Spindle (S1)
20.2 Spindle modes
Block change
If the spindle has been changed over to oscillation mode, IS "Change gear" (V390x 2000.3)
is set, part program processing is stopped. A new block is not executed. If oscillation mode is
terminated using the IS "Gear switched" (V380x 2000.3), the execution of the part program is
continued. A new block is executed.

Reset during gear stage change
The spindle cannot be stopped via IS "Reset" (V3000 0000.7) or IS "NC Stop" (V3200
0007.3) if the spindle is in oscillation mode for gear stage change and the IS "Gear changed"
(V380x 2000.3) is not yet available.
In this case, alarm 10640 "Stop not possible during gear change" is displayed if reset is
selected. After changing the gear stages, the reset request is performed and the alarm
cleared, if this is still present at the interface.
Note
Option for aborting: Set IS "Delete distance-to-go / Spindle Reset" (V380x 0002.2).
