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 connected to the drive to enter the Run command.
Refer to the instruction manual included with the option to install and set the option.
Note:
If b1-01 = 3 but you did not connect an option, oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the keypad.
