Single-axis controllers Control terminals 4 4.7 Analog inputs, analog outputs The controller features two analog inputs which are able to detect differential voltage signals in the range ±10 V, e.g. an analog speed setpoint selection or the voltage signal of an external sensor (temperature, pressure, etc.). ƒ The analog signal 1 can also detect a current setpoint. The controller features two analog outputs, which can output internal analog signals as voltage signals, e.g. for the control of analog indicating instruments or as a setpoint for slave drives.
