Selection No.
Off / uint32 Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See
section
Continuous magnetization (page 94) .
The magnetization current is calculated on the basis
of flux reference (see parameter group
97 Motor
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.

Turning / uint16 Selects the way autophasing is performed.
See section
Autophasing (page 89) .
Note: This parameter cannot be changed while the
drive is running.
Autophasing mode 21.13
0 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%.
Turning
1 Faster than the Turning mode, but not as accurate. The
motor will not rotate.
Standstill 1
2 An alternative standstill autophasing mode that can
be used if the
Turning mode cannot be used, and the
Standstill 1 mode gives erratic results. However, this
mode is considerably slower than Standstill 1 .
Standstill 2
3 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. Turning with Z-pulse
