I have an ACS 600 drive for motor control. The drive receives a 4-20mA input from a PLC at terminal AI2. The 4-20mA signal changes but the Motor runs at constant maximum speed displaying AI2[mA]=20.3mA.
Could someone explain to me why the drive is ignoring the mA input from the PLC? Can 21.1 which is set to DC MAGN be a factor?
NB: I have set 11.3=AI2;Min AI2=4mA;Maximum AI2=20mA
