OV1
[7] Over-voltage
during acceleration
Deceleration time is too
short.
Exception occurred to input
voltage.
Large energy feedback.
Lack of braking units.
Dynamic brake is not
enabled
Check input power.
Check whether load
deceleration time is too short;
or the motor starts during
rotating.
Install dynamic braking units.
Check the setup of related
function codes
OV2
[8] Over-voltage
during deceleration
OV3
[9] Over-voltage
during constant
speed running
OC1
[4] Over-current
during acceleration
Acceleration is too fast.
Grid voltage is too low.
inverter power is too small.
Load transient or exception
occurred.
To-ground short circuit or
output phase loss occur.
Strong external interference
sources.
Overcurrent stall protection
is not enabled
Increase acceleration
/deceleration time;
Check input power;
Select the inverter with larger
power.
Check if the load is short
circuited (to-ground short circuit
or line-to-line short circuit) or
the rotation is not smooth.
Check the output wiring.
Check if there is strong
interference.
Check the setup of related
function codes.

undervoltage fault
Grid voltage is too low.
Overvoltage stall protection
is not enabled
Check grid input power.
Check the setup of related
function codes
OL1
[11] Motor overload
Grid voltage is too low.
Rated motor current is set
improperly.
Motor stall or load jumps
violently
Check grid voltage.
Reset rated motor current.
Check the load and adjust
torque boost
OL2
[12] inverter
overload
Acceleration is too fast.
The motor in rotating is
restarted.
Grid voltage is too low.
Load is too large.
Power is too small;
Increase acceleration time.
Avoid restart after stop.
Check grid voltage.
Select the inverter with larger
power.
Select proper motor
SPI
[13] Phase loss on
Phase loss or violent
Check the input power.
