Parameters 147
Activates/deactivates the DC hold and post-magnetization
functions. See section
(page
).
Notes:
• These functions are only available in speed control in
Vector 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.

Defines the DC hold current in percent of the motor nominal
current. See parameter

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 when ramping is the selected
stop mode (see parameter
), and only in
speed control in Vector motor control mode (see page
• 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.
