Motion Axis Gear Instruction

3 posts in this topic

I needed some help understanding and using the Motion Axis Gear instruction in a CompactLogix system. As I understand it that instruction will synchronize a slave servo axis to an axis I designate as master. My question is when in my code do I use the instruction? Do I need to home each axis individually then run the MAG instruction? After running it, can I then only issue one MAM instruction to the master axis and the slave will follow? Thanks.

you need to home each axis before you can run. if you gear one axis with another, then slave will follow whatever master does.

While it is normal to home axes before telling them to move, it is not absolutely necessary for a gearing operation, since actual position of either axis is irrelevant to the gearing operation. You use the MAG instruction when you want slave axis velocity to follow master axis velocity at a specified ratio. It is probably more common for the master axis to be moving continuously (e.g. MAJ) and / or driven externally.
