148 Using High-Speed Outputs• Set (1) - Configures the PTO instruction to produce an S-Curveprofile.• Cleared (0) - Configures the PTO instruction to produce a Trapezoidprofile.PTOX Idle Status (IS)Sub-ElementDescriptionIS - Idle StatusAddress Data Format Range Type User ProgramAccessPTOX:0/ bit 0 or 1 status read onlyISThe PTOX IS (Idle Status) is controlled by the PTO sub-system. It can beused in the control program by an input instruction. The PTO sub-systemmust be in an idle state whenever any PTO operation needs to start.The IS bit operates as follows:• Set (1) - PTO sub-system is in an idle state. The idle state is definedas the PTO is not running and no errors are present.• Cleared (0) - PTO sub-system is not in an idle state (it is running)PTOX Error Detected (ED)Sub-ElementDescriptionAddress Data Format Range Type User ProgramAccessED - Error Detected Status PTOX:0/ED bit 0 or 1 status read onlyThe PTOX ED (Error Detected Status) bit is controlled by the PTOsub-system. It can be used by an input instruction on any rung within thecontrol program to detect when the PTO instruction is in an error state. Ifan error state is detected, the specific error is identified in the error coderegister (PTOX:0.ER). The ED bit operates as follows:• Set (1) - Whenever a PTO instruction is in an error state• Cleared (0) - Whenever a PTO instruction is not in an error statePublication 1766-RM001A-EN-P - October 2008
