Fault
code
Description
Cause Solution
0012
Overcurrent of pump motor
1. Encoder fault or circuit
interference;
2. Motor UVW short-
circuited;
3. Mismatched motor
parameters;
4. Controller fault.
1. Check the encoder surface for stains, re-
place it if necessary;
2. Check the motor UVW 3-phase cable for
short circuit or damage, and check the
controller UVW 3-phase cable for damage
using a multimeter;
3. Monitor the controller current when fully
loaded, re-match the motor if necessary;
4. If no problem is found in the above inspec-
tions, 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 UVW 3-phase cable for short
circuit or current leakage;
2. If no problem is found in the above inspec-
tions, replace the controller.

Pre-charging fault of pump
motor controller
1. Voltage drop due to
loads connected to B+
circuit;
2. Controller damaged.
1. Check whether other high-power loads are
connected to the controller B+ circuit;
2. Check the KSI wiring, and measure the
voltage using a multimeter to check for
abnormality;
3. If no problem is found in the above inspec-
tions, replace the controller.
