[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
for the
setting procedure.)
