The flux defined by parameter
ID 1401
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.
0 = No flux after the motor is stopped.
>0 = The flux off delay in seconds.
<0 = The flux is maintained in the motor after stop until the next Run request is given to the drive.
10.504 (ID 1412) Torque Stabilator Gain
Location in the menu:
P2.6.18.1
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the gain of the torque stabilator in an open loop control operation.
Extra gain for the torque stabilizer at zero frequency.
10.505 (ID 1413) Torque Stabilator Damping Time Constant
Location in the menu:
P2.6.18.2
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the damping time constant of the torque stabilizer.
The greater the parameter value, the shorter the time constant. If a PMS motor is used in Open Loop control mode, it is recommen-
ded to use value 980 in this parameter instead of 999.
10.506 (ID 1414) Torque Stabilator Gain in Fieldweakening Point
Location in the menu:
P2.6.18.3
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the gain of the torque stabilator at field weakening point in an open loop control operation.
10.507 (ID 1424) Restart Delay
Location in the menu:
P2.6.8
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the time delay during which the drive cannot be restarted after coast stop (flying start not in use).
The time can be set up to 60.000 s. The Closed Loop control mode uses a different delay.
This function is not available when flying start is selected for start function (
ID 505
).
10.508 (ID 1516) Modulator Type
Location in the menu:
P2.4.20
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to select the modulator type.
Some operations require use of a software modulator.

name
Description
0
ASIC modula-
tor
A classical third harmonic injection. The spectrum is slightly better compared to the Software 1
modulator.
An ASIC modulator cannot be used when using Drive- Synch or PMS motor with an incremental
type encoder.
1
Software Mod-
ulator 1
Symmetric vector modulator with symmetrical zero vectors. Current distortion is less than with
software modulator 2 when boosting is used.
This selection is recommended for DriveSynch (Set by default when DS activated) and needed
when using PMS motor with an incremental encoder.
10.509 (ID 1536) Follower Fault
Location in the menu:
P2.11.8
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to select the response of the Master drive to a fault in any of the follower drives.
For diagnostic purposes, when one of the drives trips to fault the master drive sends a command to trigger Data Logger in all the
drives.
10.510 (ID 1550) Flux Circle Stabilator Gain
Location in the menu:
P2.6.18.5
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the gain for the flux circle stabilizer.
