Continuous magnetization
A digital signal, such as a user bit in the fieldbus control word, can be selected to
activate continuous magnetization. This can be especially useful in processes
requiring motors to be stopped (for example, to stand by until new material is
processed), then quickly started without magnetizing them first.
Note:
Continuous magnetization is only available in speed control in DTC motor
control mode (see page
), and only when ramping is the selected stop mode (see
WARNING:
The motor must be designed to absorb or dissipate the thermal
energy generated by continuous magnetization, for example by forced
ventilation.

The motor potentiometer is, in effect, a counter whose value can be adjusted up and
down using two digital signals selected by parameters
