5.2 Analog inputs
The regenerative power supply module has two analog inputs which can be used to detect
differential voltage signals in the range of ±10 V, for instance an analog speed setpoint
selection or the voltage signal of an external sensor (temperature, pressure, etc.).
 Optionally, analog input 1 can also be used to detect current setpoints.
