Parameters 209
Activates/deactivates the DC hold and post-magnetization
functions. See section
(page
).
Notes:
• DC hold is only available with speed control in DTC motor
control mode (see page
).
• 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 magnetization selection.
1 = 1
Defines the DC hold speed. See parameter

DC hold speed.
See par.
Defines the DC hold current in percent of the motor nominal
current. See parameter
, and section
).
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
Continuous
magnetization
command
Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See section
(page
The magnetization current is calculated on the basis of flux
reference (see parameter group
Notes:
• This function is only available in DTC motor control mode.
• Continuous magnetization causes the motor to heat up. In
applications where long magnetization times are required,
externally ventilated motors should be used.
• Continuous magnetization may not be able to prevent the
motor shaft from rotating during a long period if a constant
load is applied to the motor.

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

Note:
Post-magnetization is only available when ramping is the selected stop mode (see
