Type QD75P/QD75D Positioning Module User’s Manual (Hardware) QD75P1, QD75D1 QD75P2, QD75D2 QD75P4, QD75D4 Thank you for buying the Mitsubishi general-purpose programmable logic controller MELSEC-Q Series Prior to use, please read both this manual and detailed manual thoroughly and familiarize yourself with the product.
! SAFETY PRECAUTIONS ! (Always read before starting use) When using this equipment, thoroughly read this manual. Also pay careful attention to safety and handle the module properly. These precautions apply only to this equipment. Refer to the User’s Manual of the CPU module to use for a description of the PLC system safety precautions. These "Safety Precautions" classify the safety precautions into two categories: "DANGER" and "CAUTION".
[WIRING PRECAUTION] DANGER ! Switch all phases of the external power supply off when installing or placing wiring. Not doing so may cause electric shock or damage to the product. CAUTION ! Check the layout of the terminals and then properly route the wires to the module. ! Solder connectors for external device properly. Insufficient soldering may cause malfunction. ! Be careful not to let foreign matter such as sawdust or wire chips get inside the module. These may cause fires, failure or malfunction.

Performance Specifications (1) The performance specifications for the QD75P1, QD75P2 and QD75P4 Item Number of axes Maximum output pulse count Maximum connection distance between servos Applicable wire size Applicable connector Number of I/O occupied points 5 V DC current consumption Flash ROM write count Weight Specification QD75P2 2 axes QD75P1 1 axis QD75P4 4 axes 200 kpulse/s 2m (6.56ft) 0.
3. Handling CAUTION ! Use the PLC in an environment that meets the general specifications contained in CPU module User's Manual to use. Using this PLC in an environment outside the range of the general specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the product. ! When installing the module, securely insert the module fixing tabs into the mounting holes of the base module while pressing the installation lever located at the bottom of the module downward.

5. Wiring DANGER ! Switch all phases of the external power supply off when installing or placing wiring. Not doing so may cause electric shock or damage to the product. 5.1 Wiring Precautions (1) If cables to connect to QD75 absolutely must be positioned near (within 100 mm) the power line, use a general shielded cable. The shield must be grounded on the QD75 side.
Wrap the coated parts with a heat contractile tube. (2) The shielded cable for connecting QD75 can be secured in place. If the shielded cable is not secured, unevenness or movement of the shielded cable or careless pulling on it could result in damage to the QD75 or drive unit or shielded cable or defective cable connections could cause mis-operation of the unit.
5.2 External Interface The internal circuits of interface for connecting external devices to the QD75 are shown by the schematic diagrams in the tables below (for the QD75P1 and QD75D1).

5.3 Wiring of the differential driver common terminal When the differential driver output type (QD75D1/QD75D2/QD75D4) is used, an inter-common potential difference may occur between the differential driver common terminal and the differential receiver common terminal of the drive unit. To eliminate an inter-common potential difference, connect between the differential driver common terminal of the QD75D1/QD75D2/QD75D4 and the differential receiver common terminal of the drive unit.
