8.2 Analog inputs

The controller has two 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.).

• Optionally, analog input 1 can also be used to detect current setpoints.
