Encoder Wiring - Parker FL20-CA Series Product Manual

4.2 Encoder wiring

Precautious of encoder wiring:
 Ground the servo drive and shielded layer of the servo motor reliably. Otherwise, the servo
drive will report a fault alarm;
 Do not connect to "NC" terminal;
 To determine the length of the encoder cable, consider voltage drop caused by the cable
resistance and signal attenuation caused by the distributed capacitance.
 Encoder cable and power cable must be separately by at least 30cm;
 If encoder cable needs to add another cable because of short, make sure that the shielded
layer and grounding are connected reliably
