3 Basic System Operation
3.4.3 Motion Programming
3-22
• The ladder logic programs that are generated for motion program control are created automatically
using the external input signals that are allocated on the Group Definition Window. These ladder
logic programs can also be used as is. It is recommended, however, that they be used as templates
to be optimized (changed) to suit individual system requirement.
• When a ladder logic programs used for motion program control is created by automatic generation,
up to eight motion programs can be called simultaneously from the ladder logic program. In other
words, when automatic generation is used, a maximum of eight groups will be controlled.
