#3129 cax_spec
bit5 : Retention of coordinate system setting offset at switchover to C axis mode
[M8]
Select whether to retain the offset for the coordinate system setting(G92/G50) or local coordinate system set-
ting (G52) when the control is switched to C axis mode.
0: Not retain the offset for coordinate system setting
1: Retain the offset for coordinate system setting
[C80]
Not used.
bit4: Gain switchover for all the axes within the part system when C axis is selected
0: The gains of servo axes except C axis are not switched when C axis is selected.
1: The gains of servo axes except C axis are switched when C axis is selected.
#2203(PGN1) SV003 --> #2249(PGN1sp) SV049
#2204(PGN2) SV004 --> #2250(PGN2sp) SV050
#2257(SHGC) SV057 --> #2258(SHGCsp) SV058
bit3: Mode selection at reset when the program command method is selected
0: Spindle mode
1: The mode at reset is retained.
This parameter is enabled when the program command method is selected (#3129 cax_spec/bit0=1).
bit2: Mode selection at Power ON when the program command method is selected
0: Spindle mode
1: C axis mode
This parameter is enabled when the program command method is selected (#3129 cax_spec/bit0=1).
bit1: Coordinate system setting when the deceleration stop type (no zero point return) is selected
Select the C axis coordinate system setting method when the deceleration stop type (no zero point return) is
selected.
0: Establish the coordinates of the deceleration stop position by using the Z-phase position as the coordi-
nate zero point.
1: The deceleration stop position is used as the coordinate zero point.
bit0: Spindle position control changeover method
Select the method of changing the mode between C axis and spindle.
0: PLC signal method
1: Program command method
#3130 syn_spec
bit2: Error compensation between reference and synchronized spindles
0: Error compensation is performed.
1: Error compensation is not performed.
*Set this parameter for the synchronized spindle.
bit1: Phase alignment method selection
0: Phase alignment method type 1 (step alignment method)
1: Phase alignment method type 2 (multi-step acceleration/deceleration method)
*Set this parameter for the synchronized spindle.
bit0: Tool spindle synchronization II (hobbing) automatic compensation selection
0: No compensation.
1: Compensate hobbing axis delay (advance) with workpiece axis.
#3131 tap_spec
Not used. Set to "0000".
