Rated operating
torque
Example
5-12
If the rated operating torque of the motor is not indicated on the name plate, it
can be calculated using the following formula:
If no value is specified, the value of the basic factory setting is active (0 Nm).
When the start command is given and the motor is connected, the required value
is automatically calculated once by the soft starter.
Notice
If a motor with rated data (current, speed, torque) that differ from the values already
entered is connected to the soft starter (e.g. for testing purposes), these rated data must
be adapted to the new motor. If 0 Nm is entered as the rated operating torque, the value is
automatically calculated once by the soft starter.
