Do not connect a load power supply to pin 20. The connection provides a shortĆcircuitĆ
proof power supply of the contact at pin 1. In S5Ć115, use the adapter casing and conĆ
nect the lines at pins 21 through 37 0 V (M bar), i.e. reference potential.
Without leaving a gap, the 17 digital outputs are assigned consecutively as two- or three-step
controllers according to the configuration. The number of controllers is limited by the digital out-
puts required (maximum 17).
Typical controller assignment
Required: Cascaded control with closed-loop controllers 1, 2, and 3 as three-step controllers
and closed-loop controllers 4, 5, and 6 as two-step controllers. All other controllers are disabled.
