7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
375
NOTE
1 If an axis for which a reference position is established and
an axis for which no reference position is established are
simultaneously specified with G28 when bit 2 (ALZ) of
parameter No. 7055 is set to 1, G28 is executed after turning
off the AI advanced preview control mode, regardless of the
setting of bit 3 (AZR) of parameter No. 7054.
2 If the serial spindle is switched to the Cs contour control
mode then G00 is specified for the Cs contour control axis
without performing a reference position return operation
even once during AI advanced preview control when bit 1
(NRF) of parameter No. 3700 is set to 0, a P/S alarm (No.
090) is issued, regardless of the setting of bit 2 (ALZ) of
parameter No. 7055.
ADP Single direction positioning in the AI advanced preview control mode is
executed:
0 : In the normal mode.
1 : In the AI advanced preview control mode.
