Post-magnetization
This function keeps the motor magnetized for a certain period (parameter
magnetization time) after stopping. This is to prevent the machinery from moving
under load, for example before a mechanical brake can be applied. Post-

Pre-heating (Motor heating)
The pre-heating function keeps the motor warm and prevents condensation inside the
motor by feeding it with DC current when the drive has been stopped. The heating
can only be on when the drive is in the stopped state, and starting the drive stops the
heating.
When pre-heating is activated and the stop command is given, pre-heating starts
immediately if the drive is running below zero speed (see bit 0 in parameter
