Gearing Settings

Use the Gearing Settings tab to configure the gearing settings for master and slave axes.

You can configure the gearing master, enable or disable gearing, gearing slave or slaves, set the gearing mode, and configure ratio of revolutions of the slave axis or axes per revolution of the master axis.

Note  National Instruments recommends disabling gearing before resetting the position of the master axis or the slave axis. When the position of either the master axis or the slave axis is reset, the reset offset is treated as gearing offset, and the slave axis jumps to the new gear position in one PID period.

Note  If you are running a slave axis move with a stepper axis, it is possible that the slave axis geared velocity exceeds the maximum step rate of the controller. In this case, the controller kills the axis and sets the following error status to true. Refer to the Specifications section of your controller user manual for the maximum step rate of your controller.

NI SoftMotion Considerations

If you are using only one axis with the NI SoftMotion Controller for the Copley Controls CANopen Accelnet or Stepnet drives, this tab is not applicable because there is no other axis to gear to.

If you are using only one axis with the NI SoftMotion Controller for the Copley Controls CANopen Xenus drive, you can use this tab to configure the axis to gear to the ADC on the axis.
