6.5 Setpoint sources
6.5.1 Analog inputs
Description
The customer terminal block TM31 features two analog inputs for specifying setpoints for
current or voltage signals.
In the factory setting, analog input 0 (terminal X521:1/2) is used as a current input in the
range 0 to 20 mA.
Prerequisites
The default setting for analog inputs was chosen during commissioning:
• STARTER:
"TM31 Terminals"
• AOP30:
"2: TM31 terminals
