Fault
code
Description
Cause Solution
3. Check the coil of contactor;
4. Replace the solenoid brake.
Note: The pin #4 of the 35-pin controller
connector is for driver 3 output.

solenoid brake/coil 3 output
of RL motor controller
0433
Open/short-circuited
solenoid brake/coil 3 output
of RR motor controller

Open/short-circuited coil 4
output of pump motor
controller
1. Open/short-circuited
coil 4;
2. Stained/damaged/bro-
ken wiring.
1. Check if the wiring is correct and pins are
stained or damaged;
2. Monitor output signal (monitor menu/out-
puts menu/Driver 4PWM) to check
whether there is output control signal;
3. Check the driver coil.

Proportional drive error of
pump motor controller
1. Open/short-circuited
loading device;
2. Stained/damaged/bro-
ken wiring;
3. Improper wiring.
1. Check if the wiring is correct and pins are
stained or damaged;
2. Monitor output signal “monitor menu/out-
puts menu/PD PWM” to check whether
there is output control signal;
3. Check the loading devices, such as the
driver coil, for damage.

0036
Encoder error of pump
motor controller
1. Failed power supply of
encoder;
2. Damaged encoder;
3. Improper wiring.
1. Check the encoder power supply;
2. Check the pulse count of encoder setup
(programme/motor menu/encoder steps);
3. Check the encoder feedback speed sig-
nals (monitor/motor menu/motor speed A/
B);
4. If the inspections above fail to discover the
problem, replace the motor.
Note: The pins #31 and #32 of the 35-pin
controller connector are for encoder AB phase
output signals.

Open-circuited pump motor
controller
1. Missing phase in
motor;
2. Improper wiring;
1. Ensure the UVW 3-phase wiring not open-
circuited;
2. Use a multimeter to check the UVW power
