4.2 Encoder wiring
Precaution for encoder wire:
1. Make sure servo drive and motor are grounded reliably, otherwise servo drive may have wrong action.
2. Don’t connect encoder cable to NC terminal.
3. User must consider of cable resistance and distributed capacitance to select cable length.Cable resistance may
cause voltage drop, distributed capacitance will lead to signal attenuation,
4. Encoder cable and power cable must be fixed separately, with at least 30cm distance.
5. If encoder cable is not long enough and needs to connet additional cable, cable shielding layer must be also
connected to ensure reliable shielding and grounding.
