Possible Reasons Solutions
Fu.13 Motor overload
1. The load is too large.
2. The acceleration time is
too short.
3. The protection factor
Setting is too small.
4.
The torque boost is too
high.
1. Reduce load.
2. Extend the acceleration
time.
3.
Increase the overload
protection factor of motor.
4. Reduce torque boost.
Fu.14 Inverter overheat
1. Air duct obstruction
2. The environment
temperature is too high.
3. The fan is damaged.
1. Clean air duct or improve
ventilation condition.
2. Improve the ventilation
condition and reduce the
carrier frequency.
3. Change fan.
Fu.15 Reserve
Fu.16
External
equipment fault
The exterior fault input
terminal is ineffective.
1. Check the exterior
equipment.
2. Disconnect the external
fault input terminal.

Fu.20
Current
detection error
The current detection
devices or circuit is
damaged.
1. Check socket line.
2. Ask for manufacturers’
assistance.
Fu.21
Temperature
sensor fault
The temperature sensor is
off-line.
1. Check socket line.
2. Ask for manufacturers’
assistance.
Fu.22 Reserve
Fu.23
PID feedback
off-line
1 The feedback signal is
lost.
2. The setting of off-line
detection threshold value
is not appropriate.
1. Check line.
2. Reduce threshold value of
off-line detection.

7.2 Fault record query
The series of inverters recorded the recent fault code occurred in the last four
times and the inverter output parameters of the last fault; query of these
information will contribute to find fault causes.
