(2) When both the "Forward run JOG start signal" and "Reverse run JOG start
signal" are turned ON simultaneously for one axis
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 LD75 BUSY signal is turned OFF. If the forward run JOG operation is stopped due to stop
or axis error by a stop signal, the reverse run JOG operation will not be executed even if the "Reverse run JOG
start signal" turns ON.
