The direction of rotation is determined by IS "Set direction of rotation counterclockwise" or IS "Set direction of rotation
clockwise" (DB380x.DBX2002.7 or .6).
The oscillation movement and the two times t1 and t2 (for clockwise and counterclockwise rotation) must be simulated on
the PLC.
The IS "Gear changed" (DB380x.DBX2000.3) informs the NC that the new gear stage (IS "Actual gear stage"
(DB380x.DBX2000.0 to .2)) applies and oscillation mode is exited. The actual gear stage should correspond to the set gear
stage. Oscillation mode is also ended if the IS "oscillation speed" (DB380x.DBX2002.5) is still set. The last programmed
spindle speed (S function) and spindle rotation (M3, M4 or M5) are active again.
After termination of oscillation mode the spindle returns to control mode.
All gear specific limit values (min./max. speed etc.) correspond to the set values of the actual gear stage and are deactivated
when the spindle stops.
If the spindle has been changed over to oscillation mode, IS "Change gear" (DB390x.DBX2000.3) is set, part program
processing is stopped. A new block is not executed. If oscillation mode is terminated using the IS "Gear switched"
(DB380x.DBX2000.3), the execution of the part program is continued. A new block is executed.
Block change following oscillation mode:
● The acceleration is defined by MD35410 SPIND_OSCILL_ACCEL (acceleration during oscillation).
● If the IS "oscillation speed" (DB380x.DBX2002.5) is reset, the oscillation stops. However, the spindle
in
oscillation mode.
● The IS "Gear changed" should always be used for terminating gear stage change.
● The IS "Reset" (DB3000.DBX0000.7) does
terminate oscillation mode.
● If an indirect measuring system is used, synchronization is lost. The spindle is re-synchronized the next time the zero
mark is crossed.
Reset during gear stage change
The spindle cannot be stopped via IS "Reset" (DB3000.DBX0000.7) or IS "NC Stop" (DB3200.DBX0007.3) if the spindle is in
oscillation mode for gear stage change and the IS "Gear changed" (DB380x.DBX2000.3) 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 d
istance-to-go / Spindle Reset" (DB380x.DBX0002.2).
