4. Motion Control Instruction 5. Introduction to Mask As the figure shows below, one position capture is completed after the trigger times for rising edge of the TriggerInput bit reach Mask value when Windowonly=1, “Execute” turns Off -> On, and the actual position of terminal actuator is within the Window zone; The trigger of rising edge of the TriggerInput bit is invalid when the actual position of terminal actuator is out of the Window zone.
When the actual position of the terminal actuator exceeds LastPos and no position is captured, the “Error” bit of CapturePosition instruction is on; position capture could be done again by triggering of the rising edge of “TriggerInput” bit after “Execute” turns Off -> On again. When Windowonly=0 and “Execute” turns Off -> On, one position capture is completed after the trigger times for rising edge of the TriggerInput bit reach Mask value (Mask=0 or 1, one position capture is completed after the triggering of the rising edge of the TriggerInput bit occurs once). 4-98 DVP-MC operating manual
