ID No.
Display Descriptions
22
Electronics thermal relay 1 protection.
Corrective Actions
 Check the setting of electronics thermal relay (Pr. 06-14)
 Take the next higher power AC motor drive model.
23
Electronics thermal relay 2 protection.
Corrective Actions
 Check the setting of electronics thermal relay (Pr. 06-28)

Take the next higher power AC motor drive model.
24
Motor overheating.
The AC motor drive detecting internal temperature exceeds the setting of
Pr. 06-30 (PTC level)
Corrective Actions
 Make sure that the motor is not obstructed.
 Ensure that the ambient temperature falls within the specified
temperature range.
 Change to a higher power motor.
26
When the output current exceeds the over-torque detection level (Pr. 06-07 or
Pr. 06-10) and also exceeds Pr. 06-08 or Pr. 06-11, when Pr. 06-06 or Pr.
06-09 is set as 1 or 3, it will display warning without abnormal record; when
Pr. 06-06 or 06-09 is set as 2 or 4, it will display error, stop running and there
will be an abnormal record.
Corrective Actions
 Check if motor is overloaded.
 Check Pr. 05-01 motor rated current is correct or not.
 Increase motor capacity.
27
28
Low current detection.
Corrective Actions
 Check Pr. 06-71, Pr. 06-72, Pr. 06-73.
31
Internal EEPROM can not be read.
Corrective Actions

Press “RESET” key to the factory setting.
 Return to the factory if it invalid.
33
U-phase current error.
Corrective Actions
 Reboots the power.
 If fault code is still displayed on the keypad please return to the factory.
34
V-phase current error.
Corrective Actions
 Reboots the power.

If fault code is still displayed on the keypad please return to the factory.
