Changing between Master and Auxiliary Frequency References
Use the multi-step speed reference function to change the frequency reference input between terminals A1 and A2.
2 : Memobus/Modbus Communications
Use MEMOBUS/Modbus communications to enter the frequency reference.
3 : Option PCB
Use a communications option card connected to the drive to enter the Run command.
Refer to the instruction manual included with the option card to install and set the option card.
Note:
If you set b1-15 = 3 but you do not connect an option card, oPE03 [Multi-Function Input Setting Err] will flash on the keypad.
