FDEP=5 Reach first drilling hole depth. Z axis
coordinate is -5 (absolute coordinate
value)
FDPR=5 From the reference plane, drill
downwards 5mm
DAM=90 Decrement is 90
DTB=0.7 Pause 0.7 s during final tapping of
thread depth (discontinuous cutting)
DTS=0.5 Stops at the start position for 0.5 s
(for VARI=1,removal active)
FRF=1 Original effective feed rate remains
(range:0.001~1) unchanged
VARI=0 Interruption in drilling is active
AXN=3 AXN is tool axis,under appointed
G17 use Z axis
MDEP=5 Minimal drilling depth 5 mm
VRT=1.4 Interruption in drilling, the retraction
value of the quill is 1.4 mm
DTD=0.6 Pauses at the position of final drilling
depth for 0.6 s
DIS1=1.6 When reinserting a quill, you can
program a distance limit of 1.6 mm

DTB <0: Unit is r
DTS <0: Unit is r
Feed rate modulus
VARI=1 retraction of active
quill back to reference plane
The value of AXN decides
which axis to use
This parameter activates only
when DAM <0
VRT=0 → retraction value is
1mm
VRT>0 → retraction value is
appointed value
DTD <0:unit is r, DTD
=0:same as DTB

handbook
DAM parameter
① DAM≠0, the first drilling operation (FDPR) cannot exceed the drilling depth. As of the
second drilling operation, the drilling is acquired from the last depth operation (drilling
depth=last drilling depth-DAM). The calculated drilling must be ≤ DAM. If the calculated
drilling is =DAM, as of the next feed, the DAM value will be the feed depth until the end of
the feed. If the last remaining depth is <DAM, then drilling is performed automatically until
the required depth is reached.
② DAM=0,drilling depth each time is same as the 1st drilling depth (FDPR),
In case the residual depth <2xFDPR,the last 2 cutting depth are half of the residual depth.
Example:40 mm deep hole as an example, with DAM=2 mm and DAM=0 mm feed
