6.1 Fault code and reason analysis
The protection circuit and fault output relay activates, and stop the
machine and show failure, after the cabinet detects abnormal situations.
Make sure to find the failure causes and countermeasures, and run the
cabinet after troubleshooting.
The cabinet will record last 3 times causes of the malfunction. After
fault reset, you can check records any time in group E in viewing
functional parameters (Parameters FA.14~FA.16). For fault codes
description, please check Table 6-1.

oC1
oC2
oC3
Over-current
in operation
Output short circuit
or mutation load
Please identify reasons,
and reset after taking
approximate measures. If
this is still on, please ask
for technical support.
oC2
Over-current
in accel
1. The setting value
of accel time is too
small; 2. Torque
compensation
voltage value is set
in an error.
1. increase accel time
value;
2. increase or decrease
torque compensation
voltage value
oC3
Over-current
in decel
1. The setting value
of decel time is too
small;
2. Output short or
load mutation.
1. increase decel time
value;
2. eliminate short-circuit or
load mutation
oE1
Over-voltage
in accel
oE3
Over-voltage
in operation
1.Power voltage is
too high; 2.load
speed has fluctuated
1.Make sure that the power
voltage is in the normal
range;
2. Decrease fluctuation of
load speed.
