Appendix 5 Connection examples with servo amplifiers manufactured by MITSUBISHI
Electric Coporation
For connection to a servo amplifier, dedicated cables are available. For wiring of the
dedicated cables, refer to the manual of each dedicated cable.
Appendix 5.1 Connection example of D75P2 and MR-H A
(Differential driver (Open collector)) *

In the following diagram, connection for absolute position restoration has not been
made. When making the connection for absolute position restoration, refer to the
following page.
*1 Assignment of the pin numbers of the connector of the D75P2 is the same for axis 1 and axis 2.
*2 The upper limit (FLS) and lower limit (RLS) of the D75P2 are used for zero point return retry function. Set these inside the limit
switches for the servo.
*3 Limit switch for servo (stopping).
*4 For details of connection, refer to the specification manual of the servo amplifier MR-H.
*5 The distance between the controller and amplifier is indicated. The distance must be within 2m with the open collector.
*6 Use “Logic selection for pulse output to the drive unit” specified in detailed parameter 1 to match the logic (positive or negative
logic) between the D75P2 and the servo amplifier. The initial setting of D75P2 is a positive logic.
*7 There is no need to wire the in-position signal. (It is output as in-position signal (RX(n+1)4, RX(n+4)4) but it is not used for internal
processes of the D75P2.)
REMARK
The AD75C20SNH cable (for differential driver) can be used for the connection between the D75P2 and MR-H A.
