ACS880 Drives Noise on analogue signals
Dear All,
When i connect analogue signals from ACS880-34 drives to PLC, all the analog signals in the plc gets disturbed.
Is there any way to stop the drive from producing that noise? or at least isolate it from my plc ?

Hi,
You have to provide more information about your application, type of signals, connections, size of drive etc. in order to receive more precise answer.
Basically, if you follow the instructions in the drive manual for cabling, power and control cables (shielded cables), earthing as requested and using of 4-20mA analogue signals, you shouldn't have a problems with disturbances. In some cases you may need EMC filter at input of the drive.
But you should look on earthing and shielded cables first.
