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

Run Comm. Sel 1
Sets the input method for the Run command.
1
(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 = 1 to 5 [Forward Run to 3-Wire Seq.] . 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 [Init Parameters = 2-Wire
Initialization] to initialize the drive and set terminals DI1 and DI2 for a 2-wire sequence.
•
2-wire Sequence 2
This sequence has two input types: Run/Stop and FWD/REV.
• 3-Wire Sequence (3-Wire Seq.)
This sequence has three input types: Run, Stop, and FWD/REV. Set
A1-03 = 3330 [Init Parameters = 3-Wire
Initialization] to initialize the drive and set terminals DI1, DI2, and DI5 for a 3-wire sequence.
2 : Modbus
Use 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 no connected option card, then 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 = PM OLVector, PM AOLVector, EZ Vector] , the setting range is 0, 1, 3.
Select the applicable stopping method for the application from these four options:
0 : Ramp->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 [Decel 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 [ZSpd/DCI Threshold] during deceleration,
the drive will do DC Injection Braking, Zero Speed Control, or Short Circuit Braking, as specified by the control
method.
•
Ramp to Stop with V/f Control and OLV Control Methods
Parameter b2-01 sets the frequency to start DC Injection Braking at stop. If the output frequency is less than or
equal to the value set in b2-01 during deceleration, then the drive will perform DC Injection Braking for the
time set in b2-04 [DCInj Time@Stop] .
