R/W error occurred to the
control parameters;
EEPROM is damaged
PID feedback offline;
PID feedback source
disappears;
Braking circuit fault or
braking tube is damaged;
fault The resistance of external
braking resistor is too small
The actual running time of
the VFD is larger than the
up
set running time
The VFD releases overload
pre-alarm based on the set

Troubleshooting
Corrective measures
Press STOP/RST to reset;
Replace the main control board
Check PID feedback signal
wires;
Check PID feedback source
Check the braking unit, replace
with new braking tubes;
Increase braking resistance
Ask help from the supplier,
adjust the set running time
Check the load and overload
pre-alarm threshold
Check the keypad wires to
confirm whether fault exists;
Check the surroundings to rule
out interference source;
Replace the hardware and ask
for maintenance service
