Note:
You can also use this diagram to wire terminal A1.
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 : Serial Communications
The drive uses serial communications to enter the frequency reference.
3 : Option PCB
The drive uses a communications option card or input 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 b1-01 = 3, but you did not connect a communications option card, oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the keypad.
