Basic Theory
SST and SST1 control the spindle speed and the Z axis feed position synchronously.
During execution of CYCLE 84, the switches of the feed rate override and the cycle stop
(feed hold) are deactivated.

Parameters Meanings Remarks
DTB=0.7 Pause 0.7 s during final tapping to
thread depth (discontinuous cutting)
SDAC=5 Spindle state after cycle is M5 Enter values
3/4→M3/M4
PIT=2（Range of val-
ues:0.001~2000 mm）
Right hand thread with 2mm pitch Evaluate value→left
hand thread
POSS=5
Spindle stops at 5º （unit: º）
SST=5 Tapping thread spindle speed is
5 r/min
SST1=5 Retraction spindle speed is
5 r/ min
Direction is opposite
to SST SST1=0
→speed is same as
SST
