Safety Information

Persons supervising and performing the electrical

installation or maintenance of a Drive and/or its external

Option Unit must be suitably qualified and competent in

these duties. They should be given the opportunity to

study and if necessary to discuss this User Guide before

work is started.

The voltages present in the Drive and external Option

Units are capable of inflicting a severe electric shock and

may be lethal. The Stop function of the Drive does not

remove dangerous voltages from the terminals of the

Drive and external Option Unit. Mains supplies should be

removed before any servicing work is performed.

The installation instructions should be adhered to. Any

questions or doubt should be referred to the supplier of

the equipment. It is the responsibility of the owner or

user to ensure that the installation of the Drive and

external Option Unit, and the way in which they are

operated and maintained complies with the requirements

of the Health and Safety at Work Act in the United

Kingdom and applicable legislation and regulations and

codes of practice in the UK or elsewhere.

The Drive software may incorporate an optional Auto-

start facility. In order to prevent the risk of injury to

personnel working on or near the motor or its driven

equipment and to prevent potential damage to

equipment, users and operators, all necessary precautions

must be taken if operating the Drive in this mode.

The Stop and Start inputs of the Drive should not be relied

upon to ensure safety of personnel. If a safety hazard

could exist from unexpected starting of the Drive, an

interlock should be installed to prevent the motor being

inadvertently started.

General Information

The manufacturer accepts no liability for any

consequences resulting from inappropriate, negligent or

incorrect installation or adjustment of the optional

operating parameters of the equipment or from

mismatching the Drive with the motor.

The contents of this User Guide are believed to be correct

at the time of printing. In the interests of a commitment

to a policy of continuous development and improvement,

the manufacturer reserves the right to change the

specification of the product or its performance, or the

contents of the User Guide, without notice.

3 Mechanical Installation

3.1 Hazardous areas

The application of variable speed drives may

invalidate the hazardous area certification (Apparatus

Group and Temperature Class) of squirrel cage

induction motors. Approval and certification should

be obtained for the complete installation of motor

and Drive.

3.2 Mounting location

1. Choose a location that is free from excessive

dust, corrosive vapours, gases and all liquids,

including condensation of atmospheric moisture.

2. If condensation is likely to occur when the Drive

is not in use, install an anti-condensation heater.

This heater must be switched off when the Drive

is in use; automatic switching is recommended.

3. Do not locate the Drive in a classified hazardous

area, unless the Drive is installed in an approved

enclosure and the installation is certified.

4. Install the Drive vertically for best flow of

cooling air.

5. Observe the requirements for ambient

temperature if the Drive is to be mounted

directly above any heat generating equipment

(such as another Drive). The Drive has over-

temperature protection which trips the Drive

when the heatsink reaches 90°C (194°F).

6. If the Drive is to be installed directly beneath

other equipment (such as another variable speed

Drive), ensure the Drive does not cause the

ambient temperature requirements of the

equipment to be exceeded.

7. Leave a minimum clearance of 100mm (4in)

above and below the Drive when mounting it

close to other equipment.

8. If the Drive is not supplied in a NEMA 1 case and

when ingress protection higher than IP00 (IEC529)

is required, install the Drive in an enclosure and

ensure its location and means of access conform

to UK or appropriate safety regulations. The

Drive can be surface mounted or through-panel

mounted in a sealed or ventilated enclosure.

3.3 Control Keypad

The Control Keypad is a plug-in unit which can be

detached from the Drive for mounting in a panel.

Holes are required in the panel for the fixing studs and

connector which project from the rear of the Control

Keypad housing. Refer to Figure 3–1.

3.4 Mounting the DC bus choke

A choke (inductor) is required for the DC bus.

For Drives in an IP00 case, the DC bus choke is installed

externally to the Drive. For Drives in a NEMA 1 case,

the DC bus choke is installed internally.

3.5 Installing in a

sealed enclosure

To maintain sufficient cooling of the Drive when it is

installed inside a sealed enclosure, heat generated by

all the equipment in the enclosure must be taken into

account and the enclosure must be of adequate size.

To calculate the minimum acceptable size of

enclosure, use the following procedure.

Calculate the minimum required surface area Ae for

the enclosure from:

(())

kT T

iamb

−−

where:

Aee = Unobstructed heat-conducting area in m2

k = Heat Transmission coefficient of the enclosure

material in Watts/m2/°C

Ti = Maximum permissible operating temperature in

°C of the Drive

Tamb = Maximum external ambient temperature in °C

P = Power in Watts dissipated by all heat sources in

the enclosure

Example

To calculate the size of an enclosure for one CDE 1100

Drive. The following conditions are assumed:

The installation is to conform to IP54, requiring

the CDE Drive to be surface-mounted within a

sealed enclosure.

Only the top, front and two sides of the

enclosure are free to dissipate heat.

The enclosure is made of painted 2mm (3/32 inch)

sheet steel.

Maximum external ambient temperature: 25°C

(77°F).

Drive PWM frequency: 6kHz.

Insert the following values:

P = 440W (from Losses and Efficiency table)

Ti = 50°C (122°F)

Tamb = 25°C (77°F)

k = 5.5 (typical value for painted 2mm (1/16 inch)

sheet steel)

The minimum required heat conducting area is then:

3.6 Installing in a

ventilated enclosure

If a high ingress factor is not required, a ventilated

enclosure may be used. This will be smaller than a

sealed enclosure.

To calculate the minimum required volume of

ventilating air, use the following formula:

3.7 Mounting a DC braking

resistor

Refer to the manufacturer’s instructions for mounting

the DC braking resistor.

Mount the resistor as close as possible to the Drive,

but not in a position where air heated by it could

affect the Drive.

For Drives in an IP00 case, the DC braking resistor

should be installed externally to the Drive. For Drives

in a NEMA 1 case, the DC braking resistor should be

installed internally.

3.8 Motor cooling

When a motor is driven at low speed, its internal

cooling fan becomes less effective. If necessary,

provide it with additional cooling (such as forced

ventilation).

CDE, CDLE Drive 4-1

4 Electrical Installation

Warning

Electric shock risk

The voltages present in the following locations can

cause severe electric shock and may be lethal:

Supply cables

Output cables

Terminals

DC bus choke

Braking circuit

Certain parts of the Drive

If the Drive has been energized, the AC supply must be

isolated at least seven minutes before work may

continue. Refer to Safety Information on the inside

front cover.

4.1 Cables

For the following connections, use 3-core and 4-core

pvc-insulated steel-conduit covered cable with

copper conductors, laid in accordance with defined

conditions:

AC supply to the Drive

Drive to motor

DC bus choke to Drive

Drive to external braking resistor (if used)

Cable sizes must be selected for 100% of the RMS

currents.

This table is only a guide. Refer to local wiring

regulations for the correct size of cables.

* For 75°C (167°F) rated cable you may use the next size smaller.

4.2 Grounding

Ground connections must be made in accordance

with Figure 4–1. Grounding cables must have at least

50% of the current rating of the supply cables.

Use the shortest possible wiring to connect the Drive

to system ground. The system ground must be

connected firmly to a ground point that cannot be

accidentally disconnected.

The impedance of the ground circuit must conform to

the requirements of Health and Safety Regulations

that may apply.

Inspect the grounding circuit at appropriate intervals.

Use screened (conduit-covered) cable to the motor.

Connect the screen to ground at the power

connector on the Drive.

Ground connections on the power input and power

output connectors are connected together in the

Drive, enabling the following connections to be made

through the Drive:

Motor frame ground to system ground

Motor frame ground to the machine ground

The Drives are suitable for grounded-delta installation

without alteration.

4.3 Grounding terminals

The size of external grounding terminals should be

appropriate to the size of the grounding cables.

Drive

Figure 4–1 Power connections

To gain access to the connectors, remove the four

corner screws from the front cover of the Drive and

remove the cover.

Make the following connections using the size of

cable specified in para 4.1 Cables:

AC power to the Drive

Drive to the motor

DC bus choke to the Drive

External braking resistor to the Drive

The AC power should be applied through an isolator

and a fuse or circuit-breaker of the correct rating

(see Chapter 2 Data).

Unusually long cable runs between the Drive and the

motor may give rise to spurious tripping due to the

effect of cable capacitance. As a result, an over-

current fault would be indicated (OIAC). In this case,

output chokes may be required. In difficult cases,

consult the supplier of the Drive.

4.5 DC bus choke

Connect the DC bus choke to terminals L11 and L12 of

the Drive.

4.6 External braking resistor

When an external braking resistor is used, the isolator

must be equipped with an external trip input.

The Drive must be equipped with an optional IN42

Braking Card. Refer to the

IN42

Braking Card User Guide.

4.7 Control Keypad connections

When the Control Keypad is mounted remotely from

the Drive, use screened cable to connect the Control

Keypad to the Drive. (A 9-pin D-type connector is

used.) Connect the cable screen to an external

ground terminal which should be as close to the

Control Keypad as possible.

The connecting cable should have a maximum length

of 1.8m (6ft).

7 Programming Instructions

7.1 Menu structure

The Drive is programmed by entering values into

parameters. The parameters are held in menus that

group the parameters according to their functions.

The first menu is Menu 0Menu 0 which is the User MenuUser Menu.

This contains the basic parameters that may be read

or adjusted for simple applications.

The remaining menus are the Advanced MenusAdvanced Menus.

These contain all the parameters that may be read or

adjusted for advanced applications.

The parameters in Menu 0 are duplicates of certain

parameters in the advanced menus; for example,

parameter p0.13p0.13 is a duplicate of p1.04 p1.04 (Keypad speed

reference).

7.2 Types of parameters

There are two types of parameter, as follows:

Bit parameters

Bit parameters can be set in either of two logic

states and are used as on/off or change-over

switches.

Bit parameters are prefixed with the letter b

(eg. b1..11).

Variable parameters

Variable parameters can be set at a value within a

specified range. They are used to set numerical

values, or to set the positions of switches having

more than two options.

Variable parameters are prefixed with the letter

p (eg. p1..25).

Certain parameters contain character strings instead

of numerical values. The character strings are

displayed on the Control Keypad in place of values.

When these parameters are accessed and edited using

serial communications, a numerical equivalent is

displayed on the host computer. The numerical

equivalent is used for programming these parameters.

Refer to Chapter 11 Serial Communications.

These operating instructions are based on the Drive

being in StatusStatus mode. (When AC power is applied to

the Drive, the display is automatically in Status

mode.)

Note

If the behaviour of the display does not appear as

described in the operating instructions, refer to

Chapter 10 Security.

10 Security

Security operates at two levels to prevent

unauthorized editing of parameters:

Standard Security

When locked, Standard Security prevents reading

and editing of all the parameters in the

Advanced Menus, , but allows reading and

editing of the parameters in the User Menu

(Menu 0).

A fixed code number is used to unlock Standard

Security.

User Security

User Security operates only when it has been

set-up by the user. When locked, it prevents

editing of all parameters in all the menus except

for the following parameters:

• Parameters p0.13 / p1.04

(Keypad speed reference)

• Parameter 00 in the selected menu

(eg. 07.00). This is used to unlock Security.

The code number used to unlock User Security is

defined by the user. This gives protection

against unauthorized editing of parameters. The

code number can be read and edited only when

User Security has been unlocked.

When AC power is applied to the Drive, Standard

Security and User Security (when set-up) are

automatically locked.

10.1 Unlocking Standard Security

When AC power is applied to the Drive, Standard

Security is automatically locked. Only the parameters

in Menu 0 can be displayed on the Control Keypad for

Standard Security must first be unlocked. Use the

following procedure to unlock Standard Security.

1. Select parameter 00.00.

2. Press

3. Set the value at 149.

4. Press

All the parameters can then be read and edited unless

User Security has been set.

10.2 Unlocking User Security

When User Security has been set-up and AC power is

applied to the Drive, User Security is automatically

locked. Except for parameters 00.00 in each menu,

and p0.13 / p1.04, no parameters can be edited.

Use the following procedure to unlock User Security:

1. Select a menu. Parameter xx.00 in the selected

menu is displayed.

2. Press

3. Set the value at the required number for User

Security. (See Setting-up User Security.)

Ramp modes

The Ramp Modes parameter p2.02 controls

deceleration ramps only. The settings are as follows:

Setting

Description

Std.H Standard-hold

FAST Fast

Std.C Standard-controlled

Mode 0 — Standard-hold mode

In Standard-hold mode, deceleration occurs in steps.

The control causes the deceleration ramp to be

‘frozen’ when the DC bus voltage rises above the

standard ramp voltage (set in p2.28). When the

voltage drops below the Standard-ramp voltage, the

ramp again begins to fall. Although this type of

control does not usually give smooth deceleration

especially if the motor is lightly loaded, it is easy to

set up. A high voltage of AC supply could cause the

Drive to trip on over-voltage due to transients that

could be produced in the Standard-hold mode.

Mode 1 — Fast mode

The ramp falls at the programmed deceleration rate

subject only to the current limits programmed.

This mode is normally used when a braking resistor is used.

The dynamic break becomes active at a DC bus level of 780V

Mode 2 — Standard-controlled mode

The PID controller is used to modify the ramp so that

the DC bus voltage is held at the Standard-ramp

voltage (set in p2.28). This gives smoother control

than Standard-hold mode, but it may be necessary to

use an oscilloscope to set up the PI gains.

Care should be taken in choosing the Standard-ramp

voltage (using p2.28), because, if this is lower than

the nominal DC bus voltage produced by the AC

supply, the DC bus controller will accelerate the

motor up to the maximum frequency (set in p1.06) in

an attempt to reduce the DC bus voltage.

See p2.28 — Standard ramp voltage.

The Standard-controlled mode is useful in

applications where smooth deceleration is required,

particularly with lightly-loaded machines, or where

the AC supply voltage is high.

Caution

The D term operates in Standard-controlled

mode and under AC supply loss. Care must be

taken not to have instability in either case

due to an excessively high gain

p2.03 Acceleration ramp 1 R–W

Range 0.1 to 3276

s/100Hz

Default 5

Acceleration ramp rate is expressed as the time for

the output frequency to increase by 100Hz.

For example, a programmed ramp time of 5 seconds

causes the frequency to increase or decrease by 50Hz

in 2.5 seconds.

p2.04 Deceleration ramp 1 R–W

Range 0.1 to 3276

Deceleration ramp rate is expressed as the time for

the output frequency to decrease by 100Hz.

Range 0 to 800 V Default 700 (EUR)

775 (USA)

390

(CDLE)

This parameter is used for Standard-hold and

Standard-controlled modes.

The minimum level for the Standard-ramp voltage

should be greater than the voltage produced on the

DC bus by the highest AC supply voltage (normally

RMS AC supply voltage x √2).

When Standard-hold mode is used and the Standard-

ramp voltage is set too low, the Drive will not stop.

If the Standard-ramp voltage is set too high and no

braking resistor is used, the Drive may trip on over-

voltage.

When Standard-controlled mode is used and the

voltage is set too low, the motor will accelerate to

maximum frequency. (AC supply loss uses a fixed

control voltage that is dependent on the voltage

rating of the Drive.)

p2.29 Proportional gain R–W

Range 0 to 99.99

Default 1.00

Enter a value of proportional gain for the PID

This is used to control the DC bus voltage during

Standard-ramp deceleration and loss of AC supply.

Default 4.00

Enter a value of integral gain for the PID controller.

This is used to control the DC bus voltage during

p2.31 Derivative gain R–W

Range 0 to 99.99

max.

Default 0.00

Enter a value of Derivative gain for the PID controller.

This is used to control the DC bus voltage during

Standard-ramp deceleration and loss of AC supply.

The D term operates in Standard-controlled mode and

under AC supply loss. Care must be taken not to allow

instability in either case due to an excessively high gain.

p2.32 S-Ramp band R–W

Range 0 to p1.06p1.06

Default 0

Enter a value to define the frequency band for the

curve at each end of the S-ramp. Time taken for

acceleration or deceleration on the curve is double

that for a straight ramp.

If the ramp time changes during a change of speed,

the S-ramp does not give stepless acceleration or

deceleration. For example:

If different ramp rates are used for acceleration

and deceleration, and the Drive passes through

zero speed.

If the ramp rates are changed using the

acceleration or deceleration select bits.

Frequency slaving

When used in a frequency-slaving system, the Drive

can be set up as a Master, Slave or both. Frequency-

slaving, parameter b3.04 should be set at 0 to select

x192 frequency ratio.

When a Drive is not required to operate as a Slave, the

If p3.07 is changed while the Drive is running,

frequency locking between the Drives will not be

It is good practice to stop the Drive first.

It is recommended to keep p3.07 at the default

Refer to the example on the previous page for

b3.08 Enable quadrature input R–W

Range 0 or 1 Default 0

Set at 1 to enable encoder quadrature input.

This is not available when p3.03 or p3.05 are set at 1.

Quadrature input is not available if frequency output

is required, since the B channel encoder input shares

terminals with the frequency output.

The pulse-train frequency can be monitored by the

Drive, and the measured frequency used to derive the

frequency demand for the Drive. In either case,

parameters p3.06 and p3.07 (frequency input ratio)

must be set up to scale the input measurement so

that read-only parameter p3.01 indicates 100.0%

when maximum input frequency is demanded.

The following equations should be used to calculate

the scale factor required for different motor speeds

and encoder lines:

(RPM = maximum motor speed

N = Number of encoder lines)

Encoder with Quadrature

Counting enabled

Scale = 464 916

RPM N××

Encoder without Quadrature Counting

(no direction information)

Scale = 929 832

RPM N××

Scale = 15 497

Fmax

It is recommended that parameter p3.07 is left at its

default value of 1.000 and the result of the above

calculations entered into parameter p3.06. If the

result of the calculation is very low, the difference in

top speed values becomes very coarse. If this occurs,

adjust p3.07 to finely tune the maximum measured

input frequency.

Example

A 2048 quadrature encoder is fitted to a 3000 RPM

motor

Scale =

464 916

3000 2048 007567

×× == .

Only 0.075 can be entered in parameter p3.06. This

value equates to a maximum speed of 3027 RPM.

A value for parameter p3.07 can be calculated as

follows:

p3.07 = p

Scale

306 0075

0 07567 0991

..====

Parameter p3.01 can then be used either as an input

to the PID software or a MD29 application program. If

parameter b3.09 is set at 1, p3.01 can be used as a

frequency reference for the Drive. In this case the

100.0% maximum in parameter p3.01 is automatically

scaled to give maximum frequency reference (p1.06)

in the Control Keypad reference parameter.

CDE, CDLE Drive

11-14

Resolution

When the frequency reference input is used to control

frequency demand (ie. slaving is not being used), the

resolution of the reference is dependent on the

maximum input frequency. It is not possible to

obtain a higher resolution than 0.03Hz or a resolution

from 0 to maximum frequency of greater than 1/4000

(or 0.025%). Subject to these limits, the resolution

may be improved with higher quadrature count rates.

Since the input pulses are counted over a gate period

of 16.132ms, the resolution can be calculated using the

following equations:

Encoder with Quadrature

Resolution = 92 983 2. %

Peak limit

The peak limit prevents transient peaks in motor

current (torque-producing and magnetizing) from

exceeding a specific level.

The Drive accomodates transient peaks in current by

modifying the output voltage. This occurs only when

the output voltage is below the maximum for the

Drive.

The maximum RMS value of a sinusoidal output

current that should occur with the peak limit

operating is given by:

OIAC x (2000 / 2660) ÷ √2

(This is approximately 1.5 times the maximum current

limit for the Drive).

Normal current limit

The normal current limit modifies the output

frequency of the Drive in order to control the output

current level. This operates at a lower level than the

peak limit and is not as fast as the peak limit.

When the Drive is operating correctly, the normal

current limit should normally be sufficient to control

the Drive current, and the peak limit should rarely

operate.

The maximum current limit is defined in parameter

p11.35. The normal current limit controls only the

torque-producing current in the motor and not the

magnetizing current.

Rated torque-producing current

This is nominally the motor rated current × cosφ. The

Drive can deliver a torque-producing current of 1.2 or

1.5 times the rated level before the normal current

limit operates.

In torque-control mode, the torque produced by the

motor is controlled by modification of the Drive

output frequency using the PI controller. This

controller uses the same P and I terms as the current

limits set in parameters p4.08 and p4.09.

Below rated frequency, the torque demand is

converted to torque-producing current.

Above rated frequency, the current is increased (to a

reduction of flux in the motor.

p4.06 is subject to normal current limits.

cause a larger change in torque-producing current for

a given change of frequency.

defined in p4.08 and p4.09.

It is possible to change between torque control and

frequency control when the Drive is running without

causing transient frequency changes.

The current limits operate when torque-producing

current is above the current limits entered in p4.04

The PI controller attempts to change the output

frequency to reduce torque-producing current. If a

motoring load overloads the motor, it will stall. If the

motor is overloaded with a regenerative load, it will

accelerate to maximum frequency.

The ramp time will have an effect. The gains of the PI

controller must be sufficiently high to cancel the

higher gains.

Normally, only the P term is necessary for satisfactory

operation.

Symetrical current limit works in Motoring and

After having set the required value of maximum

percentage overload current using p4.11. The

maximum percentage that can be set is limited by the

overload current rating of the Drive. The limit applies

when motoring and regenerating.

p5.06 Motor rated current R–W

Range 0 to p11.33p11.33 A Default 11.33

Parameters p5.06 (motor rated current) and p5.13

(power factor) are used by the Drive to determine the

rated torque producing current (itorq rated) for the Drive.

When parameter p5.06 is set at a value lower than the

default rating of the Drive, the maximum current of the

Drive can be greater than 1.5 times the motor rating.

Consequently, the maximum value of current limit and

torque parameters (p4.04, p4.05, p4.06, p4.11,and

p6.04) can be increased proportionately.

For example, if a 110 Amp Drive has parameter p5.06 set

at 55 Amps, the maximum values of parameters p4.04,

p4.05, p4.11 and p6.04 can be 300% (2 × 150%). This

allows larger Drives to be used for a high starting torque.

When the value is increased beyond the default value of

p5.06, the value of p4.11 is automatically decreased.

Itorque = p5.06 x p5.13

The value entered affects the following:

Slip compensation

Dynamic V/f

Ixt detection level

Industrial and HVAC applications

Industrial applications benefit from a higher

percentage of overload current, but have a lower

nominal current. HVAC applications benefit from a

higher nominal current, but have a lower percentage

of overload current (typically 120%). The overload

current has the same value in each case.

See parameter p5.18.

p5.07 Motor rated RPM at full load R–W

Range 0 to 9999 rpm Default 0

Enter the value from the motor rating plate. This is

used by the Drive to apply correct slip compensation.

If no slip compensation is required, set p5.07 at 0

(default).

p5.08 Motor rated voltage R–W

Range 100 to 480 VRMS Default 400 (EUR)

240

(CDLE)

460 (USA)

Enter the value from the motor rating plate in order

to define the maximum output voltage of the Drive.

Parameter p5.08 must be programmed with the value

given on the motor rating plate. This informs the

Drive of the maximum voltage that should be applied to

the motor.

The Drive controls the output voltage to give a linear

voltage-to-frequency characteristic from 0Hz to the

motor rated frequency, and from 0V to the motor

rated voltage. (This characteristic can be modified

by voltage boost or stator resistance compensation.)

Since the Drive compensates for variations in DC bus

voltage, the resulting voltage from the voltage-to-

frequency characteristics does not change with DC

bus voltage (ie. there is no change when the Drive is

braking).

Note that, even with a perfect supply, it is not

possible to obtain an output voltage greater than the

supply voltage when motoring.

When the required voltage exceeds the maximum

possible output level (dependent on the supply) or

the rated voltage (set by the user), the frequency can

still be increased, but the motor enters the

constant-power or field-weakening region.

Whatever value of motor rated voltage is entered,

the Drive output will contain high frequency

switching components having peak voltage levels

related to the DC bus voltage level, not to the motor

rated voltage. Consequently, when a motor of low

voltage is used, the high-frequency switching

components at the Drive output may stress the

windings.

p5.09 Motor rated frequency R–W

Range 10.0 to 999.9

Above 25% of rated frequency, a linear voltage-to-

frequency characteristic normally produces sufficient

torque. Below this frequency, voltage boost may be

required in order to maintain the torque.

The voltage control mode selector is used to select

the required type of voltage boost at low

frequencies and the conditions for measuring stator

resistance.

Mode 0 — Auto boost

Auto boost automatically controls the voltage boost

with load. If the level is set too high, the motor can

become over-fluxed, and the boost can become

‘latched’ at a high level.

With high inertia loads at low speed, the Drive may

trip when decelerating the motor to a stop. This will

result in the motor coasting to a stop.

The level of boost is determined from the value in

parameter p5.11 (voltage boost) which is then

modified so that:

Auto boost = Voltage boost × itorq / itorq rated

Mode 1 — Fixed boost

Fixed boost can give high levels of current when

starting and stopping, but can result in over-fluxing of

the motor on light loads.

Mode 2 —

Vector mode with stator resistance

measurement at start

Mode 3 —

Vector mode with stator resistance

measurement at power up

Mode 4 —

Vector mode with no stator resistance

measurement

Vector mode is intended for operation with a single

motor and gives reasonable control of the motor flux

with different loads, since the voltage-to-frequency

characteristic is modified according to the load

inertia. (Closed-loop current control is not used.)

The voltage-to-frequency characteristic is based on

the following motor parameters:

Magnetizing current

Stator resistance

Good control of the magnetizing current (and hence

motor flux) extends down to:

Rated frequency ÷ 50

(ie. value of parameter p5.09 ÷ 50)

The parameters required for this mode can be derived by

the Drive during the magnetizing current measurement.

Measuring stator resistance

This measurement can be performed

automatically under the following conditions:

• When AC power is connected to the Drive

(Ur_I mode)

• When a START command is given to the Drive

(Ur_S mode)

The second condition (Ur_S) is recommended

because stator resistance can change with

temperature.

The measured value is stored in parameter p5.15,

along with a voltage offset related to the IGBT

voltage drops and other effects in the Drive

(p5.17).

When AC power is disconnected from the Drive, the

power factor and stator resistance are automatically

stored.

When Ur_I mode is selected, the voltage is based on

previously measured values (in Ur_I mode, the stator

resistance is not measured). The voltage offset (which is

usually quite small) is not saved when AC power is

removed, so this fine correction of the voltage applies

only when Ur_S or Ur_I modes are used.

CDE, CDLE Drive 11-23

Note

The results of the stator resistance

measurement (but not the magnetizing

current measurement) are to some extent

dependent on the switching frequency and

modulation technique being used. Good

control at low speed can be maintained only

when the switching frequency and space

vector modulation (see Menu 6) are not

changed after the stator resistance has been

measured.

Measuring the magnetizing current

Warning

The motor runs at half maximum speed while

this measurement is performed.

This measurement can be carried out with the

motor on- or off-load. If the measurement is to be

carried out on-load, a reasonable estimate of the

power factor of the motor (which relates to the

magnetisng current) must first be given to the

Drive. In most cases, the default value will be

sufficiently close to that of the motor. If it is not,

enter in parameter p5.13 the figure for the power

factor of the motor.

Use the following procedure:

1. Ensure the Drive is stopped.

2. Set p5.16 at 255.

3. Ensure that a trip is not active.

4. Apply a continuous signal to the STOP input

(Do not activate the START input).

5. Press the STOP–RESET button or apply a

momentary signal to the RESET input

(pin 4 of CON 3) to reset the Drive.

Note

The measurement should now be carried out.

If it is not carried out (eg. because the STOP

input is not active) the measurement is

cancelled. To try again, repeat the

preceeding instructions.

6. The power factor parameter p5.13 is now

updated with the value calculated during the

measurement.

Ensure the stop switch is closed.

Set 5.16 at 255 to start the test.

Reset the Drive to enter the new value of power

function in p5.13.

Default 60

Enter a value for the required duration of maximum

overload current.

When the Drive is used with motors having a relatively

low power rating, the motor could be damaged by the

overload current of the Drive. To protect such motors,

the value of parameter p5.18 can be reduced to reduce

the time that the overload current is produced. The

default value of p5.18 is 60 seconds.

Parameter p6.01 controls the stopping mode.

Stopping occurs in two phases, as follows:

Phase 1: Decelerating to stop

Phase 2: Drive stopped

The settings are as follows:

Mode [0] — Ramp mode

The Drive ramps to zero speed during the first phase,

and then waits for one second in the second phase to

ensure the motor has completely stopped before

disabling the output.

Mode [1] — Inhibit mode

The output is disabled as soon as a STOP command is

received, and the motor coasts to rest. The first phase

consists of a two-second delay before the Drive can be

restarted. There is no activity in the second phase.

Mode [2] — DC injection braking

Mode [3] — Ramp plus DC injection

braking

Mode [4] — Timed DC injection braking

In all these modes, the second phase consists of injection

of DC current for at least one second at the level entered

in parameter p6.04. This ensures the motor is

completely at rest before the Drive output is disabled.

The first phase of Mode [3] is the same as that for

Mode [0].

In Modes [2 ]and [4], injection braking uses low-

frequency current at a level programmed in parameter

p6.04 during the deceleration phase. In Mode [2]

this allows the Drive to detect when the motor has

reached a low speed, so the injection time is adjusted

automatically to suit the motor and the load. In

Mode [4], the time for decelerating to a stop must be

programmed in parameter p6.05.

In Mode [2] only, when a stop is initiated, the Drive

monitors the motor to detect when the speed reaches

5Hz so phase 2 can be initiated. If the injection

current is too low, the detection system does not

operate and the motor rotates continuously at a low

frequency.

The minimum level of current required is normally

between 70% and 80% of the rated current of the

motor.

Once stopping in Mode [2] or [4] has begun, it can be

terminated by the motor stopping, or the occurrence

of a trip. In this case, the Drive must be stopped

before it can be re-started.

diS [0] The Drive does not start when AC

The Auto-start modes define the behaviour of the

Drive when AC power is applied.

Mode [0] — Disabled

The Drive will not automatically start when AC power

is applied.

Mode [1] — Always

The Drive always starts irrespective of the state

before AC power was removed. The STOP input

switch must be closed.

Mode [2] — Power-down dependent

The Drive starts only if it had been running when

AC power was removed. The STOP input switch must

be closed.

p6.03 AC supply loss mode R–W

Range [0] to [2] Default rd.th [2]

dis [0] Disabled

Stop [1] Stop when AC supply is lost

rd.th [2] Ride-through short interruptions

The AC supply loss modes are as follows:

Mode [0] — Disabled

Loss of AC power is not detected. The Drive

continues to operate unchanged only while the DC bus

remains within specification. When the voltage is

below specification, the Drive ceases to control the

motor.

Mode [1] — Stop mode

Mode [2] — Ride-through mode

When loss of AC power is detected, the Drive

decelerates at a rate to return sufficient power from

the motor to the DC bus in order to supply the control

circuits. Since the PID loop for the Standard-

controlled ramp (see parameter p2.02) is used for

this function, adjustment of the PID gains (p2.29 to

p2.31) may be necessary for the feature to operate

correctly. In this case, the PID controller attempts to

force the DC bus voltage to 700V for the CDE models

(380V for the CDLE models) and then hold it constant

by changing the Drive output frequency.

Normally, the DC bus voltage can be held at a fixed

level with a PI controller. If the motor is heavily

loaded when AC power is lost, the frequency must be

reduced quickly to prevent the DC bus voltage from

reducing below specification.

The D term will operate for 250ms after loss of AC

power in order to improve the response. The D term

is stopped after this point, since it can make the

control loop unstable if it continues in operation.

The ramp rate is controlled by the PID controller, and

is at least as fast as the deceleration ramp for a

normal stop.

In order to help reduce the frequency quickly, slip

compensation is disabled when loss of AC power is

detected (this will have no effect if no slip

compensation has been programmed).

When AC power is restored and Stop mode is

selected, the Drive continues to decelerate until the

machine stops. When Ride-through mode is selected,

the motor accelerates to its normal running speed.

vector modulation

R–W

Range 0 or 1 Default 0

Set at 1 for high-stability space vector modulation.

This is a special case of space vector modulation

which results in each phase being clamped to one or

other of the DC bus rails in the Drive for 1/6th of a cycle

of the fundamental output. This gives the following

advantages:

Lightly-loaded 50Hz induction motors supplied

by variable speed drives can go unstable at

frequencies between 10Hz and 30Hz. High-

stability space vector modulation prevents this

instability.

At the transition to pulse-dropping (see b6.21),

instability can be caused especially on lightly-

loaded machines. High-stability space vector

modulation reduces this effect.

High-stability space vector modulation has the

disadvantage that unwanted voltage components

result in more acoustic noise than when using other

techniques.

For normal and high-stability types of modulation,

dead-time compensation is used. This should help to

reduce instability when normal space vector

modulation is used in the 10Hz to 30Hz range.

above the motor rated voltage. The Drive becomes

over-modulated until pulse-dropping occurs and a

square-wave is produced. The resultant harmonics

can produce high peak currents and cause high levels

of acoustic noise in the motor.

b6.22 Disable forward rotation R–W

Range 0 or 1 Default 0

Set at 1 to prevent the Drive producing forward

rotation of the motor (except when frequency

slaving).

b6.23 Disable reverse rotation R–W

Range 0 or 1 Default 0

Set at 1 to prevent the Drive producing reverse

rotation of the motor (except when frequency

slaving).

CDE, CDLE Drive

11-28

b6.24 Catch spinning motor R–W

Range 0 or 1 Default 0

Set b b6.24 at 1 to select this feature.

The Drive performs a sequence of tests to determine

the motor frequency before attempting to apply full

voltage to the motor. To limit the motor current, the

tests are carried out at a reduced voltage set in

p6.34 of the required voltage.

The Drive frequency is first set at maximum (set in

p1.06) in the direction in which the Drive last ran.

The frequency is then ramped to zero over a peroid

entered in p6.33 and compared with the motor

frequency.

If the motor frequency is not detected, the frequency

is set at maximum in the other direction and the test

is repeated. When the frequency is detected, the test

is stopped and the Drive starts at the detected

frequency and takes control of the motor.

If the motor frequency is not detected at all, the

Drive starts at 0Hz.

If the Drive is powered-down, the previous direction

of rotation is not stored, so the test begins in the

forward direction.

p6.25 Enable motorized

potentiometer zero start

R–W

Range 0 or 1 Default 0

When p6.25 is set at 1, and AC power is applied to the

Drive, the motorized potentiometer output is set at

zero.

When p6.25 is set at 0, and AC power is applied to

the Drive, the motorized potentiometer output

returns to the level that existed when AC power was

previously removed.

p6.26 Motorized potentiometer

R–W

Range 0.00 to 17.50 Default 0

Reset the Drive to make active.

Program the destination parameter that the

motorized potentiometer is to control. If the

motorized potentiometer is to control speed, it is

suggested that one of the preset speed parameters is

entered in p6.31. If the motorized potentiometer is

to trim speed, it is suggested that p1.15 (offset

parameter) is entered in p6.31.

p6.32 Motorized potentiometer

output

Range ±100.00 % Default

Saved at power down.

This parameter indicates the current level of the

motorized potentiometer. The value is saved when

AC power is removed from the Drive.

p6.33 Spin start ramp time R–W

Range 2.0 to 25.5

secs

Default 10

Time taken to ramp down from maximum frequency

(p1.06) to 0 Hz while the Drive attempts to

synchronize itself with a spinning motor. Change the

value for applications that require the Drive to be

caught in a shorter or longer time.

p6.34 Spinning motor scan voltage R–W

Range 0 to 100

Default 25

When the Drive is in normal operation, the rated

motor voltage varies with frequency. When the Drive

is attempting to synchronize itself to a spinning

motor, a percentage of this varying voltage is applied

to the motor. The value entered in parameter p6.34

determines this percentage.

If the value is too low, the motor may not be

detected during the scan. If the value is too high, the

Drive may trip on OIAC or OV.

every time the Drive trips, regardless of auto-resets.

Set at 1 for the Drive normal indication to remain

set when a trip occurs and an auto-reset is going to

occur.

b10.29 External trip R–W

Range 0 or 1 Default 1

When an external trip signal is required to control this

parameter, use a programmable digital input and

ensure that the input state is at logic 1 to prevent the

Drive tripping.

When b10.29 = 0 the Drive will trip.

CDE, CDLE Drive 11-41

p10.30 Processor 2 trip R–W

Range 0 to 70 Default 0

When a user-defined trip occurs and causes a

command from an expansion card or serial

communications to be sent to the Drive, parameter

p10.30 can be used to trip the Drive and display a

relevant trip code.

The expansion card should enter a valid trip code into

p10.30. Valid codes are 40 to 69. The display will

then show tr40 to tr69 accordingly. The Trip log

will also show these codes.

If a standard Trip code is entered in p10.30, the Trip

code will be shown and the Drive tripped accordingly.

The Drive can be reset by setting p10.30 at 70.

The inputs to the PID controller are automatically

scaled to the range ±100.0%. The PID controller

output is also within this range.

Although it would appear that the variables have only

10-bit resolution, internal calculations are made at a

higher resolution for greater accuracy. The displayed

values are scaled versions of the internal variables.

After the final addition to the main reference, the

output is automatically scaled again to match the

12 Serial Communications

12.1 Introduction

Serial communications can be used by a host

computer or PLC to perform the following:

Read and edit the values of parameters

Control the Drive

One host computer may control up to 81 Drives when

line buffers are used or 32 Drives without line buffers.

The serial communications format is RS485 which is a

differential link that ensures a high level of immunity

to noise. It also withstands high common-mode

rejection. The protocol is the following industry

standard:

ANSI x 3.28 − 2.5 − A4

The data format is as follows:

7 data bits

1 start bit

1 stop bit

Even parity

12.2 Connecting the Drive

Two- wire or four-wire mode may be used (refer to

Figure 12–1).For best reliability use screened twisted

pair cable.

Connections for 4-wire mode

Connections for 2-wire mode

Serial address code

Each Drive on a serial communications link, must have

an individual address code. The required serial

address code should be entered in p11.23. The code

must have two digits, and the number 0 must not be

used. The first digit defines the group (1 to 9); the

second digit defines the Drive number in the group

(1 to 9).

The code for an individual Drive should be sent by the

host as in this example:

Drive address code: 2 8

Address code to be sent by host: 2 2 8 8

To address all the Drives in Group 2, the host would

need to send:

2 2 0 0

To address all Drives on the serial comms link, the

host would need to send:

0 0 0 0

Parameter identifier

To address an individual parameter, the host needs to

send a code that relates to the parameter number.

For example:

To address: p0.01

Send: 0001

Data field

Data are sent as numerical values with a negative

polarity sign and decimal point when appropriate.

The data field is of variable length, with a maximum

of seven characters including the decimal point. The

state of bit parameters is sent as numerical value 1 or

0 . For variable (p) parameters, having a series of

options defined by character strings on the display

(eg. p7.10), the first option (std.H = 0) is set by

sending 0, the second option (Fast = 1) by sending 1,

etc.

Block checksum

The block checksum character (BCC) is used to check

that each message has not been corrupted when

being sent. The BCC is a value that is calculated from

the ASCII codes of the characters in the parameter and

data fields.

The following example shows how the BCC is

calculated.

A message for parameter p1.25 contains the value −−

47.6. The parameter identifier is 0125 and the data

field contains −−47.6.

The Binary codes (for the parameter identifier) are as

follows:

0011 0000

0011 0001

0011 0010

0011 0101

The first and second ASCII codes are compared in an

XOR function. The result is 0000 0001.

This result is compared with the third ASCII code

(0011 0010) which produces the result 0011 0011.

This number is then compared with the next ASCII

code. The process is repeated until the final digit in

the data field is reached, as shown below:

Character

Binary code XOR

011 0000

011 0001 0000 0001

011 0010 0011 0011

011 0101 0000 0110

−

010 1101 0010 1011

011 0100 0001 1111

011 0111 0010 1000

010 1110 0000 0110

011 0110 0011 0000

ETX

000 0011 0011 0011

011 0011

Note

If the decimal value is less than 32, then 32 must be

added. The resulting code is then used to derive the

BCC.

Messages from host to Drive

Messages from the host to the Drive are used to:

Interrogate the Drive for values or states of

parameters

Send a command to the Drive

CDE, CDLE Drive 12-3

12.4 Interrogate the Drive

To find the value of a parameter, the host should send

a message that is structured as shown below.

The data field is not used. The final control character

should be: ENQ (Ctrl E)

12.5 Send a command

to the Drive

Commands are used to:

Change the value of a parameter

Control the operation of the Drive

To send a command, the message structure shown

below should be used.

Figure 12–4 Sending a command to the Drive

12.6 Change a parameter value

To change a parameter, the message should contain

the relevant parameter identifier. The data field

should contain the required value.

For example, to set parameter p1.25 at −−47.6Hz,

send:

Parameter identifier 0125

Data field −−47.6

To set b1.10 at 1, send:

Parameter identifier 0110

Data field 1

12.7 Control the Drive

To control the Drive using serial communications, no

input terminals should be programmed to control the

sequencing bits (b6.08 to b6.11). They should be

programmed using serial communications. It is

suggested that Sequencing mode 3 3 (PLC interface)

is used for this.

To control operation of the Drive, the message should

contain the relevant control parameter identifier.

The data field should contain the value relating to the

required control state. For example, to start the

Drive, b6.08 must be set at 1.

Send:

Parameter identifier 0608

Data field 1

To stop the Drive, send:

Parameter identifier 0608

Data field 0

12.8 Messages from Drive to host

Messages from the Drive to the host are used to:

Reply to an interrogation (send a message

containing the value of the parameter specified

by the host)

Acknowledge a command from the host

12.9 Reply to an interrogation

When the Drive is interrogated for the value of a

parameter, the Drive sends a message in reply that

contains the parameter identifier and, in the data

field, the value of the parameter.

The structure of reply messages is shown opposite.

12.10 Acknowledge a command

When a message has been sent by the host, the Drive

responds by sending an acknowledgement.

If the message was a command, the Drive sends the

reply message: ACK

If a command from the host is not understood, the

Drive sends the reply message: NAK

A message can be misunderstood because:

Transmission was corrupted

Message was incorrectly structured

Requested value was out of range

If the specified parameter number is not recognised

by the Drive, the Drive sends the reply message: EOT

Time can be saved by sending the control codes given

below:

NAK (Ctrl U) Repeat enquiry Interrogate the Drive repeatedly

for the current value of the last

specified parameter.

ACK (Ctrl F) Next parameter Interrogate the Drive for the

value of the next parameter in

the list.

BS (Ctrl H) Previous

parameter Interrogate the Drive for the

value of the previous parameter

in the list.

To ensure that the correct Drive answers, a valid full-

length read or write must occur before these codes

will work.
