2.8 H: Terminal Function Selection
348 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
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)).

• 003FH (Output Frequency)
• 0044H (U1-05: Motor Speed)
• 00ACH (U1-05: Motor Speed)
• 00ADH (U1-05: Motor Speed)
