Detailed description
2.12 Block descriptions
For FC 19, the maximum possible number of axis selections can also be restricted.
This upper limit is set for the
1. Machine Control Panel in DB10, ... DBW30 (symbolic Name: MCP1MaxAxis) or for the
2. Machine Control Panel in DB10, ... DBW54 (symbolic Name: MCP2MaxAxis) for the
respective MSTT.
The default setting is 0, corresponding to the maximum number of configured axes. The axis
numbers and the limit can also be adapted dynamically. Afterwards, a new axis must be
selected on FC 19. Axis numbers may not be switched over while the axes are traversing the
relevant direction keys.
The compatibility mode is preset with axis numbers 1 to 9 for both MCPs and the restriction
for the configured number of axes.
