CN3_0 ~ CN3_2
The 3 pins on CN3 of Mitsubishi servo driver work as COM port, allowing the user
to read and set configuration from/to servo motor via special software from
Mitsubishi. For making things easier, the COM port pins are directed to the CN232
connector of terminal board. By switching JP8~JP9, the users can select which
servo motor among these 3 to communicate with. The pins are dentally explained
as below:

Note1: At speed-control mode, MO2 can be used as feedback signal of PISO-VS600,
therefore parameter 17 of Mitsubishi driver must be set to 0000 when user use the
PISO-VS600 motion card , so that the Servo-motor speed will be output by MO2
(will be connected directly to PISO-VS600analog input).
