6.22 Reference Position Retract
6.22.1 Outline
This function returns immediately to a set reference position when the Reference position retract signal is input. This
function is used to return to a set position for changing the tool.
6.22.2 Detailed Description
Reference position return is executed when this signal is turned ON. At the rising edge of the signal, the program is
automatically reset (reset & rewind) and then reference position return is executed.
During the automatic or MDI operation, the operation is interrupted and stopped by the reset, and reference position
return is executed.
If this signal is input during execution of a tap cycle in the automatic or MDI operation modes, the "Tap retract possible"
signal will be output by the reset interruption, and the return operation will be the tap retract operation. The tap retract is
completed at the initial point, and after that the reference position return will be carried out.
(1) If there are two or more axes, set the return order with parameter "#2019 revnum".
(2) When the reference position is reached, the corresponding "Reference position reached" signal will be output.
(3) This signal must be held until the "Reference position reached" signal is output. If it is turned OFF midway, the
return operation will be interrupted and stop. If the signal is input again, the operation will restart from execution of
resetting.
(4) The reference position return speed is handled in the same manner as the normal reference position return speed.
(5) In this function, an axis returns to the reference position set by the Reference position selection code 1 and 2 signal.
(6) Even if the return signal is input during the thread cutting cycle, it will be invalid. However, if the return signal is
executed in a block other than the thread cutting block, the return operation will be executed.
(7) The return signal is invalid if the coordinate system is not established. An alarm "M01 Ref point retract invalid" will
occur when the return signal is input.
