Mitsubishi Electronics MR-J2S- A manual

15. ABSOLUTE POSITION DETECTION SYSTEM

Note 1: For the dog type home position return. Need not be connected for the data set type home position return.

2:If the servo motor provided with the zero point signal is started, the A1SD75(AD75) will output the deviation counter clear signal. Therefore, do not connect the clear signal of the MR-J2-A to the A1SD75(AD75) but connect it to the output module of the programmable controller.

3:This circuit is provided for your reference.

4:The electromagnetic brake output should be controlled via a relay connected to the programmable controller output.

5:Use the differential line driver system for pulse input. Do not use the open collector system.

6:To reinforce noise suppression, connect LG and pulse output COM.
