*1 Assignment of the pin numbers of the connector of the A1SD75/AD75 is the same for axes 1 to 3.
*2 The upper limit (FLS) and lower limit (RLS) of the A1SD75/AD75 are used for the 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 A1SD75/AD75 and the servo amplifier. The initial setting of A1SD75/AD75 is a
positive logic.
*6 There is no need to wire the in-position signal. (It is output as " Md.39 External input/output signal" but it is not
used for internal processes of the AD75.)
REMARK
The AD75C20SC cable (for differential driver) can be used for the connection between the A1SD75/AD75 and MR-
C A. (Refer to section 2.2 "List of configuration devices.")
