Fault
code
Description
Cause Check
0012
Overcurrent of pump motor
1. Encoder fault or circuit
interference;
2. There is a short to
Motor UVW;
3. Mismatch of motor
parameters;
4. Controller fault
1. Check the encoder surface for stains,
replace if necessary;
2. Check whether the 3–phase of motor
UVW is shorted or damaged, check the
controller UVW 3–phase for damage using
a multimeter;
3. Monitor the controller current when fully
loaded, re-match the motor if necessary;
4. If the above checks fail, replace the
controller.

Current sensor fault of
pump motor controller
1. Motor UVW short-
circuited;
2. Current sensor of the
controller faulted
1. Check the 3–phase cable of UVW for short
circuit or current leakage;
2. If the above check fails, replace the
controller.

Current sensor fault of RR
motor controller
0014
Pre-charging fault of pump
motor controller
1. The voltage reduces
due to loaded B+
circuit;
2. Controller damage.
1. Check whether the controller B+ circuit is
linked to high-power load;
2. Check the KSI wiring, and measure the
voltage using a multimeter to check if it is
normal;
3. If the above checks fail, replace the
controller.

Low temperature of pump
motor controller
The controller operates at
ambient temperatures
below –40 ℃.
1. 1. Raise the ambient temperature above–
40 ℃, restart the key switch and interlock
switch;
2. If the above checks fail, replace the
controller.
