Fault
code
Description
Cause Solution
0015
Low temperature of pump
motor controller
The controller operates at
ambient temperatures
below -40 ℃.
1. Raise the ambient temperature above -40
℃, restart the key switch and interlock
switch;
2. If no problem is found in the above inspec-
tions, replace the controller.
0115
Low temperature of FL
motor controller
0215
Low temperature of FR
motor controller
0315
Low temperature of RL
motor controller
0415
Low temperature of RR
motor controller
0016
High temperature of pump
motor controller
1. Controller temperature
over 95℃;
2. Machine overloaded
and motor non-
matched;
3. Controller damaged.
1. Check the cooling measures of controller;
2. Monitor the operating current of controller
(monitor/controller menu/current), re-
match the motor if the current is too high,
reset the turning point and slip value, prop-
erly restrict the current if needed.
3. If no problem is found in the above inspec-
tions, replace the controller.
0116
High temperature of FL
motor controller
0216
High temperature of FR
motor controller
0316
High temperature of RL
motor controller
0416
High temperature of RR
motor controller
0017
Severe undervoltage of
pump motor controller
1. Battery data setup
error;
2. Excessive battery
resistance;
3. Damaged fuse;
4. Damaged main
contactor.
1. Measure the battery voltage and KSI and
B+ circuits voltage with a multimeter;
2. Check the fuse and contactor;
3. Check the battery system voltage (pro-
gramme/battery menu nominal voltage)
and (user undervoltage) undervoltage
setting.
4. If the drive controller fails, main contactor
not engaged, the pump controller will re-
port the fault 1.7.

Severe undervoltage of FL
motor controller
0217
Severe undervoltage of FR
motor controller
0317
Severe undervoltage of RL
motor controller
0417
Severe undervoltage of RR
motor controller
0018
Severe overvoltage of pump
motor controller
1. Battery data setup
error;
2. Excessive battery
resistance;
3. Battery disconnected
when regenerative
brake engages.
1. Check the battery with a multimeter for
proper voltage;
2. Check the fuse and contactor;
3. Check the battery system voltage (pro-
gramme/battery menu nominal voltage)
and (user undervoltage) undervoltage
setting.
4. Check the regenerative brake current limit
setting (programme/current limits menu re-
gen current limit).
0118
Severe overvoltage of FL
motor controller
0218
Severe overvoltage of FR
motor controller
0318
Severe overvoltage of RL
motor controller
0418
Severe overvoltage of RR
motor controller
0021
Declined battery current of
pump motor controller
Activated battery current
attenuation
The power generation current limit value
sent by the host computer is less than the
actual value.
