SIEPCYEUOQ2V01A Q2V Technical Manual 453
Note:
The is on while the 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 FWD/REV Cmd, 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
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 b1-16 = 3 but no option card is connected, then oPE03 [Multi-Function Input Setting Err] will flash on the keypad.
■ b1-17: RUN@PowerUp Selection
No.
(Hex.)
Name Description
Default
(Range)
b1-17
(01C6)
RUN@PowerUp Selection
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.
1
(1, 2)
1 : Disregard RUN
The drive does not start to operate the application when the power is switched ON, even when there is an existing
Run command.
Enter the Run command again to operate the application.
Note:
When you energize the drive, on the keypad will flash quickly if the Run command is already enabled from an external source.
2 : Accept RUN
When there is an existing Run command, the drive starts to operate the application when the power is switched
ON.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Init Parameters = 3-Wire
Initialization] and make sure that b1-17 = 1 [RUN@PowerUp Selection = Disregard RUN] (default). If you do not correctly set
the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in reverse when you
energize the drive.
■ b1-35: DI Deadband Time
No.
(Hex.)
Name Description
Default
(Range)
b1-35
(1117)
Expert
DI Deadband Time
Sets the deadband time for MFDIs.
0.0 ms
(0.0 to 100.0 ms)
When the on/off time for MFDIs is longer than the time set in b1-35, the drive activates the MFDI. Set this
parameter to prevent malfunctions caused by relay chattering for applications in which relays send input to MFDI
terminals.
