Product Range

The AC890PX AC Drive is designed to control 3-phase induction or permanent magnet AC
motors, or to be used as an active front-end.

Designed as a free-standing drive, the AC890PX comprises removable modules housed in a tall
cabinet.

It is available in a range of ratings for constant torque and variable torque applications. This
dual mode feature provides a cost effective solution to general industrial applications, as well
as the control of pumps and fans.

• Supplied as a top or bottom wire entry version.

• Local control is achieved using the Keypad.

• Remote control is via the DSE 890 Configuration Tool. This gives access to parameters,

diagnostic messages, trip settings and full application programming. Other features also
become available, such as the advanced sensorless vector control scheme which gives high
torque, low speed operation; and a unique Quiet Pattern control system that minimises
audible noise from the motor.

IMPORTANT

NOTE Do not attempt to control motors whose rated current is less than 25% of the drive rated

• The unit can also be controlled remotely using configurable analogue and digital inputs and

outputs, requiring no optional equipment.

• Option Cards can be fitted to the drive to give serial communications, closed loop speed

control, and the factory-fitted dynamic braking functions.

OUTLET AIR

Substantial heat is dissipated (refer to Appendix E: “Technical Specifications” –
Electrical Ratings, for Total Power Loss) and therefore sufficient volume for exhaust
venting is required to keep the drive from raising the operating temperature beyond
that specified in the Environmental Specification.

Maintain a 100cm air clearance at the front (air vent and filters) and top of the drive
(air vent). It is possible to turn the top air vent through 180°, in which case air
clearance must be maintained at the rear of the drive also. Air clearances are not
required on the remaining surfaces of the drive.

Ensure that heat generated by other adjacent equipment is not transmitted to the drive.
Be aware that other equipment may have its own clearance requirements.

2.1.5 External Brake Resistor (J)

The AC890PX is fitted with an internal resistor. Removing the internal brake resistor connections will disconnect the internal
braking resistor allowing the connection of an external brake resistor.

NOTE It is possible to use both the internal and external brake resistors (wired as shown) but we recommend you contact

Parker SSD Drives for advice.

Refer to Chapter 4: "Associated Equipment" - External Braking Resistors for help with using and selecting external brake
resistors.

The overload relay protects the internal brake resistor. The switch will require resetting to "ON" if the drive trips on BRAKE
SWITCH (the keypad display).

There are similar trips to protect the external brake resistor. Refer to Chapter 8: "Trips and Fault Finding".

2.1.6 Blower Motor Thermal Overload Protection (G)

The drive provides a 3-phase supply for the motor fan.

The overload relay switches the power on/off. The switch, rated at 4-6A, is adjusted to trip if the motor fan draws more than
5A. In the event of a trip, the switch will require resetting to ON.

2.1.7 Auxiliary Transformer Taps (C)

The transformer is tapped for no connection, i.e. 0V - PARK when
it leaves the factory and the drive will not operate. Either a low
voltage or high voltage transformer option is fitted to the drive.

Match the auxiliary transformer tap to the drive's nominal supply
voltage. For example, connect the taps to 0V and 400V for a
nominal supply voltage of 400Vac.

The transformer supplies a constant 30Vac to the Control Module,
internal fans etc. It is protected by a 40A semi-conductor fuse

2.2: Control Connections

p

During commissioning, remove the fuses (or trip the circuit breaker) on your 3-phase supply.

Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.

Allow at least 10 minutes for the drive's capacitors to discharge to safe voltage levels (<50V).

Main Points

♦ The control connections are made to the Control Module. (Where the drive is a bottom wire entry version, the control

terminals are brought out to a second set of terminal blocks in the bottom of the drive).

♦ The control terminals will accept a single wire of size 1.5mm2/16AWG. For two wires per terminal, use smaller gauge

wire such as 0.5mm2/22AWG.

♦ Use screened control cables to comply with EMC requirements. All screens must be terminated using the cable clamp on

the Control Module. (Where the drive is a bottom wire entry version, screens must be terminated close to the terminal
blocks in the bottom of the drive using DIN rail mounted screen clamps).

♦ The control board 0V at X14/04 must be connected to protective (clean) earth outside of the product to meet EMC and

safety requirements. Provide a separate clean earth connection to this terminal from outside of the drive.

C h a p t e r 3 : I n s t a l l i n g t h e D r i v e 3-17

WARNING

Motor Thermistor

♦ If the motor does not have a protective device (thermistor), it is important to link these terminals (supplied linked by

default), or set SETUP::TRIPS::I/O TRIPS::INVERT THERMIST to True. The drive needs the thermistor inputs
connected for it to run.

♦ Connect a motor thermistor PTC `Type A’, or motor thermal switch. The drive will trip when

the thermistor resistance exceeds 4kΩ maximum (IEC 34-11 Part 2), or thermal switch opens.

♦ Connect the motor's thermistor in any order. Run the wiring in front of the Control Module,

securing it to other control wiring. Secure the wiring to the left hand side of the drive, tucking
it away behind trunking where possible.

♦ The drive uses the following resistance thresholds:

Ω

Rising temperature trip resistance: 1650 to 4000
Falling temperature trip reset resistance: 750 to 1650Ω

NOTE These connections are not necessary for normal operation of the drive.

Supply an external 0V and +24V DC (±10%) control supply to this terminal to
configure and commission the drive without the 3-phase supply present. The drive
will not turn a motor. Each AC890PX can draw 2A, so for example: 3 units = 6A.

You can connect up to four AC890PX units using these terminals by daisy-chaining
the 24V supply (8A maximum). If you have more than four AC890PXs, wire each
drive individually from the 24V source.

Connection is not required when the 3-phase supply is present, but the connection
can be safely left connected.

The units are protected against reversal of this 24V DC supply.

1. Apply the 24V DC.

Simplest method involving no speed feedback and no compensation for load changes.

Autotune is not required.

SENSORLESS
VEC

CLOSED-LOOP
VEC

Set-up using the Sensorless Vector Fluxing Mode - medium performance applications

where the drive uses an electrical model of the motor to automatically compensate for load
changes.

The drive must be tuned to the motor in use by matching the motor parameters in the drive
to those of the motor being controlled.

You MUST use the Autotune feature after entering your parameter values.

Set-up using the Closed-Loop Vector Mode - high performance applications where the
drive uses external sensors (encoders) to automatically compensate for load changes.

In this mode, speed feedback signals from the motor shaft encoder are processed to
determine the rotational speed of the shaft. A PI algorithm within the software uses this
information to produce varying gate drive signals to the drive circuits. These signals cause
the drive to output the required voltage and frequency for a particular motor speed.

You MUST use the Autotune feature after entering your parameter values.

In this mode, speed feedback signals from the motor shaft encoder are processed to
determine the rotational speed of the shaft. A PI algorithm within the software uses this
information to produce varying gate drive signals to the drive circuits. These signals cause
the drive to output the required voltage and frequency for a particular motor speed.

Autotune is not required.

The Motor Selection Wizard in the 890 DSE Configuration Tool MUST be used to
correctly set-up the motor and feedback device parameters. Failure to do so may result in
damage to the servo motor.

Step 4: Run the Motor

WARNING

Remove the fuses (or trip the circuit breaker) on your 3-phase supply.

Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.

Allow at least 10 minutes for the drive's capacitors to discharge to safe voltage levels (<50V).

4.1: The Autotune Feature

NOTE You MUST carry out an Autotune, unless the drive is in Volts/Hz Mode (Open-Loop Drive) or in PMAC control mode

(Autotune will not perform in these modes as it is unnecessary - go to page 3-42).

The Autotune feature identifies motor characteristics to allow the drive to control the motor.
It loads the values into the parameters below, which are in the QUICK SETUP menu.

NAMEPLATE RPM (motor nameplate speed)
MOTOR POLES (the number of motor poles)
ENCODER LINES (if an encoder is fitted, enter the number of lines used by the encoder)

AC890PX AC Drive

C h a p t e r 3 : I n s t a l l i n g t h e D r i v e 3-39

Performing a Rotating Autotune

NOTE The drive will not perform an Autotune when in Volts/Hz Mode (Open-Loop Drive.) An Autotune is not necessary in

this control mode.

Check that the motor can rotate freely in the forward direction. Ensure also that the motor is unloaded. Ideally, the motor
shaft should be disconnected. If the motor is connected to a gearbox this is okay, provided that there is nothing on the output
of the gearbox which could load the motor.

1. In the QUICK SETUP menu, set MAX SPEED to the maximum speed at which you will operate the drive in normal

operation. The Autotune will characterise the motor up to 30% above this speed. If you later wish to run faster than this,
you will need to carry out another Autotune.

2. Set AUTOTUNE ENABLE to TRUE, and start the drive . The drive will carry out a Rotating Autotune (indicated by

the Run and Stop led’s flashing. This may take several minutes, during which the motor will be accelerated to maximum
speed and then brought to a stop. When complete, the drive is returned to the stopped condition and the AUTOTUNE
ENABLE parameter is reset to FALSE. In Closed-loop Vector mode (with an encoder) the encoder sign has been adjusted
by the Autotune feature.

Performing a Stationary Autotune

NOTE The drive will not perform an Autotune when in Volts/Hz Mode (Open-Loop Drive.) An Autotune is not necessary in

this control mode.

Before starting the stationary Autotune, you MUST enter the value of magnetising current for the motor. This may be
available on the motor nameplate. If not, you may need to contact the motor supplier.

1. In the QUICK SETUP menu, set the AUTOTUNE MODE parameter to STATIONARY (0).

2. Set ENABLE to TRUE, and start the drive . The drive will carry out a stationary Autotune, injecting current into the

motor but not turning the shaft. The Run and Stop led’s will flash. When complete, the drive is returned to the stopped
condition and the AUTOTUNE ENABLE parameter is reset to FALSE.

IMPORTANT

Now perform a SAVE CONFIG to save your new settings. Refer to Chapter 6: “The Keypad” - Quick Save Feature.

• If the drive is configured to run in Sensorless Vector mode, set-up is complete.

• If the drive is configured to run in Closed-loop Vector mode, i.e. using an encoder, then the encoder direction must be set

up. Refer to “Setting the Encoder Sign” below.

AC890PX AC Drive

C h a p t e r 3 : I n s t a l l i n g t h e D r i v e 3-41

Setting the Encoder Sign (Closed-Loop Vector Mode)

If you have performed a Stationary Autotune in Closed-loop Vector mode, you should check the encoder direction as follows:

Look and listen to the motion of the motor when the drive is running at a speed demand of between 5 - 10%.

As a test, use the Rotary Controller (S) key on the MMI to increase the speed to about double the original figure. Change the
direction of rotation using the FWD/REV control key.

If ENCODER INVERT is correct, the motor will rotate smoothly and will respond to the changes in speed demand and
direction.

If ENCODER INVERT is incorrect, the motor will rotate in a jerky and/or noisy manner. Alternatively, it may rotate
smoothly at a very low speed but not respond to changes in speed demand or direction.

• Change the setting of ENCODER INVERT to change the encoder sign.

• Change the direction of rotation back to the original direction. Re-set the speed demand.

The encoder sign is now correct for the original motor direction.

If however the direction of the motor is incorrect at this point, then power down the entire drive, wait for 3 minutes (for the dc
link capacitors to discharge) and then swap the motor drive cables M1/U and M2/V. Change the setting of ENCODER
INVERT.

IMPORTANT

AC890PX AC Drive

The encoder sign is now correct for the new motor direction.

Now perform a SAVE CONFIG to save your new settings. Refer to Chapter 6: “The Keypad” - Quick Save Feature.

4.2: Initial Start-Up Routines

Unpredictable motion, especially if motor parameters are incorrect.

Ensure no personnel are in the vicinity of the motor or any connected machinery.

Ensure that no machinery connected to the motor will be damaged by unpredictable motion.

Ensure that the emergency stop circuits function correctly before running the motor for the first time.

The Routines 1 & 2 below will run the drive in the default V/F fluxing control mode (VOLTS / HZ) to begin with using
either the Keypad or the Control Terminals.

Now perform a SAVE CONFIG to save your new settings. Refer to Chapter 6: “The Keypad” - Quick Save Feature

Routine 1: Local Mode

NOTE Refer to Chapter 6: “The Keypad” to familiarise yourself with the keypad and menu structure.

Local control has a use for commissioning a drive. It is not the expected way to operate a system drive.

External Braking Resistors

Main Points

♦ We recommend using a thermal overload switch to protect the braking circuit. Refer to page 4-5.

♦ Use the DSE 890 Configuration Tool to configure the following parameters in the AC890PX drive:

Set the INT DB RESISTOR parameter (PREF 31.75 in the DYNAMIC BRAKING function block) to FALSE. Also
enter information about the external resistor being used in to this function block. Enable the "Brake Resistor" and
"Brake Switch" trips in the TRIPS STATUS function block (DISABLE TRIPS parameter).

IMPORTANT

Calculation

The continuous rating quoted is not to be exceeded under repetitive loading.

Brake resistor assemblies must be rated to absorb both peak braking power during deceleration and the average power over
the complete cycle.

Dynamic Brake Resistor Overload Protection

We recommend that the braking resistor and wire are protected by a motor circuit protector rated at 110% of the continuous
current rating of the resistor(s).

Route the braking wire through all three poles of the Dynamic Brake Resistor Overload Protection (part number
DC471346U032). An auxiliary contact can be used to annunciate an alarm if a trip should occur.

NOTE Intermediate overload circuit breakers are available if required:

Circuit Breakers

Circuit breakers (e.g. RCD, ELCB, GFCI), must:

• Operate correctly with dc and ac protective earth currents (i.e. type B RCDs as in Amendment 2 of IEC755).

• Have adjustable trip amplitude and time characteristics to prevent nuisance tripping on switch-on.

High frequency and dc components of earth leakage currents will flow under normal operating conditions. Under certain fault
conditions larger dc protective earth currents may flow. The protective function of some circuit breakers cannot be guaranteed
under such operating conditions.

WARNING

Circuit breakers used with VSDs and other similar equipment are not suitable for personnel protection. Use

another means to provide personal safety. Refer to EN60204-1

Control Philosophy

There are four ways to control the drive using Remote and Local control:

Figure 3.1

Remote and Local Control Modes

AC890PX AC Drive

C h a p t e r 5 : O p e r a t i n g t h e D r i v e 5-3

Start/Stop and Speed Control

There are two forms of control in operation at any time: Start/Stop and Speed Control. Each can be individually selected to be
under either Local or Remote Control.

• Local or Remote Start/Stop decides how you will start and stop the drive.

• Local or Remote Speed Control determines how you will control the motor speed.

In each case, Local and Remote control are offered by using the following:

Local: The Keypad
Remote: Analog and digital inputs and outputs, RS232 Port or Technology Options

NOTE Refer to Appendix D: "Programming" - LOCAL CONTROL.

AC890PX AC Drive

5-4 C h a p t e r 5 : O p e r a t i n g t h e D r i v e

Thus the drive can operate in one of four combinations of local and remote modes:

Figure 3.2 The Four Combinations of Local and Remote Control

NOTE Start/Stop is also known as “Sequencing”.

Speed Control is also known as “Reference Generation”.

AC890PX AC Drive

C h a p t e r 5 : O p e r a t i n g t h e D r i v e 5-5

The Start/Stop Mode Explained

The default configuration below shows the drive in Remote control, (using the analog and digital inputs and outputs). This
example will be referred to in the following explanations.

Start/Stop Controlled Remotely

In the configuration shown, the reference value is obtained by summing ANALOG INPUT 1 and ANALOG INPUT 2. The
direction of rotation is controlled by DIGITAL INPUT 4. When the RUN input (DIGITAL INPUT 1) is TRUE, the SPEED
DEMAND ramps up to the reference value at a rate controlled by ACCEL TIME. The drive will continue to run at the
reference value while the RUN input remains TRUE.

Similarly when the JOG input (DIGITAL INPUT 5) is TRUE, the SPEED DEMAND ramps up to the JOG SETPOINT at a
ramp rate set by JOG ACCEL TIME (not shown in the diagram).
The drive will continue to run at the JOG SETPOINT while the JOG input remains TRUE.

Start/Stop Controlled Locally

The reference value is set by the SETPOINT (LOCAL) parameter. (The direction of rotation is controlled by the DIR key
(forward/reverse) on the 6901 Keypad). When the RUN key is pressed, the SPEED DEMAND ramps up to the reference
value at a rate controlled by ACCEL TIME. The drive will continue to run at the reference value even when the RUN key is
released. Press the STOP key to “stop” the drive.

When the JOG key is pressed and held, the SPEED DEMAND ramps up to the JOG SETPOINT at a ramp rate set by JOG
ACCEL TIME (not shown in the diagram). Release the JOG key to “stop” the drive.

Interaction between RUN and JOG

Only one of these signals can be in effect at any one time; the other signal is ignored. The drive must be “stopped” to change
from running to jogging, or vice versa.

Start/Stop Mode Diagnostics

In the configuration shown, Start/Stop mode provides two DIGITAL OUTPUT signals (RUNNING and HEALTH).

The RUNNING signal is TRUE from the time a start command is processed until a stop sequence is completed. This
normally means the time between the drive starting until the power stack is quenched. Refer to Appendix B : “Sequencing
Logic” for a more detailed description.

AC890PX AC Drive

The HEALTH output is TRUE when the drive is not tripped.

Additional diagnostic parameters are available when using the Keypad. Refer to Chapter 7: "Keypad Menus".

Starting and Stopping Methods

NOTE Refer to Appendix D: “Programming” - REFERENCE, SEQUENCING LOGIC, REFERENCE STOP and

REFERENCE RAMP, for explanations of parameters.

Normal Stopping Methods

The Shipping Configuration is set to “Ramp to Stop” (at STOP TIME, set to 10.0s).

• To “stop” the locally controlled drive press the STOP key on the Keypad

• To “stop” the remotely controlled drive remove the 24V from the RUN input (terminal X15/02), and from the STOP input

(terminal X15/03)

Using the Keypad or DSE Configuration Tool, the drive can be selected to “Ramp to Stop”, or to “Coast to Stop” at one of
two rates (STOP TIME or FAST STOP TIME). To do this, change the RUN STOP MODE parameter (PREF102.01) to the
required selection.

Ramp to Stop

Set the SETUP::SEQ & REF::REFERENCE STOP::RUN STOP MODE parameter to RUN RAMP.

When a stop command is received, the drive decelerates from its actual speed towards zero for the programmed DECEL
TIME time. When this time has elapsed, SPEED TRIM is ramped to 0% in the programmed STOP TIME time.

NOTE If SPEED TRIM does not operate, SPEED DEMAND is reduced to 0% in DECEL TIME.

The power stack remains energised until the STOP DELAY period has elapsed.

Advanced Stopping Methods

The drive can be selected to NOT FAST STOP or to NOT COAST STOP. The stopping procedure is unaffected by Local or
Remote Sequencing options.

Forced Fast Stop

The Not Fast Stop mode overrides the RUN FORWARD, RUN REVERSE and JOG inputs in Remote mode, and the RUN
and JOG Keypad keys in Local mode.

Select the SETUP::SEQ & REF::REFERENCE STOP::FAST STOP MODE parameter to either RAMP or COAST. The
stopping sequence starts when the NOT FAST STOP input goes FALSE, regardless of the state of the RUN input.

The Trip Condition

When a trip condition is detected, a similar stopping method to NOT COAST STOP is used. The power stack cannot be re­enabled until the trip condition has been cleared and successfully reset.
Refer to Chapter 8: “Trips and Fault Finding” for further details.

Logic Stopping

The drive can be stopped by setting the NOT STOP to FALSE for a short time, (>100 ms). The stop sequence continues even

IMPORTANT

DRIVE ENABLE must be True in all cases.

Single Wire Logic Starting

Use just DIGITAL INPUT 2 when the motor direction will always be the same. The motor will run while the RUN switch is
closed, and will stop when it is open.

Note that the SETUP::SEQ & REF::SEQUENCING LOGIC::NOT STOP parameter is active (FALSE - not wired to),
meaning that the drive will only run while the RUN parameter is held TRUE.

Two Wire Logic Starting

Re-configure the DSE 890 default configuration(s) by connecting SETUP::SEQ & REF::SEQUENCING LOGIC::REMOTE
REV OUT to SETUP::SEQ & REF::REFERENCE::REMOTE REVERSE.

This uses two inputs; RUN and REVERSE. The drive can operate in forward and reverse depending upon which switch is
closed. If both RUN and REVERSE are TRUE (24V) at the same time, both are ignored and the drive will stop.

Note that the SETUP::SEQ & REF::SEQUENCING LOGIC::NOT STOP parameter is active (FALSE - not wired to),
meaning that the drive will only run while the RUN parameter is held TRUE.

• Fit normally-open push button switches to RUN FORWARD and RUN REVERSE.

• Fit a normally-closed push button switch to NOT STOP, thus NOT STOP is held TRUE (24V). When TRUE, the action of

NOT STOP is to latch the RUN FORWARD and RUN REVERSE signals. When FALSE, these signals are not latched.

For example, operating the RUN FORWARD switch starts the drive running forward. Operating the RUN REVERSE switch
causes the drive to run in reverse. Operating the NOT STOP switch (making “NOT STOP” FALSE) at any time causes the
drive to stop running.

NOTE The JOG parameter is never latched in this way. The drive only jogs while the JOG parameter is TRUE.

Starting Several Drives Simultaneously

IMPORTANT

AC890PX AC Drive

We do not recommend that the DRIVE ENABLE signal is used to start a drive in “normal” use.

Use the DRIVE ENABLE parameter to control the output power stack. When this parameter is FALSE, the power stack is
disabled regardless of the state of any other parameters. In conjunction with the HEALTH output parameter, DRIVE
ENABLE can synchronise several drives on power-up.

Application Advice

• Application advice is available through our Technical Support Department, who can also arrange for on-site assistance

if required. Refer to the back cover of this manual for the address of your local Parker SSD Drives company.

• Always use gold flash relays, or others designed for low current operation (5mA), on all control wiring.

• Remove all power factor correction equipment from the motor side of the drive before use.

• Avoid using motors with low efficiency and small cos ø (power factor) as they require a larger kVA rated drive to

produce the correct shaft kW.

Brake Motors

Brake motors are used in applications requiring a mechanical brake for safety or other operational reasons. The motor can be
a standard induction motor fitted with an electro-mechanical brake, or it could be a special conical rotor machine. In the case
of a conical rotor machine the spring-loaded brake is controlled by the motor terminal voltage as follows:

At rest the motor is braked.

When the motor is energised an axial component of the magnetic field due to the conical air-gap overcomes the force of the
brake spring and draws the rotor into the stator. This axial displacement releases the brake and allows the motor to accelerate
like a normal induction motor.

When the motor is de-energised the magnetic field collapses and the brake spring displaces the rotor, pushing the brake disc
against the braking surface.

Drives can be used to control the speed of conical rotor brake motors since the linear V/F characteristic maintains the motor
magnetic field constant over the speed range. It will be necessary to set the FIXED BOOST parameter to overcome motor
losses at low speed (see the FLUXING menu on the Keypad).

Using Output Contactors

The use of output contactors is permitted. It is recommended that this type of operation be limited to emergency use only or in
a system where the drive can be inhibited before closing or opening this contactor.

Using Motor Chokes (output)

Motor chokes may be used with the 380V/460V and 500V/575V AC890PX AC Drive.

Installations with long cable runs may suffer from nuisance overcurrent trips. A choke may be fitted in the drive output to
limit capacitive current. Screened cable has a higher capacitance and may cause problems in shorter runs. A choke may be
used on cable lengths of over 100m.

Using Multiple Motors on a Single Drive

A single large drive can be used to supply several smaller motors provided that
each individual motor has overload protection.

NOTE Conventional V/F control strategy must be enabled for use with parallel

motors. (Sensorless vector control strategy cannot be used). See the
VECTOR ENABLE parameter under VECTOR SET-UP menu at level 2.

VSD

The drive must be rated to supply the total motor current. It is not sufficient
to simply sum the power ratings of the motors, since the drive has also to
supply the magnetising current for each motor.

Note that the overload device will not prevent the motor overheating due to
inadequate cooling at low speed. Force vented motors may be required; consult
your motor supplier.

All motors should be connected to the drive output before the START command is given.

Caution

Restrict the total cable length on multiple motor installations as follows:

High Starting Torque

Applications requiring high motor starting torque (greater than 100% of rated torque) need careful setup of the drive voltage
boost feature. Gradually increase the FIXED BOOST parameter in 1% steps until the drive generates sufficient starting
torque.

It is important to use the minimum level of FIXED BOOST necessary to accelerate the load. Using a level of FIXED BOOST
higher than necessary will lead to increased motor heating and increased risk of drive overload.

Setting the FIXED BOOST parameter level too high can also cause the drive current limit feature to operate. If this occurs,
the drive will be unable to ramp up in frequency. The IT LIMITING diagnostic (INVERSE TIME function block) will
indicate TRUE when the inverse time current limit feature is operating. Simply reducing the level of the FIXED BOOST
parameter will remove this problem.

NOTE Motor torques greater than 100% require high currents to be drawn from the drive. Thus, the CURRENT LIMIT

parameter (CURRENT LIMIT function block) will have to be set accordingly such that the drive current limit feature
will not activate when accelerating the load.

The best motor starting performance can be achieved by setting up the SLIP COMP function block, refer to the Appendix D:
“Programming” - SLIP COMP. Also setting the BASE VOLTS parameter (VOLTAGE CONTROL function block) to

115.4% and the FREQ SELECT parameter (PATTERN GEN function block) to 3kHz, can help to start difficult loads in the
most extreme cases.
