Functional Description

The AR feature can be configured to operate in one of three modes via the parameter

1470 AR Mode

In all modes the AR feature becomes active when the drive trips on one of the trips selected by parameter

1472 AR Trip Mask

. If the drive trips due

to a trip not selected in

1472 AR Trip Mask

the AR feature will remain in the idle state.

Setting parameter

1469 AR Enable

to FALSE will disable the AR feature regardless of its current state.

1470 AR Mode 0:

Trip Reset

In Trip Reset mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature will
attempt to reset the trip event, moving the Sequencing State from the FAULTED state, (see Appendix B: Sequencing Logic). The AR feature resets
the trip as soon as possible, it does not wait for either

1505 Initial Delay

1506 AR Repeat Delay

In this mode the AR feature will not attempt to restart the motor.

This mode may be used when an external supervisiory system is monitoring the Faulted bit in

0661 Status Word

. This bit will be cleared once all trip

sources are inactive and the trip has been successfully cleared, indicating that the drive may be started.

D-20

Parameter Reference

1470 AR Mode 1:

Auto Restart

Caution: when Auto Restart is selected the motor may run unexpectedly.

In Auto Restart mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature
starts the programmed delay. Once the delay timer expires the AR feature attempts to reset the trip and to restart the motor.

The AR feature will not restart the motor if it was not running at the time of the trip, nor will it restart the motor if the run signal has been removed at
any time since the trip, (even if it is subsequently re-applied). When a motor restart will not be attempted the AR feature will act as if it had been
configured for

Trip Reset

only. If a motor restart will be attempted the parameter

1508 AR Restart Pending

is set TRUE.

Each time a restart is attempted the value in

1509 Restarts Remaining

is decremented. Once this value reaches zero, any further trip selected for

auto restart will cause the AR feature to disable itself.

1470 AR Mode 2:

Auto Start

Caution: when Auto Start is selected the motor may run unexpectedly.

In Auto Start mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature starts
the programmed delay. Once the delay timer expires the AR feature attempts to reset the trip and to restart the motor.

The AR feature will attempt to start the motor even if it was not running at the time of the trip, as long as the Sequencing Logic parameter

0644

Control Word

is configured to run, (typically bits 0, 1, 2 and 3 all set), see Appendix B: Sequencing Logic.

In this mode the parameter

1508 AR Restart Pending

is set TRUE. Each time a restart is attempted the value in

1509 Restarts Remaining

decremented. Once this value reaches zero, any further trip selected for auto restart will cause the AR feature to disable itself.

Recovery from Self Disabled state

The

AR feature will remain in the Self Disabled state indefinitely. It may be re-activated by the trip condition being reset by some other means, (ie.

Manually by pressing the stop key on the GKP, or remotely using trip reset). Alternatively the AR feature may be re-enabled by setting

1469 AR Enable

to FALSE then back to TRUE.

Indication

When the AR feature is activated the parameter

1507 AR Active

is set TRUE.

While a restart is pending the parameter

1508 AR Restart Pending

is set TRUE. In addition the green LED illuminating the run key on the GKP will

flash.
All indicators are reset once the restart, (or trip reset), attempt has been completed or if the AR feature is disabled.

Parameter Reference

D-21

Autotune

Setup:: Motor Control::Autotune
Parameters::Motor Control::Autotune

The autotune is an automatic test sequence performed by the Drive to identify motor model parameters. The motor model is used by the Vector
control modes.

If an induction motor is used, and the control mode is set to vector control, you

MUST

perform an autotune before operating the Drive. It the control

mode is set to Open Loop (V/Hz) mode an autotune is not necessary. Whether the drive is in Vector Control mode or in Open Loop mode is
determined by the parameter 0512 Control Strategy in menu Control Mode (see page D-40). Induction motor nameplate parameters must be
entered before running the autotune procedures in order for them to correctly measure motor model parameters.

The motor must be allowed to spin freely. It is acceptable for the motor to be connected to a load during autotune, provided that the load is purely
inertia, with negligible friction, and does not require the motor to produce torque in order to turn.

Sometimes it is not possible to spin the motor freely, for example it has already been connected to a machine and it is not convenient to uncouple it.
In this case a stationary autotune must be carried out.  Select Autotune Mode = STATIONARY.  If you select stationary autotune, a parameter
Nameplate Mag Current will appear.  You must enter the motor magnetising current into this parameter before proceeding with the stationary
autotune. Stationary autotune should be avoided if possible: first, because the magnetising current may not be accurate; second, because operation
above base speed requires the rotating autotune to map the motor characteristics in the field weakening region, and if this is not done, operation
may not be possible above base speed.

If a permanent magnet motor is used and there is no datasheet available from your motor provider, You MUST perform an autotune before operating
the Drive in the Vector control mode . Before running the autotune, some PMAC Motor parameters should be set. Some are available on the motor
nameplate :

0555 PMAC Max Speed

:motor rated speed

0557 PMAC Rated Current

: motor rated current

0558 PMAC Rated Torque

: motor rated torque

1387 PMAC Base Volts

: motor voltage

0556 PMAC Max Current

: motor max current ( if not known, set it to the same value as

0557 PMAC Rated Current

)

0559 PMAC Motor Poles

: motor number of poles ( should be an even number )

0564 PMAC Motor Inertia

: motor inertia : try to set good estimated value, the speed loop will use it for setting correct control parameters

If a permanent magnet motor is used and there is datasheet available from your motor provider, You must either perform an autotune before
operating the Drive in the Vector control mode or enter the required motor parameters from the datasheet.

If a permanent magnet motor is used, setting the

0412 Stack Frequency

to 4kHz or less will help to better estimate the motor resistance (

0562

PMAC Winding Resistance

For best results is is better to carry out the autotune at the maximum speed that is likely to be required. If you run the autotune at a particular speed,
the motor characteristics will be measured up to this speed, and estimated above this speed. If you later discover that you need to run the motor
faster than this, you can do this up to twice the speed at which the autotune is carried out, but the values will not be so accurate, and the control may
not be as good in this region. It is better to run another autotune at the higher speed. If you wish to run the motor at more than twice the speed at
which the autotune was carried out, this will not be allowed. If in doubt, the autotune speed is recorded in the parameter Max Spd When Autotuned,
described below.

Selects whether the autotune is carried out on a rotating motor, or whether it just calculates from nameplate data (not the preferred
method). It may be necessary to carry out a stationary autotune if the motor is not free to rotate, for example if it is already connected
to a machine. Leakage inductance (to tune the current loop) and stator resistance may be measured when the motor is stationary, but
other parameters can only be inferred from nameplate data. Use the rotating autotune where possible.

If you select stationary autotune, you must enter the motor magnetising current into this parameter before proceeding with the
stationary autotune. If this is not known, it can be approximated from the motor rated current and the power factor, as motor current

times √(1 – PF^2).

The value of mag current entered here will be copied into the magnetising current parameter in the Induction Motor Data menu. If a
rotating autotune is run at a later date, it will be replaced with the more accurate value, and this parameter will be irrelevant.

Parameters::Motor Control::Autotune

RPM

NEVER

This parameter records the value of the "100% speed in rpm" parameter at the time the autotune was carried out.

"100% speed in rpm" determines the max speed at which the motor can be commanded to run. When the autotune is carried out, it
can only measure the motor characteristics up to this speed. Beyond this speed, the motor characteristics are filled in according to the
best possible estimate, but are not necessarily accurate.

If at a later date the "100% speed in rpm" parameter is increased, then that will allow the motor to run in the region where the motor
characteristics have been estimated, not measured. The further into this region the motor is allowed to run, the less accurate will be
the motor characteristics and hence the control.

The user is allowed to increase "100% speed in rpm" up to 2 times the value stored in “Max Spd when Autotuned”. Beyond this it is
considered that the resulting control inaccuracy may be unacceptable. In this case, an error will be generated. If the user wishes to
run the motor more than 2 times the value at which it was autotuned, then he must carry out a new autotune at the higher speed.

Functional Description

When enabled, the

Braking

feature monitors the internal dc link voltage every millisecond and sets the state of the brake switch accordingly. When

using braking, the brake resistor information must be entered it ordered for the resistor protection to operate.

The

Braking

feature operates even when the motor output is not enabled. This allows the function to continually monitor the energy dumped into the

braking resistor, and the energy dissipated across the brake switch. With this information the Drive is able to deduce the loading on the brake
resistor.

Parameter Reference

D-29

If the instantaneous braking power is greater than the Brake Rated Power parameter then this overload is accumulated. If the overload area (power
excess x time) reaches the level set in the Brake Overrating parameter then the brake switch is automatically disabled. This can then lead to an
overvoltage trip protecting the inverter.

The voltage level at which braking occurs is nominally 764V, but rises linearly to 773V as the overload area rises to the Brake Overrating limit. This
improves the brake energy sharing in a multi-brake common d.c. bus system, which can be effected by variation in the exact braking voltage level in
each inverter.

The

Braking

feature also provides a control signal that is used by the

Slew Rate

limit feature. This causes the setpoint to be temporarily frozen

whenever the brake is operating because the dc link voltage exceeds the internal comparison level. This allows the stop rate to be automatically
tuned to the characteristics of the load, motor, Drive and brake resistor.

Clone

Setup::Clone
Parameters::Device Manager::Clone

The clone feature allows the drive configuration (application and parameters) to be saved to an SD card and subsequently loaded to the same or a
different drive.

All parameters fall into one of the following cloning categories listed in the parameter table at the end of this appendix:

•

Never

: This type of parameter would never be copied to a new drive. This category includes parameters that are not saved

and parameters that contain information such as runtime statistics.

•

Drive Unique

: This type of parameter is normally unique to the drive, such as the drive name.

•

Power:

This type of parameter is related to the power stack of the drive or to the motor connected to the drive.

•

Other:

Any saved parameter that is not in the other cloning categories. This category is the majority of the parameters

including the application parameters.

The visibility of the following cloning parameters on the GKP may depend on the selection of other cloning parameters and whether an SD card is
fitted.
