Fault
code
Description
Cause Solution
0424
Reduced overvoltage
performance of RR motor
controller
0025
Invalid 5V internal power
supply of pump motor
controller
Externally connected
device fault
1. Check the externally connected device for
damage;
2. Using handhold unit check the device
(monitor/outputs menu/5 Volts);
3. Disconnect externally connected 5V devi-
ces, if the fault still exists, replace the ex-
ternal devices.
Note: The pin #26 of the 35-pin controller
connector is for 5V output.

Invalid 5V internal power
supply of FL motor controller
0225
Invalid 5V internal power
supply of FR motor
controller
0325
Invalid 5V internal power
supply of RL motor
controller

Driver 6 output error of
pump motor controller
Externally connected
device fault
1. Using handhold unit, monitor the output
(monitor/digital out6) to find out the driver
6 signal output percentage;
2. Check the drive device of driver 6 for mal-
functions, correct wiring, and current not
exceeding 1A.
Note: The pin #19 of the 35-pin controller
connector is for driver 6 output.

Driver 6 output error of FL
motor controller
0226
Driver 6 output error of FR
motor controller
0326
Driver 6 output error of RL
motor controller
0426
Driver 6 output error of RR
motor controller
0027
Driver 7 output overcurrent
of pump motor controller
Externally connected
device fault
1. Using handhold unit, monitor the output
(monitor/digital out7), to inspect the driver
7 signal output percentage;
2. Check the drive device of driver 7 for mal-
functions, correct wiring, and current not
exceeding 1A.
Note: The pin #20 of the 35-pin controller
connector is for driver 7 output.
0127
Driver 7 output overcurrent
of FL motor controller
0227
Driver 7 output overcurrent
of FR motor controller
0327
Driver 7 output overcurrent
of RL motor controller

Reduced overheat
performance of RR motor
controller
0028
Reduced overheat
performance of pump motor
controller
1. Motor temperature
reaching the preset
limit;
2. Improper motor tem-
perature setup.
1. Check the motor temperature sensor for
damage;
2. Check the overheat performance attenua-
tion value setup (programme/motor menu/
temperature control temperature hot) for
error;
3. Monitor the machine operating current to
determine whether the overheat results
from an excessively high current, re-match
