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 set in 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.

Run Command Selection 2
Sets the input method for Run Command 2 when the user switches the control circuit terminals ON/
OFF to change the Run command source.
0
(0 - 3)
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.
1 : Digital Input
Use the control circuit terminals to enter the Run command. Select the input method for the Run command with an
H1-xx parameter.
Set H1-xx = 0, 40 to 43 [3-Wire Sequence, Run Command (2-Wire Sequence)] . The default setting is 2-wire sequence
1.
• 2-wire Sequence 1
This sequence has two input types: FWD/Stop and REV/Stop. Set
A1-03 = 2220 [Initialize Parameters = 2-Wire
Initialization] to initialize the drive and set terminals S1 and S2 for a 2-wire sequence.
• 2-wire Sequence 2
This sequence has two input types: Run/Stop and FWD/REV.
•
3-Wire Sequence
This sequence has three input types: Run, Stop, and FWD/REV. Set
A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] to initialize the drive and set terminals S1, S2, and S5 for a 3-wire sequence.
2 : Memobus/Modbus Communications
Use MEMOBUS/Modbus communications to enter the Run command.
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 b1-16 = 3 but no option card is connected, then oPE03 [Multi-Function Input Setting Err] will flash on the keypad.

Run Command at Power Up
Sets drive response when energizing a drive that has an external Run command. Set this parameter in
applications where energizing or de-energizing the drive enables the Run command.
0
(0, 1)
0 : Disregard Existing RUN Command
The drive does not start to operate the application when the power is switched ON, even when there is an existing Run
command.
