Example
More than nine axes are to be controlled with FC19 using a special application. We
recommend that you proceed as follows:
• Reserve free key on MCP
• Evaluate this key as a flipflop
• Evaluate the flipflop output as pos. and neg. edge
• For pos. edge write one set of axis numbers in the axis table (DB10) and switch on LED
via this key.
• For neg. edge write one set of axis numbers in the axis table (DB10) and switch on LED
via this key.
