[VX-2000 Control input insulation]
Because the VX-2000's control input uses photocouplers, it can be insulated by performing settings to be
externally powered.
This setting disconnects both CTRL IN 1 – 8 Common terminal and CTRL IN 9 – 16 Common terminal from the
VX-2000's internal GND terminal, changing them to external power supply terminals. (Refer to
p. 8-17 for the
setting procedure.)
