Fault Name
6-4
Fault Descriptions
Broken fuse
The fuse at DC side
is broken for 30hp
and below
Electronic Thermal
Relay 1/2 Protection
These two fault codes
will be displayed
when output current
exceeds the level of
over-torque detection
(Pr.06-08 or Pr.06-
11) and it is set 2 or 4
in Pr.06-06 or Pr.06-
09.
Internal EEPROM
can not be
programmed.
Internal EEPROM
can not be read.

External Fault
Corrective Actions
1. Check whether the fuse of the transistor
module is functioning well
2. Check whether the loading side is short-
circuit
1. Check whether the motor is overloaded.
2. Check whether motor rated current
setting (Pr.05-01) is suitable
3. Check electronic thermal relay function
4. Take the next higher power AC motor
drive model.
1. Press "RESET" key to the factory setting
2. Return to the factory.
1. Press "RESET" key to the factory setting
2. Return to the factory.
Re-power on to try it. If fault code is still
displayed on the keypad please return to the
factory
Re-power on to try it. If fault code is still
displayed on the keypad please return to the
factory
1. Check cabling between drive and motor
2. Retry again
1. Check the wiring of the PID feedback
2. Check the PID parameters settings
Check if Pr.10-01 is set to 0 when it is PG
feedback control
Check the wiring of the PG feedback
1. Check the wiring of the PG feedback
2. Check if the setting of PI gain and
deceleration is suitable
3. Return to the factory
1. Check the pulse wiring
2. Return to the factory
1. Check the ACI wiring
2. Check if the ACI signal is less than 4mA
1. Input EF (N.O.) on external terminal is
closed to GND. Output U, V, W will be
turned off.
2. Give RESET command after fault has
been cleared.
