Bit Value
0 1 = Enable DC hold. See section
Note: The DC hold function has no effect if the start signal is switched off.
1 1 = Enable post-magnetization. See section
Note: Post-magnetization is only available when ramping is the selected stop mode (see

Description
Activates/deactivates the DC hold and post-magnetization
functions. See section
Notes:
• These functions are only available in speed control in DTC
motor control mode (see page 26).
• 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 current.
Defines the length of time for which post-magnetization is
active after stopping the motor. The magnetization current is
defined by parameter

Post-magnetization time.
Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See section
Continuous magnetization
The magnetization current is calculated on the basis of flux
reference (see parameter group
Notes:
• This function is only available when ramping is the
selected stop mode (see parameter
only in speed control in DTC motor control mode (see page
26).
• 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.
