NOTE
When tool length offset is applied to multiple axes, all
specified axes involved in reference position return are
subject to cancellation.
When tool length offset cancellation is specified at the same time, tool
length offset vector cancellation is performed as indicated below.
Command Specified axis Common to type A/B/C
G49G28P_;
Tool length offset
axis
Canceled upon movement to an
intermediate position being per-
formed
Other than tool
length offset axis
Canceled upon movement to an
intermediate position being per-
formed
Tool length offset vectors, canceled by specifying G53, G28, or G30 in
tool length offset mode, are restored as described below.
(1) When OFH (bit 2 of parameter No. 5001) = 0
Type EVO (bit 6 of pa-
rameter No. 5001)

1 Block to be buffered next
A/B
0 Block containing an H command
or G43/44 command
C
Ignored Block containing an H command
Block containing a
G43P_/G44P_ command
(2)When OFH (bit 2 of parameter No. 5001) = 1
In a mode other than tool length offset mode

rameter No. 5001)
