• For adjustment, observe the thermal performance of the connected
asynchronous motor at low output frequencies.
– Usually, standard asynchronous motors with insulation class B can be
operated for a short time with their rated current in the frequency range 0
Hz ... 25 Hz.
– Contact the motor manufacturer to get the exact setting values for the
max. permissible motor current of self-ventilated motors in the lower
speed range.
• The nameplate data of the motor (at least rated speed and rated frequency)
must be entered if, instead of a standard motor, an asynchronous motor is
used with the following values:
– rated frequency
≠
50 Hz (star) or
– rated frequency
≠
87 Hz (delta) or
– number of pole pairs
