This dual-axis positioning module specializes in open collector pulse train outputs, providing seamless command control for stepper drives and servo systems. Designed for flexible architecture, it coordinates independent point-to-point (PTP) operations, continuous path trajectories, and multi-axis interpolation directly from the PLC backplane.\u003c\/p\u003e\n\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eBy housing dedicated processing hardware on-board, the \u003cstrong\u003eQD75P2N\u003c\/strong\u003e offloads complex path calculations from the main CPU, ensuring consistent 1.5 ms startup response times. It supports multiple engineering unit systems, including millimeters, inches, degrees, and raw pulses, allowing engineers to program movement parameters directly in native machine units. The module stores up to 600 positioning data points per axis in non-volatile flash ROM, eliminating the requirement for external backup batteries.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square; color: #2d3748; padding-left: 1.5rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cli\u003eDual-axis independent or coordinated motion control.\u003c\/li\u003e\n  \u003cli\u003eSupports 2-axis linear interpolation and 2-axis circular interpolation.\u003c\/li\u003e\n  \u003cli\u003eOpen collector pulse output structure reaching speeds up to 200 kpulse\/s.\u003c\/li\u003e\n  \u003cli\u003eComprehensive motion profiles including PTP, speed control, speed\/position switching, and position\/speed switching.\u003c\/li\u003e\n  \u003cli\u003eTrapezoidal and S-curve acceleration\/deceleration filtering profiles to minimize mechanical resonance.\u003c\/li\u003e\n  \u003cli\u003eBatteryless storage of parameter sets and positioning profiles directly in internal Flash ROM.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square; color: #2d3748; padding-left: 1.5rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cli\u003eX-Y gantry Cartesian coordinate positioning systems.\u003c\/li\u003e\n  \u003cli\u003ePackaging machine indexing and material feed axes.\u003c\/li\u003e\n  \u003cli\u003eRotary table angular positioning using degree-based unit scaling.\u003c\/li\u003e\n  \u003cli\u003eMaterial handling transfer shuttles and automated storage lifters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; width: 100%; margin-bottom: 1.5rem;\"\u003e\n  \u003ctable style=\"border-collapse: collapse; width: 100%; color: #2d3748;\"\u003e\n    \u003cthead\u003e\n      \u003ctr style=\"border-bottom: 2px solid #2b6cb0;\"\u003e\n        \u003cth style=\"text-align: left; padding: 8px; font-weight: bold;\"\u003eSpecification Parameter\u003c\/th\u003e\n        \u003cth style=\"text-align: left; padding: 8px; font-weight: bold;\"\u003eValue \/ Rating\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eManufacturer\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003eMitsubishi Electric\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eModel Reference\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003eQD75P2N\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eSeries\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003eMELSEC Q Series\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eControl Axes\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003e2 Axes\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eOutput Interface Type\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003eOpen Collector Output\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eMaximum Pulse Frequency\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003e200 kpulse\/s\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eInterpolation Modes\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003e2-axis linear, 2-axis circular\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eInternal Current Consumption (5V DC)\u003c\/td\u003e\n        \u003ctd style=\"padding: 8px;\"\u003e0.30 A\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"border-bottom: 1px solid #e2e8f0;\"\u003e\n        \u003ctd style=\"padding: 8px; font-weight: bold;\"\u003eMax.

Parameter structures remain highly backward-compatible; however, project validation within GX Works2 or GX Works3 is required to confirm configuration mapping. If your application demands longer transmission distances or higher pulse rates, consider the differential driver output version (QD75D2N), which extends pulse frequencies up to 4 Mpulse\/s and connection runs up to 10 meters.\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eBecause this module utilizes open collector outputs, the pulse signal quality degrades exponentially with cable length due to parasitic line capacitance. Standard installations must enforce the 2-meter physical limits between the module and the motor driver inputs. Exceeding this distance risks signal distortion, missed pulses, and erratic positioning errors. Additionally, ensure high-voltage motor cabling is separated by a minimum of 100 mm from the 40-pin command signal lines to prevent EMI-induced tracking errors.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eThe open collector output circuits within the module require an external DC power source to energize the optocouplers inside your servo\/stepper drives. Verify that external 5V DC or 24V DC is supplied to the appropriate pin headers on the 40-pin connection layout. If the PLC diagnostics indicate active pulses are generating but the drive receives no commands, verify the presence of this external circuit voltage. We highly recommend using shielded, twisted-pair cables with the screen grounded exclusively on the PLC panel side.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cp style=\"color: #9b2c2c; font-weight: bold; margin: 0 0 0.5rem 0;\"\u003eCRITICAL SYSTEM SAFETY WARNING\u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0; font-size: 0.95rem;\"\u003eIsolate all primary and auxiliary power supplies feeding the PLC rack, servo drives, and field machinery before mounting, removing, or wiring this module.
