140 Parameters
Activates/deactivates the DC hold and post-
magnetization functions. See section
on page
.
Note:
DC magnetization causes the motor to heat up.
In applications where long DC magnetization times
are required, externally ventilated motors should be
used. If the DC magnetization period is long, DC
magnetization cannot prevent the motor shaft from
rotating if a constant load is applied to the motor.
0b0000
0b0000…0b1111
DC magnetization selection.
1 = 1
Defines the DC hold speed in speed control mode. See
.
5.00 rpm
0.00…1000.00 rpm
DC hold speed.
See par.
Defines the DC hold current in percent of the motor
nominal current. See parameter
on page
.
After 100 s post-magnetization time, the maximum
magnetization current is limited to the magnetization
current corresponding to the actual flux reference.
30.0%
0.0…100.0%
DC hold current.
1 = 1%
Defines the length of time for which post-
magnetization is active after stopping the motor. The
magnetization current is defined by parameter
.
See parameter
0 s
0…3000 s
Post-magnetization time.
1 = 1 s
Selects the way autophasing is performed during the
ID run. See section
on page
Turning
This mode gives the most accurate autophasing
result. This mode can be used, and is recommended,
if the motor is allowed to rotate during the ID run and
the start-up is not time-critical.
0
No.

DC hold
1 = DC hold. See section
on page
Note:
The DC hold function has no effect if the start signal is
switched off.
1
Post-
magnetization
1 = Post-magnetization. See section
on page
Note:
Post-magnetization is only available when ramping is the
selected stop mode (see parameter
).
2
DC brake
1 = Enable DC brake.
