When the NC is reset by pressing the MDI reset key or by the issue of an
external reset signal, reset and rewind signal, or emergency stop, B--axis
control is also reset. The reset signal (ECLRg) can reset only B--axis
control.
A B--axis operation can be executed only when the B--axis can be
controlled by the PMC. For details, refer to the manual supplied by the
machine tool builder.
1. Only a single--motion operation can be specified with G110.
G110 G00 B100. ; OK.............
G110 G28 ; OK..................
G110 G81 B100. R150.0 F100 ; P/S alarm No.5034...
2. A canned cycle (G81 to G86), and other operations containing
multiple motions, cannot be specified with G110.
If an inhibited operation is specified, P/S alarm No.5034 is output.
3. modal information specified with G110 does not affect the subsequent
blocks. In the G110 block, the initial modal value specified at the start
of the operation becomes valid, irrespective of the modal information
specified the previous blocks.

Block (2) instigates cutting feed (G01) at 2.0 mm/rev (G99).
Block (3) instigates rapid traverse (G00).
Block (4) instigates cutting feed (G01) at 1000 mm/min (G98).
4. During tool--nose radius compensation, two or more G110 blocks
cannot be specified in succession. If such blocks are specified in
succession, P/S alarm No. 5041 is output. To specify two or more
G110 blocks in succession for a B--axis operation, register the blocks
as a program with G101, G102, or G103 and G100.
