault
occurred: Was the robot just freshly installed? Was it recently repaired?
The table gives specific hints to what to look for in specific situations:
If the system has just:

8.2.5 Upgrading, Downgrading and Compatibilities
Overview

Each part of the system is of a specific release, software as well as hardware.
Changing to a later release is called upgrading and changing to an earlier is
downgrading.
Upgrading and downgrading may cause compatibility problems, for instance a
specific circuit board may work well with one release but not with another.
Since the robot system is complex, and since the system often works in connection
with a large number of additional equipment, keeping track of each
hardware/software combination is difficult.

Technical Service
Information

Each software release is accompanied by a Technical Service Information, TSI,
which includes a description of how to perform an upgrade/downgrade, and a list of
known incompatibilities.
For information about a specific TSI, please contact your local ABB organization.

8.3.5 Controller Performance Slow
Description

The controller performance is slow, and seems to work irrationally.
The controller it not completely ‘dead’. If it is, please proceed as described in
section ’Controller Dead’ on page 178.

Consequences

These symptoms may be observed:
• Program execution is sluggish, seemingly irrational and sometimes stalls.

Possible Causes

The computer system is experiencing too high load, which may be due to one or
more of the following:
• Programs containing too many logical instructions without Wait or Moveinstructions, causing too fast program loops and in turn, overload the processor.
• The poll rate of the I/O units is set too low, overloading the I/O system.
• Internal system cross connections and logical functions are used too frequently.
• An external PLC, or other supervisory computer, is addressing the system too
frequently, overloading the system.

Recommended Actions
Step Action

Comment

Check whether the program contains almost
only logical instructions (or other instructions
that take ‘no time’ to execute), since such
programs may cause the execution to loop if no
conditions are fulfilled. To avoid such loops, you
may test by adding one or more WAIT
instructions. Use only short WAIT times, to
avoid slowing the program down unnecessarily.

Suitable places to add WAIT instructions
may be:
– In a WHILE/FOR/GOTO loop,
preferably at the end, close to the
ENDWHILE/ENDFOR etc. part of the
instruction.
– In an auto-looping background task,
ref. Rapid OverView/Multitasking

Make sure the poll rate value for each I/O board
is not too low. These values are changed using
RobotStudio. I/O units not requiring to be polled
regularly may be switched to ‘change of state’
operation as described in the RobotStudio
manual.

ABB recommends these poll rates [ms]:
– DSQC 651: 1000
– DSQC 652: 1000
– DSQC 653: 1000
– DSQC 377: 20-40
– All others: >100

Check whether there is a large amount of cross Too much communication with PLCs or
connections or I/O communication between

the communication.

Make sure there is little unnecessary
communication between any supervisory PLCs
or other computer. Make sure the PLC is
programmed in such a way that it does not, for
example, request robot system state changes
that are not allowable, by letting the PLC
monitor robot system state through a digital
input. Also make sure, that such state change
requests are not issued too often.

Product Manual, Control Cabinet IRC5P

The robot system have a number of
fixed system inputs and outputs that may
be used for this purpose. Too much

8.3.14 Oil or Grease Stains on Motors and/or Gearboxes
Description

The area surrounding the motor or gearbox shows signs of oil leaks. This may be at
the base, closest to the mating surface, or at the furthest end of the motor at the
resolver.

Consequences

Except for the dirty appearance, in some cases there are no serious consequences.
However, in some cases the leaking oil lubricates the motor brake, causing the
manipulator to collapse at power-down.

Possible Causes

The symptom may be caused by (the causes are listed in order of probability):
• Leaking seal between gearbox and motor.
• Gearbox overfilled with oil.
• Gearbox oil too hot.

Description

During operation, no abnormal mechanical noise should be heard from motors,
gearboxes, bearings or similar. A faulty bearing often makes scraping, grinding or
clicking noises shortly before failing.

Consequences

Failing bearings cause the path accuracy to become inconsistent, and in severe
cases, the joint may be completely damaged.

Possible Causes

The symptom may be caused by:
• Worn bearings.
• Contaminations have entered the bearing races.
• Loss of lubrication in bearings.
• Overheating (If the noise comes from a gearbox).

Recommended Actions

CAUTION! Parts of the manipulator may be hot and care must be taken to avoid

This section includes information on cables which should be used for the
installation.

Signal Classes

Power Supplies external motors and brakes.
Control signals Digital operating and data signals (digital I/O, safety stop, etc.).
Measuring signals Analog measuring and control signals (resolver and analog
I/O).
Data communication signals Gateway (field bus) connection, computer link.
Different rules apply to the different classes when selecting and laying cable.
Signals from different classes must not be mixed.

All cables laid in the controller must be capable of withstanding 70°C. In addition,
the following rules apply to the cables of certain signal classes:
Power Signals Shielded cable with an area of at least 0.75 mm² or AWG 18. Note
that any local standards and regulations concerning insulation and area must always
be complied with.
Control Signals Shielded cable.
Measuring Signals Shielded cable with twisted pair conductors.
Data Communication Signals Shielded cable with twisted pair conductors. A
specific cable should be used for Gateway (field bus) connections and Ethernet.
CAN bus with DeviceNet for Distributed I/O units Thin cable according to
DeviceNet specification release 1.2, must be used. The cable is shielded and has
four conductors, two for electronic supply and two for signal transmission. Note that
a separate cable for supply of I/O loads is required.

Interference Elimination

Internal relay coils and other units that can generate interference inside the
controller are neutralized. External relay coils, solenoids and other units must be
clamped in a similar way. The illustration in Figure 87 shows how this can be done.
Note that the turn-off time for DC relays increases after neutralization, especially if
a diode is connected across the coil. Varistors give shorter turn-off times.
Neutralizing the coils lengthens the life of the switches that control them.

The diode is to be dimensioned for the
same current as the relay coil, and a
voltage of twice the supply voltage.

10.2 Connection Types

10.2 Connection Types
General

Inter-connections between the different components of the robot system, and
external connections may be performed using connectors, connectors with screw
terminals, terminal boards with screw terminals or spring terminals, depending on
how the robot is specified etc. The following sections provide general information
on the different types of connections which are- or may be used in the system.
Note: Bend unused conductors backwards and attach them to the cable using a

clasp etc. In order to prevent interference, ensure that such conductors are not
connected at the other end of the cable (antenna effect). In environments with much
interference, disconnected conductors should be grounded (0 V) in both ends.

Connection to Screw
Terminals

The robot may include terminal boards or connectors with screw terminals for
connection of wires with area between 0.25 - 1.5mm². A maximum of two wires
can be connected to each terminal provided that a protection sleeve is installed on
the two wire ends. The cable screen must be connected at the lead-through in the
cabinet, - Ref: ’Clamping Cables’ on page 213.

Connections to Spring
Terminals

The robot may include terminal boards with spring connection of wires with area
between 0.25 - 1.5mm². Only one wire can be connected to each of these terminals.
The cable is released from the connection by inserting a screwdriver in a slot beside
the connection point. The cable screen must be connected at the lead-through in the
cabinet, - Ref: ’Clamping Cables’ on page 213.

Connection to
Connectors

Industrial connectors with varying number of pins for contact crimping are used in
the robot. Some options installed in the cabinet may also use these types of
connectors.
When contact crimping industrial connectors, the following applies:
Using special tongs, press a pin or socket on to each non-insulated conductor.
The pin can then be snapped into the actual contact.
Push the pin into the connector until it locks.
Also, see instructions from contact supplier.
A special extractor tool must be used to remove pins from industrial connectors.
When two conductors need to be connected to the same pin, both of them are
pressed into the same pin. A maximum of two conductors may be pressed into any
one pin.

10.3 Bonding Information

10.3 Bonding Information
General

Grounding or PE ground means the connection to protective earth. IS ground is
ground connection for the ex-systems. Bonding means additional ‘grounding’ to
protect sensitive signals from RF noise etc.
When the PE ground and IS ground connections of the robot components have been
performed in accordance with the description in this manual, the electronics
components in the shielded environment of the cabinet and manipulator are well
protected against electric noise.
To ensure proper operation of the robot system when electronic devices such as
external PLC, communication nodes, external cabinets etc. are placed outside these
protected environments, it is extremely important that proper bonding is provided
for the external units and corresponding communication cables.
In the following you will find information and hints on how proper bonding can be
obtained. For more information on protecting of signal cables etc., books describing
the subject are available on the market.

Bonding Connections

When the robot is installed in accordance with the description in this manual, all
components of the robot system; control cabinet, manipulator, purge unit and
possible external cabinets etc. will be connected by a firm bonding wire as part of
the robots design. Additional external equipment installed must be connected by a
bonding wire of minimum 16mm2 (AWG 4). The wire must be firmly connected to
the bare metal of the component with a solid screwed connection. A solid
connection like this will ensure that no voltage potential can be built up between the
different units.
If the robot, control cabinet, purge unit, spray booth door switch or any other device
in the robot system is mounted on a metal surface, the user must make sure that
these surfaces are properly grounded.
CAUTION! No components in the robot system must be mounted on metal surfaces
which are not properly grounded.

the components (the amount of noise which can be induced in the component
casing), the distance to the component, the signals sensitivity to noise and present
noise in the installation etc.

Method B - Cables connected to connectors away from the strain relief rail
A section of the cable must be dismantled and clamped to the strain relief rail. The
cable is then routed to the connection point where the screen is clamped to the
cabinet frame using p-clip as shown in Figure 89 center. For the motor/signal cable
connected to X11 and X12, it must be observed that both the outer screen for the
motor cable and the inner screen for the signal cable must be secured under the
clamp. Ref. Figure 89 inset.
Method C - Cables for sensitive signals
Cable for extra sensitive signals such as analog signals must be grounded at the
component where it is connected in addition to the ground connection on the strain
relief rail as shown in Figure 89 right.
CAUTION! Do not use excessive force when tightening clamps. Tightening clamps
too hard may damage cable and signal wires.

Alternative Bonding
Methods

The following shows 3 examples on how the signal cable screens can be bonded:
Figure 90 Bonding examples

Junction box etc.

External unit
Example 1
Ground all screens
when a good ground
connection is available

Example 2
Do not ground screen
at end where good
ground is not available
Example on noise
supression capacitor

Interconnect screens at
this point if single cable
cannot be used

Example 3
Interconnect screens
but do not connect to
ground in external units
when good ground is not
available

Example 1
Where a good bonding is available on all units, the best shielding is obtained by
bonding all screens at both ends on all units.
Example 2
If a solid bonding connection can not be provided e.g. for an external unit such as a
communication node, I/O unit, PLC or a sensor etc., the screen for the cable must
not be bonded at the unit without a good bonding connection. This situation is
shown in Figure 90, example 2. If the cable is routed and terminated in a junction
box etc. and the junction box has a good bonding connection, the screens for both
cables must be bonded at this point.
Example 3
If the cable is terminated in a junction box or other unit where a good bonding is not
available, the screens of the 2 cables must be connected as shown in Figure 90,
example 3, but not connected to the chassis of the unit.

10 Reference Information
10.3 Bonding Information

Hints

• You may check that the bonding is good by using an oscilloscope with an EMI
probe (Electro Magnetic Interference). By setting the oscilloscope to a relatively
high frequency and measuring on the screens and chassis of the different units in
the system, possible noise can be seen on the oscilloscope screen.
• If noise is present in the situations shown in Figure 90 example 2 and 3, a
ceramic capacitor of e.g. 0.22µF can be installed between the screen and chassis
as shown in example 3.
• Cables of different types such as signal cables and power cables must not be
routed together as the power cables may introduce noise in the signal cable.
• If the bonding has been performed according to the general guidelines given here
but noise is still present, there is a good chance that the bonding wire used are of
too small square in relation to the length of the wire or that the connections
between the bonding wire and/or screens are not good enough.
