4.6.18 Self-assembled encoder cables
If self-assembled encoder cables are used, make sure to dimension the connector and
the route the cable in a way that the safety cover of the application inverter can be
closed.
The maximum permitted width of the connector is 16mm.
The maximum permitted height of the connector up to the highest point of the cable
routing is 46mm.

Minimum requirements for encoder cables
Make sure that self-assembled cables fulfilled the following requirements:
• Cross section of voltage supply cable:
– At least 0.25mm
2
for cable lengths up to 50m.
– At least 0.5mm
2
for cable lengths up to 100m.
• Cross section of the signal wire:
– At least 0.25mm
2
.
• Capacitance per unit length:
– Maximum 70 pF/m - core/core.
– Maximum 120 pF/m - core/shield.
• The cable must be shielded.
• Differential signals must be routed via twisted wires e.g. Data+ and Data-.
