FANUC Series 16/18/160/180-Model C Machining Center Operators Manual

15. COMPENSATION FUNCTION
B–62764EN/01
PROGRAMMING
326
WARNING
1 When cutter compensation C mode is set and all–axis machine lock is applied, the G53
command does not perform positioning along the axes to which machine lock is applied. The
vector, however, is preserved. When CCN (bit 2 of parameter No. 5003) is set to 0, the vector
is canceled. (Note that even if the FS15 type is used, the vector is canceled when each–axis
machine lock is applied.)
Example 1: When CCN (bit 2 of parameter No. 5003) = 0,
type A is used, and all–axis machine lock is applied
Example 2: When CCN (bit 2 of parameter No. 5003) = 1
and all–axis machine lock is applied [FS15 type]
Example 3: When CCN (bit 2 of parameter No. 5003) = 1
and specified–axis machine lock is applied [FS15 type]
2 When G53 is specified for a compensation axis in cutter compensation mode, the vectors along
the other axes are also canceled. (This also applies when CCN (bit 2 of parameter No.5003)
is set to 1. When the FS15 type is used, only the vector along a specified axis is canceled.
Note that the FS15 type cancellation differs from the actual FS15 specification in this point.)
Example: When CCN (bit 2 of parameter No.5003)=1[FS 15 type]
