WARNING:
The motor needs to be rated to absorb the thermal energy
generated by flux braking.

DC magnetization
The drive has different magnetization functions for different phases of motor
start/rotation/stop: pre-magnetization, DC hold, post-magnetization and pre-heating
(motor heating).
Pre-magnetization
Pre-magnetization refers to DC magnetization of the motor before start. Depending
on the selected start mode (
), pre-
magnetization can be applied to guarantee the highest possible breakaway torque,
up to 200% of the nominal torque of the motor. By adjusting the pre-magnetization
time (
), it is possible to synchronize the motor start and, for
example, the release of a mechanical brake.

DC hold
The function makes it possible to lock the rotor at (near) zero speed in the middle of
normal operation. DC hold is activated by parameter
. When
both the reference and motor speed drop below a certain level (parameter
), the drive will stop generating sinusoidal current and start to inject DC
into the motor. The current is set by parameter
. When the
