0 : FWD/Stop, REV/Stop
The drive uses bit 0 in command data 0001H of the MEMOBUS register in the motor forward Run command (bit 0 =
1) and the stop command (bit 0 = 0). The drive uses bit 1 in the motor reverse Run command (bit 1 = 1) and the stop
command (bit 1 = 0).
1 : Run/Stop, FWD/REV
The drive uses bit 0 in command data 0001H of the MEMOBUS register in the motor Run command (bit 0 = 1) and
the stop command (bit 0 = 0). The drive uses bit 1 in the direction of motor rotation command (Forward run (bit1 = 0)
or Reverse run (bit 1 = 1)).
