546 SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
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 b1-02 = 3 but no connected option card, then oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the keypad.

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 : 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, the light on the keypad will flash quickly if the Run command is already enabled from an external
source.
2 : Disregard 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 using a 3-Wire sequence:
• Set the drive for 3-Wire sequence.
• Set b1-17 = 1 [RUN@PowerUp Selection = Disregard RUN]
• Wire the drive for 3-Wire sequence.
If these three conditions are correct, the motor can rotate in reverse when energizing the drive:
• The drive is wired for 3-Wire sequence.
• The drive is set for a 2-Wire sequence (default).
• b1-17 = 2 [RUN@PowerUp Selection = Accept RUN]
Failure to obey can cause death or serious injury from moving equipment.

Sets drive response to a Run command when A1-02 = 3 or 7 [Control Method = CLVector or PM
CLVector] . Usually it is not necessary to change this setting.

(1, 2)
1 : Reject RUN
When motor speed ≥ b2-01 or motor speed < E1-09 , the drive will not accept a Run command.
2 : Accept RUN
When motor speed ≥ b2-01 or motor speed < E1-09 , the drive will accept a Run command.
