7.9 Motor heating
Motor heating can be used as a pre-start function to
heat the motor before actual start without any rotation to
the motor. It can also be used as an individual function
operated from a digital input or fieldbus.
The softstarter supplies a current to the engine, without
reaching the torque level that starts the engine. This
warms up the engine without starting it.
Motor heating is configured with the following
parameters:
