6-2. Output Signal

The signals output from the interpolation box are A and B phase signals in the form of a
voltage differential output complying with EIA-422. Please confirm that the minimum input
phase difference of the controller or counter connected to this probe is smaller than 200 ns
prior to use.

6-2-1. Output Signal Phase Difference

Phases A and B output from the interpolation box are generated approximately every 20 µs. The
phase A and B signals output from the interpolation box change depending on the speed of
movement. The minimum phase difference between phases A and B is 200 ns.
