4. REFERENCE POSITION ESTABLISHMENT
215
For details about this signal, see 3.1, “Feed Axis and Direction Selection
Signal”. Only notes on use of reference position return are given, here.
NOTE
The direction of reference position return is set for each axis
by parameter ZMI (No. 1006#5). If the tool is fed opposite
to the preset direction in manual reference position return,
while the deceleration signal is “0”, the tool feeds until the
signal returns to “1”. The reference position return is then
performed automatically in the predetermined direction.

NOTE
When reference position return is selected, an axis who has
already completed referencing movement along that axis is
disabled while the reference position return selection signal
(ZRN) is “1”. To perform movement again, ZRN must be set
“0”, and the feed axis and direction selection signal must be
reset to “0” and then returned to “1” again.
