The bus voltage is
abnormal.
The rectifier bridge, the
buffer resistor, the drive
board or the control board
are abnormal.

The AC drive power class
is small.


Increase deceleration time.

Install braking unit and braking
resistor.

Ensure that the voltage limit function
is enabled (P3-23 )

The setting of voltage limit (F3-22)
is too large. Adjust it between 700 V
and 770 V.

The setting of frequency gain for
voltage limit (P3-24) is too small.
Adjust it between 30 and 50.

The setting of frequency rise
threshold during voltage limit (P3-
26) is too small. Adjust it between 5
Hz and 20 Hz.

Cancel the external force or install a
braking resistor

Arrange voltage in a reasonable range

Enable the power dip ride through
function (P9-59 ).

Adjust the voltage to normal range.



Reduce load or check motor and
mechanical conditions.

Replace a drive of larger power
class.

Set P9-01 correctly.

Reduce load or check motor and
mechanical conditions.
