Safety Instructions
Overview
This chapter contains safety instructions which must be complied
with during installation, operation and maintenance of the power
converters series DCS 500B / DCF 500B or DCP 500B. If these instructions are not complied with, this may result in injuries (perhaps
even with fatal) or in damage to the power converter, the motor and
the driven machine. Before starting with any work whatsoever at or
with this unit, you must read the information given in this chapter.
Warnings
Warnings provide information on states which if the specified procedure for the state concerned is not meticulously complied with
may result in a serious error, in major damage to the unit, in injury
to persons and even in death.
They are identified by the following symbols:
Danger: High Voltage! This symbol warns you of
high voltages which may result in injuries to persons
and/or damage to equipment. Where appropriate, the
text printed adjacent to this symbol describes how
risks of this kind may be avoided.
●
●
●
●
All electrical installation and maintenance work on the thyristor
power converter must be carried out by properly qualified staff
who have been thoroughly trained in electrical engineering.
The thyristor power converter and its adjacent units must be
properly earthed by qualified professionals.
You must NEVER perform any work on the thyristor power converter while it is still switched on. First switch the unit off, use a
measuring instrument to make absolutely sure that the power
converter has really been de-energized, and only then you may
start with the work concerned.
Due to external control circuits, there may be dangerously high
voltages present at the thyristor power converter even after the
line voltage has been switched off. So always work at the unit
with appropriate caution! Non-compliance with these instructions
may result in injury (or even death!).

Safety Instructions
General warning: this symbol warns you of nonelectrical risks and dangers which may result in serious or even fatal injury to persons and/or in damage
to equipment. Where appropriate, the text printed adjacent to this symbol describes how risks of this kind
may be avoided.
● When thyristor power converters are in use, the electric motors,
power transmission elements and the driven machines are working in an extended operating range, which means they have to
cope with a relatively high loading.
● You should have made sure that all units, devices and appliances used are actually suitable for this higher loading.
● If you have to operate the thyristor power converter at a rated
motor voltage and/or a rated motor current significantly below
the figures stated in the thyristor power converter's output data,
you must take appropriate precautionary measures to protect the
unit against overspeed, overload, breakage, etc., by modifying
the software or hardware appropriately.
● For insulation testing, you must disconnect all cables from the
thyristor power converter. You should avoid operating your unit
at values other than the rated data. Non-compliance with these
instructions may cause lasting damage to the thyristor power
converter.
● The thyristor power converter possesses a number of automatic
reset functions. When these functions are executed, the unit will
be reset after an error and will then resume operation. These
functions should not be used if other units and devices are not
suitable for an operating mode of this kind, or if their use might
entail dangerous situations.
Warning of electrostatic discharge:
this symbol warns you against electrostatic discharges
which may damage the unit. Where appropriate, the
text printed next to this symbol describes how a risk of
this kind may be avoided.

Safety Instructions
Notes
Notes supply information on states requiring particular attention, or
indicate that additional information is available on a specific topic.
For this purpose, the following symbols are used:
CAUTION!
Cautions are designed to draw your attention to a
particular state of affairs.
Note
A note contains or refers you to additional information available on the particular topic concerned.
Mains connection
You can use a switch disconnector (with fuses) in the power supply
of the thyristor power converter to disconnect the electrical components of the unit from the power supply for installation and maintenance work. The type of disconnector used must be a switch disconnector as per EN 60947-3, Class B, so as to comply with EU
regulations, or a circuit-breaker type which switches off the load circuit by means of an auxiliary contact causing the breaker's main
contacts to open. The mains disconnector must be locked in its
"OPEN" position during any installation and maintenance work.
EMERGENCY STOP
buttons
EMERGENCY STOP buttons must be installed at each control desk
and at all other control panels requiring an emergency stop function. Pressing the STOP button on the CDP 31x control panel of the
thyristor power converter will neither cause an emergency motor
stop, nor will the drive be disconnected from any dangerous potential.
Intended use
The operating instructions cannot take into consideration every
possible case of configuration, operation or maintenance. Thus,
they mainly give such advice only, which is required by qualified
personnel for normal operation of the machines and devices in
industrial installations.
If in special cases the electrical machines and devices are intended
for use in non-industrial installations - which may require stricter
safety regulations (e.g. protection against contact by
children or similar) -, these additional safety measures for the installation must be provided by the customer during assembly.

Check the consignment for any signs of damage. If you find any,
please contact the insurance company or the supplier.
Check the particulars given on the unit's rating plate to make sure
prior to installation and start-up that you have received the correct
unit type and unit version.
If the consignment is incomplete or contains any incorrect items,
please contact the supplier.
CAUTION! The thyristor power converter weighs quite a lot and
should therefore not be held by the front cover. Please put the unit
down only on its back (sizes C1/C2/A5). Always use care when
handling the unit, so as to avoid injuries or damage.
Storage and transport
If the unit had been in storage prior to installation or is transported

Rating plate
For purposes of identification, each thyristor power converter is fitted with rating plates, stating the type code and the serial number,
which serve for each unit's individual identification.
The type code contains information on the characteristics and the
configuration of the unit. The first three digits of the serial number
refer to the year and week of manufacture. The last digits complete
the serial number so as to preclude two units receiving the same
type code and the same serial number.
The 112xx group provides information on the unit's software configuration.
The technical data and specifications are valid as of going to press.
ABB reserves the right to make subsequent alterations.

General notes
CAUTION: it is absolutely essential that the applicable accident prevention
regulations be observed by the user (in this context, please also
read the chapter entitled "Safety Instructions")!
How this chapter is structured
For better understanding the individual steps of start-up work are distinguished by
a) frames without any additional marking on the left side:
These steps of start-up work must always be performed (= mandatory start-up work)!
Example:
522 = GERMAN [Only with the SDCS-CON-2 control board & the CDP 312 panel!]
Activates German texts on the display ...........
b) frames with marking on the left side („columns“ shaded in grey):
These steps of start-up work have to be performed only when the condition stated
(as heading) applies to the selected drive configuration! After this work has been
completed, the mandatory start-up work has to be continued.
Example:
Only when connection diagram 1 (Appendix A) is being used!
906 = 12502
Function „EMERGENCY STOP“ de-activated ............
Recommended motor voltages and field voltages
• Motor voltage UA when the following units are used
(2- quadrant unit)
DCS 501B / DCP 501B:
UAmax = Line voltage * 1.16
(4- quadrant unit)
DCS 502B / DCP 502B:
UAmax = Line voltage * 1.05
• Field voltage UF (= max. output voltage) when the following is being used
SDCS-FEX-1:
UF = Line voltage * 0.9
If there is a divergence of more than 10 % between the field supply unit's output
voltage and the rated field voltage UFrated stated on the motor's rating plate, then the
connecting voltage UN should be reduced, using a matching transformer or a series
Rv = (0.9 * UN - UF) / IF
IF = Rated field current
resistor Rv:
(Note: also suitable for fine-balancing the maximum motor voltage)
• Field voltage UF when the following is being used
SDCS-FEX-2 /
DCF 503 / DCF 504:
UF = Line voltage * 0.6 ... 0.8
• Field voltage UF when the following is being used
DCF 501B / DCF 502B:
UF = Line voltage * 0.5 ... 1.1
Maximally possible output voltage UAmax using
DCF 501B / DCF 502B:
UF = Line voltage * 1.35

Chapter 2 - Start-Up Instructions
Phase sequence when connecting to the mains / Potential isolation
No special phase sequence required for the main connections U1, V1 and W1!
Phase coordination between electronics section and power section not necessary!
For potential isolation and for avoiding ground loops, an isolating transformer should be
installed upstream when an oscilloscope is being used.
Preventing unintended operating states / Shutting the drive down
CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing
unintended operating states), shutting the drive down by means of the
signals at the binary inputs DIx is not sufficient in itself as the sole
measure involved for avoiding unintended operating states or shutting
the drive down in the event of danger!
Range of application for the Start-Up Instructions
The Start-Up Instructions are referenced to the parameter settings in their as-delivered
condition (default values) and to the unit wiring as shown in connection diagram 1 or 2
(see Appendix A). In both circuit variants, the binary inputs DI5, DI7 and DI8 can be used.
They will cause the reactions at the drive as described below.
The symbols stated in this context will be repeatedly used further on in the text.
Method of functioning of the binary inputs DI5, DI7 and DI8
• Binary input DI5; designation EM STOP
In operation, DI5 must be set to logical "1“. If it is set to "0“, the alarm signal A 102
will appear. The drive will react in accordance with the function set at Parameter 917
(shutdown with ramp, with torque limit/current limit, with controller blocking and
coasting). Once ramp-down has been completed (speed feedback below nmin), the
output is reset for controlling the line contactor. After that, the EM STOP input
should be set back to "1“, the alarm message acknowledged, and the ON/OFF input
likewise be set to "0“. After that, the drive can be started anew.
• Binary input DI7; designation ON/OFF
For connecting the drive to the mains, DI7 must be set to logical "1“. If there are no
ongoing faults, the outputs for controlling the contactors for the armature circuit and
the field circuit will be activated. If DI7 is set to "0“, the controllers will be blocked
internally and the outputs reset after a time-delay.
The function which can be set with Parameter 915 (inputs DI7 and DI8 for switching
the contactors) will only be operative when the drive has been wired as shown
in connection diagram 2.

• Binary input DI8; designation RUN
For starting the drive, DI8 must be set to logical „1“. This enables the reference at the
REF_SEL and RAMP GENERATOR blocks, as well as the controllers. If DI8 is set to
"0“, the drive will react in accordance with the function set at Parameter 916 (shutdown with ramp, with torque limit/current limit, with controller block and coasting).
Once ramp-down has been completed (speed feedback below nmin), the reference is
kept at zero, and the controllers blocked after a time-delay; the drive is torqueless.
Symbols for enabling / disabling the reference

X6: 8 ⇒ „1“ signal
(K21 in connection example)
(input RUN)
- DISABLE reference
X6: 8 ⇒ „0“ signal
(K21 in connection example)

System-dependent planning
If you want the drive to react with a function other than that of Parameter 916 or 917, you
have to parameterize the unit accordingly, by connecting one of the inputs or an additional one with a control pin, e.g. at the ramp-function generator.
- Example 1:
Operational ramp-up and ramp-down in the event of reference changes with the same
ramp times, shutdown via RUN with a different time.
Solution:
use second parameter set ramp times; set time at DECEL2;
establish connection from P 1707 to P 10716.
- Example 2:
Implementing an EMERGENCY SHUTDOWN or EMERGENCY STOP function.
Solution:
this function stipulated in various regulations must always be planned in dependence on
the system involved! A basic distinction must be made here between electrical and mechanical risks. Since one signal at one input is not sufficient (see above), at least one
other switch-off option must be created, e.g. by means of a relay directly switching input DI5 to "0“. This is how the power converter attempts (in accordance with
P 917), to defuse the dangerous situation. A dropout-delay contact of the relay will
then switch the power off. If the delay is small or does not match the function selected
for P 917, then certain operating states (regeneration) may, due to laws of physics,
result in the unit fuses tripping, and in extreme cases in thyristor defects.

2.1 Preparatory work
Check the unit for damage in transit or other damage.
Install and wire unit; connect all inputs and outputs required.
Proceed in the same way for the field supply unit as well.
Check whether protective measures, earthing, screening, etc. have been taken in
accordance with the system conditions involved.
Check the rated value of the supply voltage for the electronics and the fan:
• matching transformer necessary when:
- electronics supply is not equal to 115 V/230 V
- single-phase-fan supply is not equal to 230 V
- three-phase-fan supply is not within the range of 400 V .... 690 V.
Check the rated value of the supply voltage for the armature-circuit converter's
power section; the particulars given on the rating plate must be > than the rated
line voltage.
If this condition is not satisfied, then the following applies:
- use an isolating transformer, or
- use a suitable unit.
Check the rated value of the supply voltage for the field supply unit.
(Particulars on rating plate > rated line voltage?
Is an auxiliary transformer or perhaps a series resistor necessary?)
Check the wiring, fusing, the cross-sectional areas of the cables.
Provide an option for switching binary inputs X6: 7 and X6: 8.
Check the system's EMERGENCY STOP for proper functioning! Set the system-side
monitoring functions, and activate them. Check whether auxiliaries, such as motor fans
or unit fans, function properly; while doing this, also check for correct direction of rotation and voltage level as well!

DANGER: System components now energized!
Please wait a few moments. During this time, the unit compares the phase sequence
set in the parameter with that obtaining at the power section.
If the unit outputs the "Phase sequence fault of power section“ signal (F 38):
- switch off unit completely and disconnect from the mains, interchange two phases at
the input, and start again from the beginning of this chapter.
or
- enter: 506 = R-T-S and then acknowledge fault signal.
Unit will automatically adapt to phase sequence; this signal is to be interpreted as information to the effect that the fans' direction of rotation may be wrong for size-C4

If the unit outputs the "Phase sequence fault of power section“ signal (F 38):
- switch off unit completely and disconnect from the mains, interchange two phases at
the input, and start again from the beginning of this chapter.
or
- enter: 506 = R-T-S and then acknowledge fault signal.
Unit will automatically adapt to phase sequence; this signal is to be interpreted as information to the effect that the fans' direction of rotation may be wrong for size-C4
units.

Chapter 3 - Handling of Control Panel CDP 31x
3.1 Overview
The Control and Display Panel [Control Panel] is used for parameter setting, for feedback value measuring and for drive control with
series DCS 500B / DCF 500B and DCP 500B thyristor power converters. This device is available in different versions depending on
the type of unit and software to be used:
Units with software S 21.1xx
⇒
Units with software S 21.2xx
⇒
CDP 310 or CDP 311
(recommended: CDP 311)
CDP 312
Hereinafter CDP 31x will be used as a common type designation for
the above mentioned versions of Control Panel. Differences between the versions which have to be taken into account with particular functions will be indicated separately!
Panel Link
The CDP 310/311 Control Panel is connected to the drive via
CDI-300 communication bus.This communication bus, which is
based on the RS485 standard, is a common bus protocol for ABB
Drives products.
MODBUS is used as communication bus connecting the CDP 312
Control Panel to the drive. This Control Panel combined with a
Software version S 21.2xx onwards makes it possible to show the
texts on the LCD in different languages.
The selection of language is performed by parameter [P 522].
Note:
The display texts as shown in this chapter correspond
to the default setting of [P 522] ( ⇒ English)!
Mounting the
Panel
The CDP 31x Control Panel can be handled in three different ways:
• Direct mounting on the thyristor power converter; the CDP 31x is
plugged into the moulded part of the cover of the converter and
connected via an adaptor of approx. 45 mm.
• Mounting on the door of the switchgear cabinet using an assembly kit equipped with a connection cable.
• Use of Panel as remote control device with a connection cable.

• The drive is not present on the link. This is the case if the drive
stops communicating.
• The link does not operate because of a hardware malfunction or
a cabling fault.
Action: Disconnect the CDP 31x and connect it again to the
drive. By this means the CDP 31x will be forced to

UPLOAD will copy all parameters and connections, which are different to default, from the RAM memory of the drive to the FPROM
memory of the Control Panel CDP 31x.
Before a DOWNLOAD is started the factory-set values (default values) should be available within the drive´s RAM memory.
Factory-set values are always available in control board memory
and they can be called by means of BACKUPSTOREMODE parameter 11202 [FACTORY_SET_VALUE] or by means of S2 switch
on the control board SDCS-CON-x.
The DOWNLOAD will copy all values stored in the FPROM memory
of the CDP 31x to the RAM memory of the drive. Downloaded
parameters should be saved to the FPROM memory of the control
board SDCS-CON-x. See chapter 3.5"Saving of Parameters to
backup memory" .
Note: For reasons of safety the DOWNLOAD function will only
operate if „LOCAL mode“ of the Control Panel CDP 31x

4.1 Display of status, alarm and fault signals
Categories of signals
and possibilities of
display
The signals (messages) to be available for thyristor power converters series DCS 500B / DCF 500B or DCP 500 are subdivided
into five
categories:
General messages
Starting errors
F
Fault signals
A
Alarm signals
[112 . .]
Status signals through parameters
A seven segment display on the control board SDCS-CON-x of the
thyristor power converters series DCS 500B / DCF 500B or
DCP 500 is used to show general messages, starting errors, fault
and alarm signals. The signals (messages) are displayed as codes.
If the codes consist of several parts, the characters/individual digits
will be indicated for 0.7 sec one after the other, e.g.:
0.7s
⇑
0.7s
0.7s
⇒
⇒
⇐
F 14 = Speed measurement fault
⇓
In addition to this the DCS 500B DCF 500B or DCP 500 combined
with the LCD of the control panel CDP 31x will be able to show the
fault and alarm signals as well as the status signals (selected by
signal numbers [112 . .]) as clear text.
Note:
The languages to be available for display as text depend
on the type of Control Panel and the Software version
( ⇒ Chapter „Handling of Control Panel CDP 31x“).
For subsequent evaluation via binary outputs or serial interfaces the
16 bit informations FAULT WORD1 [11101], FAULT WORD2 [11102]
and FAULT WORD3 [11103] as well as ALARM WORD1 [11104],
ALARM WORD2 [11105] and ALARM WORD3 [11106] contain several
fault and alarm signals as a binary code.
Each fault and alarm signal is coded as an individual error code to
the LATEST FAULT [11106] and LATEST ALARM [11107].

4.4 Fault Signals (F)
The fault signals will be shown on the seven segment display of the
control board SDCS-CON-x as codes F . . as well as on the LCD of
the control panel CDP 31x as clear text.
All fault signals - with the exception of F 17, F 18 and F 44 - can be
reset (after elimination of the faults); F 20 would be self resetting, if
the communication had been re-established before.
For resetting (RESET) of fault signals the following steps are required:
• Switching off the commands ON/OFF and RUN
• Elimination of the faults
• Fault acknowledgement, i.e. resetting (RESET)
a) as described for CDP 31x
or
b) by short-time setting of the command RESET
to high (logical one) via a binary input
(default setting = DI6).
• Depending on the application conditions generate the commands
ON/OFF and RUN once more.
The fault signals will result in switching off the signal [10910] resp. in
stopping the drive (installation-dependent).
If a fault occurs, there will be three different possibilities of reaction (see
column “Remark” in the fault list):
(1) Fault will switch off the signals energizing the main contactor, the field
contactor and the fan contactor.
(2) Fault will switch off the signals energizing the main contactor and the
field contactor.
(3) Fault will switch off at least the signal energizing the main contactor.

4.6 Status Signals
The status of drive functions (autotuning of controllers; saving values) is shown by status signals named 11201 and 11202. The
status of the first and / or the second field exciter, the torque control
sequencing and the current controller is shown by the signals
11203 to 11205.
In case of a drive function, which is started by setting a parameter
to a defined value the status is indicated automatically on the LCD
display of the panel CDP 31x in plain text. The indication will show
the result directly or will cross-reference to the final location.
The status of the field exciter(s), torque control and current controller is updated regularly by the converter software and can be
checked if one of the three signals is selected.
Depending on the tool in use (CDP 31x or CMT tool) the plain text
or a number appears on the display / screen. This number represents a code which is equivalent to the plain text for signal 11201;
for all others it´s a binary coded decimal number (the 16 bit word
with the binary value for each signals is transferred to decimal).
