Hi guys,
I am looking for advice,
I have a 1kw ac servo motor. the encoder is connected to the driver and they work well. the driver reads the encoders position well.
when trying to read the encoder pulses from the driver to my arduino, i get a lot of noise, i.e, i get pulses even when the motor is not turning.
I tried to use different cables. I got a cat7 cable. and as per to the illustration hooked up the couples of twisted cables to each signal and ground (they are all grounded at the arduino side only).
1. Should the outer braid be soldered to the connector at the driver side?
2. Do i need to connect also the inner naked wire ?
3. Should I connect it to the earth ground ? This is what I understand from the illustration (down left "FG")
4. On the arduino side, should i connect the shield to the ground pin ?
5. Not all wires are connected, can this cause a problem ?
6. Should i connect the arduino ground with the 12v power supply (of the servo) ground ?
Thank you.
