3.3
Using an external motor drive
To use an external motor drive rather than the internal KCM motor
drive, do the following:
1. The AC Interface drive board is installed.
2. In the ANALOG OUTPUT sub-menu, set the following:
– <ANALOG NUM>: <CPU>
Note:
The CPU outputs 0-20 mA only.
– <FUNCTION>: <Drive Command>
– <DEADBAND>: <0.25>
– <AOUT MAX>: 100% (This is the output span value)
– <AOUT MIN>: 20% (This is the offset value)
3. Make the wiring connects per the provided drawing.
4. Run the feeder in volumetric control.
5. Adjust <Aout Max> to get the desired motor speed for a given
value of drive command.
