(2) When JOG direction flag is changed to reverse run JOG command
during forward run JOG operation
When " JOG. 4 JOG direction flag" is changed to the reverse run JOG command
during forward run JOG operation, forward run JOG operation is continued. In
this case, the reverse run JOG command is made valid when the JOG start
signal turns ON after the BUSY signal of the QD70 turned OFF. However, when
forward run JOG operation is stopped by the axis stop signal or stopped due to
an axis error, reverse run JOG operation is not performed if " JOG. 4 JOG
direction flag" is changed to the reverse run JOG command.
