Commissioning
Rated torque
Example
5-12
If the rated 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 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 is connected to the soft starter (e.g. for testing purposes) whose rated data
(current, speed, torque) differs from the values already entered, these rated data must be
adapted to the new motor. If 0 Nm is entered as the rated torque, the value is
automatically calculated once by the soft starter.
