13.8.4 Relation with Other Functions

Allowing/denying gear changes when related functions are operating
The following table lists the operation that occurs when a command to change gears is output while related functions are
operating. The operations in the following table also apply when the spindle-mode servo motor control is operating.
Gear change commands should only be output when the function is in the "Change" status as listed in the operation column in
the following table. Although gear changes can be made during dwell (Revolution-based designation), the feed per revolution,
and the constant surface speed control do not output gear change commands during these scenarios as doing so may affect
processing.

Remarks
change commands were output during the Z-phase transit opera-
tion.
Changing gears while the spindle is operating changes the speed of
the spindle, which prevents workpieces from being cut correctly. Do
not perform cut processing during gear changes (spindle gear se-
lection input signals 1 and 2 (GI1 and GI2) do not match with the
spindle gear selection output signals 1 and 2 (GO1 and GO2)).
Changing gears while the spindle is operating could cause the ac-
tual spindle speed display on the screen to change in accordance
with the gear ratio.

tion/deceleration.
when the gear change commands were output during C-axis mode.
