Note:
 You can apply the V1000 communication option board to the GA500, provided that you must purchase and assemble the
communication option board cover (option). The assembling procedure is described in the instruction manual that comes with
the option board cover.
 Set DIP switch S2 to ON to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
