Omron Q2A Series Technical Manual page 523

When the drive is operating the motor, turn OFF the Run command to stop the motor. Enter the Run command
again to start operation.
2 : Accept RUN
If a Run command is enabled when you switch between Run command sources, the drive will start to operate the
motor or continue to operate the motor.
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.

Selection
(0187)
As a safety precaution, when the drive is in Programming Mode, it will not respond to a Run command.
This parameter helps prevent accidents that can occur if the motor starts to rotate because the drive received a Run
command from an external source while the user is programming the drive. You can also set the drive to not show
the Programming Mode when a Run command is active.
1 : NoRUN@Program
The drive rejects the Run command while in Programming Mode.
2 : RUN@Program
The drive accepts a Run command entered from an external source while in Programming Mode.
3 : Program@Stop only
The drive does not let the user enter Programming Mode when the drive is operating. The drive does not show the
Programming Mode when a Run command is active.

Forward Run command from the drive and the forward direction of the motor without changing
wiring.
