Example 2
When both the "forward run JOG start signal" and "reverse run JOG start signal" are turned ON simultaneously for one axis,
the "forward run JOG start signal" is given priority. In this case, the "reverse run JOG start signal" is validated when the BUSY
signal of Simple Motion module is turned OFF. If the forward run JOG operation is stopped due to stop by a stop signal or axis
error, the reverse run JOG operation will not be executed even if the "reverse run JOG start signal" turns ON.
