Operation on the frequency inverter
Note!
A label in the terminal box shows the limit values of the
voltages for your motor.
ƒ During operation of the motors on the frequency inverter or during switching
operation on the mains
voltage peaks can occur, which can damage the motor insulation.
ƒ In order to avoid malfunctions, the limit values specified
in the table must not be exceeded:
Application of the motor on the
Frequency inverter,
single-phase
Frequency inverter, three-phase
Mains (switching operation)
Tip!
For switching operation on the mains you can limit the voltage peaks by
ƒ
means of a suppressor circuit with RC elements or varistors (not included
in the scope of supply).
Dimension the suppressor circuit for the respective application case!
