MDrive/MForce – Electronic gearing program sample
This short program shows how to configure an MDrivePlus2 unit to be used in the following mode. The step and directions inputs may be sourced from a programmable controller, dedicated stepper motor controller or even another MDrivePlus2 unit with S7 and S8 configured for step / direction outputs. The CR motion variable allows this axis to perfom electonic gearing by setting up the ratio from 0.001 to 2.00. Important: S7 and S8 are TTL only levels, with a maximum input of 5 VDC.
