The over current stall
prevention
parameters are set
improperly.
The AC drive power class
is small.
The drive suffers external
interference.
Input voltage is too high.
An external force drives
motor during
acceleration.
The over voltage stall
prevention
parameters are set
improperly.
Braking unit and braking
resistor are
not installed.
Acceleration time is too
short.
The over voltage stall
prevention
parameters are set
improperly.
An external force drives
motor during
deceleration.

Ensure that current limit is enabled
(P3-19).

The setting of current limit level (P3-
18) is too large. Adjust it
between 120% and 150%.

The setting of current limit gain (P3-
20) is too small. Adjust it
between 20 and 40.

If output current exceeds rated motor
current or rated output current of the
AC drive during stable running,
replace a drive of larger power class.

View historical fault records. If the
current value is far from the over
current level, find interference
source. If external interference does
not exist, it is the drive board or hall
device problem.

Adjust input voltage to normal
range.

Cancel the external force or install a
braking resistor.

Ensure that the voltage limit function
is enabled (P3-23 ).

The setting of voltage limit (P3-22)
is too large. Adjust it between700 V
and 770 V.

The setting of frequency gain for
voltage limit (P3-24) is too small.
Adjust it between 30 and 50.

Install braking unit and braking
resistor.

Increase acceleration time.

Ensure that the voltage limit function
is enabled (P3-23 ).

The setting of voltage limit (P3-22)
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.

Cancel the external force or install
braking resistor.
