Description
Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See
section Continuous magnetization (page
The magnetization current is calculated on the basis
of flux reference (see parameter group
control).
Note:
• 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.
0 = Normal operation

Note: This parameter cannot be changed while the
drive is running.
This mode gives the most accurate autophasing result.
This mode can be used, and is recommended, if the
motor is allowed to rotate and the start-up is not
time-critical.
Note: This mode will cause the motor to rotate. The
load torque must be less than 5%.
Faster than the Turning
motor will not rotate.
An alternative standstill autophasing mode that can
be used if the Turning
Standstill 1 mode gives erratic results. However, this
mode is considerably slower than
This mode should be used if the zero pulse signal of
the pulse encoder is to be observed, and other modes
do not give a result. The motor will turn until a zero
pulse is detected.
