Changing between master and auxiliary frequency references
Use the multi-step speed reference function to change the frequency reference input between terminals A1, A2,
and A3.
2 : Memobus/Modbus Communications
Use MEMOBUS/Modbus communications to enter the frequency reference.
3 : Option PCB
Use a communications option card or input option card connected to the drive to enter the frequency reference.
