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
parameter
, and section
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
,
and section
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 source for triggering pre-heating for the motor.
The status of the pre-heating is shown as bit 2 of
.
Notes:
• The heating function requires that STO is not triggered.
• The heating function requires that the drive is not
faulted.
• Pre-heating uses DC hold to produce current.
Off
0. Pre-heating is always deactivated.
0
On
1. Pre-heating is always activated when the drive is
stopped.

DC hold
1 = DC hold. See section
Note:
The DC hold function has no effect if the start signal is switched
off.

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.
