(2) Basic operation example
The switch status of STOA is input to SDI2A+ of MR-J3-D05, and then it will be input to STO1 and STO2
of the servo amplifier via SDO1A and SDO2A of MR-J3-D05.
The switch status of STOB is input to SDI2B+ of MR-J3-D05, and then it will be input to STO1 and STO2
of the servo amplifier via SDO1B and SDO2B of MR-J3-D05.
