When the fixed point toolsetting is executed by hand, X tool offset value sign related to
the tool number is changed, i.e. “+” is changed into “-”and“-”into “+”.
4.4.16 Manual Program Reference Point Return
X, Z zero return (program zero return, machine zero return) operations must be executed at the
same time. If only one axis is being executed, the other maybe bring the unexpected motion.
Press the following keys to execute the program reference point return at any moment after
defining the program reference point.
X program reference point return
Press to return from the current point to X program reference point at the selected
speed.
Z program reference point return
Press to return from the current point to Z program reference point at the selected
speed.
Note:
Cancel separately the tool offset and the system offset in the corresponding axis after
executing the reference point return. After executing X, Z reference point return, the
system returns the state of canceling the tool offset and the system offset, displaying T * 0
(* is the current tool number).
4.4.17 Manual Machine Zero Return (Machine Reference Point Return)
Each machine has a fixed point as a reference point. The accumulative error can be deleted by
returning to the machining starting point after executing the machine zero return each time.
Before machining, firstly execute the machine zero return, and then specify the starting point of
machining, at last, write down its coordinate. For restarting the machine after power off, firstly
execute the machine zero return, and then return to the machining starting point written down to
start programs, which make the actual position accord with the system coordinate caused by
man moving the machine. Cancel the machine zero return when P12 Bit7 is 0.
X machine zero return
Press to move X positively to the machine zero at the selected rapid traverse speed.
