Fault Name
Cause
Possible Solution
9. Excessive torque
compensation
10. Electrical signal
interference causes drive
malfunction
11. Overexcitation gain is set
too high
12. Run command was
applied while motor was
coasting
13. Incorrect motor code
14. The motor does not
match the drive control
method
15. The motor cable is too
long
8. Check the ratios between the
frequency and voltage set by
V/F.
9. Adjust d1-02 to d1-11 (or d1-
13 to d1-22 for motor 2)
10.Check the amount of torque
compensation
11. Find out possible solutions
to suppress the electrical signal
interference
11. Check if the fault occurs
frequently with overexcitation
function operation
12. Enable Speed Search via
multi-function input terminal
14. Check the control method
(A1-02)
15. Use a larger drive

IGBT Fault or Output
Short Circuit
1. Motor has been damaged
due to the motor insulation
weakened or overheat
2. The cable is damaged
3. Hardware fault
4. The drive is damaged
1. Replace the motor or check
the motor insulation resistance
2. Repair any short circuits and
check the motor power cable

External Fault
（Input Terminal S1
to S6）
1. An external device tripped
an alarm
2. Incorrect wiring
3. Multi-function input
wiring is not correct
1. Remove the cause of the
external fault then reset the
multi-function input.
2. Confirm if the signal lines is
properly connected to the
terminals assigned for external
fault detection (E1-口口= 23 to
38)
3. Confirm if E1-口口=23 to 38 is
set to the unused terminals.

temperature over 95
°C
1. Ambient temperature is
too high
2. Internal cooling fan
stopped operating
3. Bad air flow due to
insufficient room.
1. Check the temperature
surrounding the drive
a. Improve the air flow inside the
enclosure panel
b. Install an air conditioner or fan
to cool the environment
c. Remove any possible source of
