Possible cause

PID feedback offline;

PID feedback source
disappear.

Braking circuit fault or
damage to the brake
pipes;

The external braking
resistor is not sufficient.

The actual running time of
the VFD is larger than the
internal setting running
time.

The VFD will report
overload pre-alarm
according to the set value.

The keypad is not in good
connection or offline;

The keypad cable is too
long and there is strong
interference;

Part of the communication
circuits of the keypad or
main board have fault.

Solutions

Check the PID feedback
signal wire;

Check the PID feedback
source.

Check the braking unit and
change to new brake pipe;

Increase the braking
resistor.

Ask for the supplier and
adjust the setting running
time.

Check the load and the
overload pre-alarm point.

Check the keypad cable
and ensure it is normal;

Check the environment
and eliminate the
interference source;

Change hardware and ask
for maintenance service.
