User Manual of SY5000 series AC Drive Toubleshooting
~91~
Over-heat
protection (o.t.)
Detect the temperature of radiator, cut off output and shut down when it
is approximately 85
℃
Self-diagnosis
(-.Err)
Detecting interior CPU, peripheral circuit and data storage is normal, or
not.
7.2 Fault code and reason analysis
The inverter records latest four fault reasons. After fault reset, you can view
(E-010~E-013) in group E of function parameters any time. Insturction of fault code
is as shown in Table 7-2.

Troubleshooting
Over-current
in operation
Output short circuit or
mutation load
Please identify reasons,
and reset after taking
approximate measures. If
this persists, please seek
technical support.
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
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
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.
Over-voltage
in accel
Over-voltage
in decel
Load inertia (GD2) is
too big
1. To change the decel
time so that it is suitable
for the load inertia;
2. connect braking unit
