6.3.3.3 Encoder cable
General information on connecting encoder cables:
• Use encoder cable double shielded and twisted in pairs.
• Connect outside shield to GND at both ends. At the drive controller 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!
