Figure 12.23 Example of Setting the Frequency Reference with a Current Signal to Terminal A2
Note:
You can also use this diagram to wire terminals A1 and A3.
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 Run command.
Refer to the instruction manual included with the option card to install and set the option card.
Note:
If b1-15 = 3 but no option card is connected, then oPE03 [Multi-Function Input Setting Err] will flash on the keypad.
4 : Pulse Train Input
Use a pulse train signal from the pulse train input terminal RP to enter the frequency reference.
Do this procedure to make sure that the pulse train signal is operating correctly.
1. Set b1-15 = 4, H6-01 = 0 [Terminal RP Pulse Train Function = Frequency Reference].
2. Set H6-02 [Terminal RP Frequency Scaling] to the number of pulses that determine 100% of the frequency
reference.
3. The terminal assigned to H1-xx = 2 [MFDI Function Selection = External Reference 1/2 Selection] is activated.
4. Enter a pulse train signal on the terminal RP and make sure that the keypad shows a correct frequency reference.

Activate H1-xx = 2 [MFDI Function Selection = External Reference 1/2 Selection] to enable this parameter.
0 : Keypad
Use the keypad to enter the Run command.
You can use the JOG operation or the FWD/REV commands from the keypad.
Note:
The is on while the keypad is the Run command source.
