The cable type for SS-encoders must be chosen acc. to the specification
of the encoder manufacturer. Thereby please observe the following
boundary conditions:
• Always used shielded cables. The shielding must be placed on both
sides of the cable.
• Connect the differential track signals A, B or CLK, DATA to each
other via twisted wires.
• Do not separate the encoder cable, for example to route the signals
via terminals in the switch cabinet.
