11. PROGRAM COMMAND
B–63523EN–1/03
1338
WARNING
When switching inch input (G20) to metric input (G21) and
vice versa, the tool compensation value must be re–set
according to the least input increment.
However, when bit 0 (OIM) of parameter 5006 is 1, tool
compensation values are automatically converted and
need not be re–set.
NOTE
1 When the least input increment and the least command
increment systems are different, the maximum error is half
of the least command increment. This error is not
accumulated.
2 Reference position return is performed at a low speed for
the first G28 command after the inch input is switched to the
metric input or vice versa.
3 The inch and metric input can also be switched using
parameter (No. 0000#2).
