Master Encoder - Slave Axis Gearing (beginner's question)

Hello

In the documentation of this vi there is a sentance:

"Note: The use of the term "rotations" here assumes that the encoders being used have the same number of counts per revolution."

And what about situation when encoder 'A' (master) has 'X' encoder counts per revolution and this value varies from the resolution of the encoder 'B' (slave).
These two stepper motors have the same resoultion.
If I set the gear master parameter (in the slave axis B) to the axis A everything will work okey - I mean the slave axis will follow the master axis position at specified ratio.
I use 7344 Motion Controler and NI-Motion 6.0 (May 2003 Edition).

Thank you for your help.
Best regards
Peter

Modo,

What you have describes sounds correct. What you have to make sure of in this situation is that the differences in counts per revolution are taken account for in your parameters.
