Overload protection at low frequency (oL3)

Low frequency and high current protection

The drive operates at a frequency below 15 Hz, and output current is too large -

1. Enhance the heat dissipation capacity for the cabinet.
2. Lower the carrier frequency (Pr.00-17).

3. Decrease the voltage settings that correspond to frequency below 15 Hz in
the V/F curve.

4. Change Pr.00-11 to general control mode.

5. Replace the drive with a larger power model.
