Gear Ratio
Changing the absolute gear ratio causes the slave axes to jump to a new position specified by the new gear ratio. With servo motor systems the slave jumps immediately. With stepper systems, if the new slave position is within 4,000 steps, it jumps to the new position. Otherwise, the slave axis waits until the commanded slave position moves to within 4,000 steps and then jumps to the new position. The slave axis then resumes following the master axis according to the gear ratio.

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. |
