10. Spindle Functions
(14) The phase offset request signal will be ignored when the phase shift calculation request signal
is ON.
(15) The phase error of the basic spindle and synchronous spindle saved in the NC is valid only
when the phase shift calculation signal is ON and for the combination of the basic spindle
selection (H_) and synchronous spindle (D_) commanded with the rotation synchronization
command (no R address).
For example, if the basic spindle and synchronous spindle phase error is saved as "G114.1
H1 D-2 ;", the saved phase error will be valid only when the phase offset request signal is ON
and "G114.1 H1 D_2 R ∗∗∗ ;" is commanded. If "G114.1 H2 D-1 R ∗∗∗ ;" is commanded in this
case, the phase shift amount will not be calculated correctly.
(16) The phase error of the basic spindle and synchronous spindle saved in the NC is retained until
the spindle synchronization phase shift calculation, in other words, until the rotation
synchronous control command completes with the phase shift calculation request signal is
ON.
(17) Synchronous tapping can not be used during spindle synchronous mode.
(18) When the spindle synchronous control commands are being issued with the PLC I/F method
(#1300 ext36/bit7 OFF), a program error (P610) will occur if the spindle synchronous control is
commanded with G114.1/G113.
