Description
Activates/deactivates the DC hold and post-magnetization
functions. See section
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.
DC hold

DC magnetization selection.
Defines the DC hold speed in speed control mode. See
parameter 21.08 DC current
(page 70).
DC hold speed.
Defines the DC hold current in percent of the motor nominal
current. See parameter
DC magnetization (page 70).
After 100 s post-magnetization time, the maximum
magnetization current is limited to the magnetization current
corresponding to the actual flux reference.
DC hold current.
Defines the length of time for which post-magnetization is
active after stopping the motor. The magnetization current is
defined by parameter
See parameter 21.08 DC current
Post-magnetization time.
Selects the source for controlling pre-heating for the motor.
The status of the pre-heating is shown as bit 2 of
status word 3.
Notes:
• The heating function requires that STO is not triggered.
• The heating function requires that the drive is not faulted.
0. Pre-heating is always deactivated.
1. Pre-heating is always activated when the drive is stopped.
