Cable type and configuration [X2]
As only short cables are used for the motor installation variant, shielded and twisted
cables can usually be omitted. However, the cables must not exceed a maximum length
of 80 mm. For the encoder supply US and GND we recommend a minimum cross-section
of 0.25 mm², for all other cables a cross-section of 0.14 mm².
