Single-axis controllers Control terminals 4 4.7 Digital inputs The drive controller is equipped with freely configurable digital inputs. ƒ The following digital inputs are with touch-probe capability (edge-controlled event)): – ”HighLine”: all inputs – ”StateLine”: DI1 ƒ The control input RFR for controller enable is firmly connected with the device control. It must be wired to enable the controller with a HIGH signal. Note! Digital inputs and digital outputs have separated reference potentials (GI and GO). If you interconnect inputs and outputs, the reference potentials are connected as well by an external bridge.
