Question

What is the method of confirming abnormalities of the number of output pulse (omission of the number of pulse) in the incremental rotary encoder?

Answer

It is possible to judge it by counting the number of pulse signals from phase Z signal to the next phase Z signal if there is phase Z output.

Moreover, it is possible to judge it by counting the number of pulse signals when the axis is made one rotation after a standard position somewhere is made to be understood in the axis and the chassis if there is no phase Z output.
