PARAMETER DESCRIPTIONS
1401 STOP STATE FLUX 6 (2.6.23.24)
The amount of flux as a percentage of the motor nominal flux maintained in the motor after
the drive is stopped. The flux is maintained for the time set by parameter ID1402. This
parameter can be used in closed loop motor control mode only.
1402 FLUX OFF DELAY 6 (2.6.23.23)
The flux defined by parameter ID1401 is maintained in the motor for the set time after the
drive is stopped. This function is used to shorten the time before the full motor torque is
available.

ped.
>0 The flux off delay in seconds.
The flux is maintained in the
motor after stop until the next
<0
Run request is given to the
drive.
1412 TORQUE STABILIZER GAIN 6 (2.6.26.1)
Additional gain for the torque stabilizer at zero frequency.
1413 TORQUE STABILATOR DAMPING 6 (2.6.26.2)
This parameter defines the time constant for the torque stabilator. The greater the
parameter value, the shorter the time constant.
If a PMS motor is used in Open Loop control mode it is recommended to use value 980 in this
parameter instead of 1000.
1414 TORQUE STABILATOR GAIN IN FIELDWEAKENING POINT 6 (2.6.26.3)
The general gain for the torque stabilator.
1420 PREVENTION OF STARTUP 6 (2.2.7.25)
This parameter is enabled when the "Prevention of start" circuit is used to inhibit the gate
pulses. The parameter is available for NXP drives only.
1424 RESTART DELAY 6 (2.6.17)
The delay time within which the drive can not be restarted after a coast stop. The time can be
set up to 60.000 seconds. The Closed Loop control mode uses a different delay.
