11.2 MULTIPLE M COMMANDS IN A SINGLE BLOCK
In general, only one M code can be specified in a block. However, up to three M codes can be specified at once in a block by setting bit 7 (M3B) of parameter No.3404 to 1. Up to three M codes specified in a block are simultaneously output to the machine. This means that compared with the conventional method of a single M command in a single block, a shorter cycle time can be realized in machining.

If a duplicate axis name is specified in the parameter, operation is enabled only for the axis specified first.
2 CONTROLLED AXES
NOTE In two path control, axis information displayed on the
tools?
2 CONTROLLED AXES
The least command increment is either metric or inch depending on the machine tool. Set metric or inch to the parameter INM (No.100＃0).
2 CONTROLLED AXES
Limitations ·Default axis name
When a default axis name (1 to 8) is used, operation in the MEM mode and MDI mode is disabled. ·Duplicate axis names
When this parameter is set to 0 or a character other than the valid characters is specified, an axis name from 1 to 8 is assigned by default.
In two path control, the basic three axis names are fixed to X, Y, and Z for either path, but the name of an additional axis can be selected from A, B, C, U, V, and W by parameter 1020. Duplicate axis names cannot be used in the same path, but the same axis name can be used in different paths.
