154 Using High-Speed Outputs
The PTOX CS (Controlled Stop) bit is used to stop an executing PTO
instruction, in the run portion of the profile, by immediately starting the
decel phase. Once set, the decel phase completes without an error or fault
condition.
If the CS bit is set during the accel phase, the accel phase completes and
the PTO immediately enters the decel phase.
