2. Set H6-02 [Terminal RP Frequency Scaling] to the number of pulses that determine 100% of the frequency
reference.
3. Enter a pulse train signal on the terminal RP and make sure that the keypad shows a correct frequency
reference.

Run Command Selection 1
Sets the input method for the Run command.

(0 - 3)
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 on the keypad is on while keypad is the Run command source.
1 : Analog 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 b1-02 = 3, but you did not connect a communications option card, oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the
keypad.

Stopping Method Selection
Sets the method to stop the motor after removing a Run command or entering a Stop command.
0
(0 - 3, 9)
Note:
When A1-02 = 5, 6, 8 [Control Method Selection = OLV/PM, AOLV/PM, EZOLV], the setting range is 0, 1, 3.
Select the applicable stopping method for the application from these four options:
0 : Ramp to Stop
When you enter the Stop command or turn OFF the Run command, the drive ramps the motor to stop.
The drive ramps the motor to stop as specified by the deceleration time. The default setting for the deceleration
time is C1-02 [Deceleration Time 1]. The actual deceleration time changes as the load conditions change (for
example, mechanical loss and inertia).
If the output frequency is less than or equal to the value set in b2-01 [DC Injection/Zero SpeedThreshold] during
deceleration, the drive will do DC Injection Braking, Zero Speed Control, or Short Circuit Braking, as specified
by the control method.
