OV or OC is Detected when the Fan is Started or Stalls

Generation of OV (control circuit overvoltage) or OC (overcurrent) and stalling can occur if the fan is turning
when it is started. The DC injection braking is insufficient when starting.

This can be prevented by slowing fan rotation by DC injection braking before starting the fan. Increase the
parameter b2-03 (DC Injection Braking Time /DC Excitation Time at Start) setting.

Or, validate the settings of b3-01 (Speed Search Selection).

Output Frequency does not Reach the Specified Frequency Reference

Use the following information if the output frequency does not reach to the frequency reference.

The frequency reference is within the jump frequency range.

When the jump frequency function is used, the output frequency does not change within the jump frequency
range. Check to be sure that the Jump Frequency (d3-01 to d3-03) and Jump Frequency Width (d3-04) settings
are suitable.

The frequency reference upper limit has been reached.

The output frequency upper limit is determined by the following formula:
Maximum Output Frequency (E1-04)

×

Frequency Reference Upper Limit (d2-01) / 100

Check to be sure that the parameter E1-04 and d2-01 settings are suitable.
