Inverter alarm a043, how is it
When there is a signal failure, if necessary, use DTI
Board, if necessary, change P215
In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
When a signal failure occurs, use the DTI board, if necessary, change P215. With P806
(Follow the parameter description) during operation can be converted to no encoder operation
A043 is: n-actjump exceeds the allowable change speed of the speed encoder signal (P215)
In addition, for the synchronous motor (P095 = 12):
The motor speed is 2% higher than the inverter release time point.
The inverter in the ready state can not exit. Check processing:
Check if the cable is disconnected
Check the tachometer to shield the ground
Not only on the motor side but also on the inverter side
The encoder cable does not allow disconnection
Use only recommended encoders
The encoder cable is not allowed to be laid with the power cable
Check processing:
Check if the cable is disconnected.
Check the tachometer to shield the ground.
The shield is not only on the motor side, but also on the inverter side
The cable of the pulse encoder should not be disconnected.
The pulse encoder cable can not be laid together with the power loop cable.
Use only the recommended pulse encoder.
