TE7: Continue machining at the contour (retrace support) - 840D sl only

19.3 Startup

19.3 Startup
19.3.1

Activation

Before commissioning the technological function, ensure that the corresponding compile cycle
has been loaded and activated (see also Section "TE01: Installation and activation of loadable
compile cycles (Page 549)").
Activation
The "Continue machining - Retrace support" technology function is activated via the following
machine data:
MD60900+i $MN_CC_ACTIVE_IN_CHAN_RESU[0], bit 0 = 1
Note
The "Continue machining - Retrace support" technological function is available only in the
1st channel of NC.
19.3.2

Definition of the RESU working plane

Machining continuation/reverse travel is possible only for part program blocks that contain
traversing blocks in the configured RESU working plane.
The RESU working plane is defined with the following machine data:
MD62580 $MC_RESU_WORKING_PLANE
Value
1
2
3
19.3.3

Memory configuration: Block memory

The technological function requires additional data in the NCK-internal block memory. The
values must be increased for the following memory configuring channel-specific machine data:
● MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS += 4 (number of block elements for
compile cycles)
● MD28100 $MN_MM_NUM_CC_BLOCK_USER_MEM += 20 (size of block memory for
compile cycles (DRAM) in KB)
706
Meaning
The RESU working plane is formed by the 1st and 2nd Geometry axes of the 1st channel (for
G17).
The RESU working plane is formed by the 1st and 3rd Geometry axes of the 1st channel (for
G18).
The RESU working plane is formed by the 2nd and 3rd Geometry axes of the 1st channel (for
G19).
