Appendix 5.2 Connection example of D75P2 and MR-J2/J2S- A
(Differential driver (Open collector)) *
*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 The distance between the controller and amplifier is indicated.
The distance must be within 2m with the open collector.
*5 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.
*6 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 AD75C20SNJ2 cable (for differential driver) can be used for the connection between the D75P2 and MR-J2/J2S-
A. (Refer to section "2.2 List of configuration devices.")
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.
