3.2.6 Absolute position (ABS) detection wiring
This section explains the wiring needed when a Mitsubishi MR-H/MR-J2/MR-J2-Super servo
motor is connected and the absolute position detection function (ABS) is used.
To detect the absolute position, the parameter Nos. 50, 51 and 52 must be set.
When general purpose I/O are used (FX
2N
-10GM, FX
2N
-20GM)
The figure below shows an example of wiring when the general purpose I/O points built in the
positioning unit are used.
In the example below, the parameters are set as follows.
PARA 50: ABS interface. Set to "1": Valid
PARA 51: ABS input head No. Set to "0": X00
PARA 52: ABS control output head No. Set to "0": Y00
When extension blocks are connected (FX
2N
-20GM)
The example below shows the wiring performed when the absolute position is detected using
extension blocks connected to CON5 of the FX
2N
-20GM.
PARA 50: Set to "1"
PARA 51: Set to "10": X10
PARA 52: Set to "10": Y10
