4.3.7.3 Encoder cable
General information on connecting encoder cables:
• Use encoder cable double shielded and twisted in pairs
• Connect outside shield to PE/GND at both ends. At the inverter end, connect outside
shield either
- onto the shield connection rail using shield connection clamps or
- to the housing of the SubD plug (connect inside the plug).
• •Connect interior shielding at one side at the inverter to COM
• do not connect outside and inside shield
