14.28 Applying the Rotary Axis Configuration Parameter
Precautions
(1) After turning ON the power, resetting the NC, emergency stop, or issuing the arbitrary axis exchange control (G140/
G141/G142) or mixed control I/II command, the state will be that rotary axis configuration parameter is not applied. There-
fore, issue the function targeted for the combination after applying the rotary axis configuration parameter.
(2) Rotary axis configuration parameter is switched when "Rotary axis configuration parameter switch request signal (R2615/
bit8)" turns ON (0 -> 1). If you want to switch again after the configuration switch, set the configuration No. for rotary axis
configuration parameter and turn OFF and ON the "Rotary axis configuration parameter switch request signal".
(3) If the axes set to the designated rotary axis configuration parameter do not exist all in the part system at the time of
switching the rotary axis configuration, the operation error (M01 0186) occurs.
(4) If "Rotary axis configuration switch request signal" is turned ON during the function targeted for the combination, the oper-
ation error (M01 0187) occurs.
(5) Regardless of the setting for "#1450 5axis_Spec/bit2" (Application of rotary axis configuration parameters), "Configuration
No. of rotary axis configuration parameter (R656/lower 8 bits)" will be output. However, "Rotary axis configuration param-
eter switch completion signal (R656/bit8)" will be turned ON only when the setting of "#1450 5axis_Spec/bit2" is "1" (PLC
signal method).
(6) When using the tool center point control, also be careful with the following points:
(a) If the arbitrary axis exchange command (G140) is issued during the tool center point control, the program error (P942)
occurs.
(b) If any axis of the part system where tool center point control is active has become an exchange target axis, the oper-
ation error (M01 1101) occurs. This alarm is canceled by reset.
(c) After the arbitrary axis exchange, the rotary axis prefiltering is disabled.
(d) If you use the graphic check to draw the tool center point control command issued after the arbitrary axis exchange,
the graphic check draws a machining path from which the arbitrary axis exchange command is ignored.
(7) When using the inclined surface machining/simple inclined surface machining command, also be careful with the follow-
ing points:
(a) When the reset of modal retention (#1151 rstint = 0) is performed during the inclined surface machining or simple
inclined surface machining mode, the rotary axis configuration parameters applied at the time of reset continue to be
applied after the reset.
(b) When the NC reset is performed with the setting (#1210 RstGmd/bitF=1) which retains the inclined surface machining
modal during simple inclined surface control (G176), the rotary axis configuration parameters applied at the time of re-
set continue to be applied after the reset.
(c) For the graphic check drawn the inclined surface machining command/simple inclined surface machining command
after the axis exchange, the drawing will be that the machining path which axis exchange command is ignored.
(d) Use the 3-dimensional manual feed when you take out the tool used for inclined surface machining command/simple
inclined surface machining command.
Usage example: Perform 3-dimensional manual feed (tool center point rotation) using the axes exchanged from 1st part
system to 2nd part system (X1, Y1, Z1, and B1)
2nd part system
Z1
Y1
X1
