Feed axis fault: Actual traversing direction opposite to selected/displayed

What does Axis opposite direction mean?

The actual movement direction of the axis is opposite to the direction selected in operation or displayed on the PPU screen.

• Incorrect setting of machine data MD32100 (axis traversing direction)
• Incorrect setting of machine data MD32110 (encoder position feedback polarity)

Click steps to track your progress.

1. 1

   Check the setting of machine data MD32100 for axis traversing direction. Change it to -1 if the default value is 1 and the direction is opposite.

2. 2

   Check the setting of machine data MD32110 for encoder position feedback polarity. Change it to -1 if the default value is 1 and the direction is opposite.

3. 3

   Perform a test movement in JOG mode to confirm the axis now moves in the correct direction.
