7.2 Analog inputs
The controller has 2 analog inputs that can be used to detect differential voltage signals in
the range of ±10 V, e.g. analog speed setpoint selections or the voltage signals of an
external sensor (temperature, pressure, etc.).
r Optionally, analog input 1 can also be used to detect current setpoints.
