Brief description
The functionality of relative gearing is provided by the synchronous axis technology object.
The change of the leading axis position setpoint is multiplied by a specified gear ratio and
passed on to the following axis as change in the position setpoint.
The relative gearing couples a following axis to a leading axis as if the axes were connected
via a mechanical transmission.
Leading axis (driven axis)
Following axis
Relative position relationship
The following axis is synchronized to the leading axis by means of the Motion Control
instruction "MC_GearIn", which represents the mechanical transmission in this case. An
active synchronous operation is overridden by motion jobs on the following axis.
