„ Ladder Logic Programming
Ladder logic programs are designed mainly for sequence control. The setting parameters and
monitor parameters used as interfaces with the Motion Modules are directly written to and
read by the ladder logic programs to perform motion control.
Special operations can be programmed and combined as user functions.
For details, refer to Chapter 6 Parameters and descriptions on parameters given for each
Motion Module.
„ Motion Programming
The motion programs that have been created perform motion control using a special motion
language. Up to 32 programs can be created, and these can also be executed in parallel.
The system performs command completion checks and other overhead processes.
The use of the special motion language enables complex operations to be easily pro-
grammed. The special motion commands shown in the following table are provided as stan-
dard in the MP9
†† Series.
