PIDE
abnormal
1. The capacitr of inverter
and motor is not enough.
2. Setting PID target
value and feed-back
value unreasonable
3. peripheral equipment
failure
1. Exchange a larger capacity
inverter and motor.
2. Check the value which setting
of PID feel-back signal Gain
setting the value again
according to PID feed-back
signal Gain.
3. Check whether the external
feedback device (such as
sensor, regulation resistance)
and circuit is normal or
abnormal.
NTC
The IGBT
module is
overheating
The temperature of IGBT
module is too high
1. Reduce the environment
temperature and improve the
air condition
2. Check whether the fan of the
inverter is damaged.
CPR
CPU abnormal
CPU software abnormal
1. Check the wiring.
2. Check the parameter setting.
3. Improve external disturbance.
OL2
Over torque
abnormal
1. Too heavy load of motor.
2. The setting value of
P.155 and P.156 is
unreasonable.
1. Alleviate the load of motor.
2. Adjustment the setting value
of
P.155
and
P.156
properly
AErr
Abnormal of
4-5 terminal
The disconnection abmormal
when simulation given of 4-5
terminal.
Please refer to the parameter
P.184
.
Note: 1. When the above alarms occur, the inverter will stop. Please deal with these alarms according to the
methods mentioned above.
2. The abnormal number of alarm code can refer to
P.288~P.291
.
