Open loop control: control value by external signal 4…20mA
A fixed speed of 2000 1/min should be given by an external signal 4…20mA at analog input 1.
The feedback of the speed should be send by analog output to a PLC.
2000 1/min is equal to 14,85 mA when using a 2-pole motor with a nominal speed of 2950 1/min (16mA / 2950 rpm * 2000 rpm + 4 mA
= 14,85 mA). Information: the set point can’t be lower than the minimum speed
