H5-12
(043D)
Mbus Run Command
Method Sel
Sets the input method for the Run command when b1-02 = 2 [Run Comm. Sel 1 = Modbus] or b1-
16 = 2 [Run Comm. Sel 2 = Modbus].
0
(0, 1)
0 : F/ST R/ST
The drive uses bit 0 in command data 0001H of the Modbus 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/ST F/R
The drive uses bit 0 in command data 0001H of the Modbus 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)).

Mbus Speed Filter over
Comms
Sets the filter time constant used when monitoring motor speed during Modbus communications
or with a communication option.
0 ms
(0 - 100 ms)
Sets the filter time constant when you monitor the output frequency or motor speed during Modbus
communications or use of the communication option.
These are the Modbus registers:
• 003EH (Output Frequency)
• 003FH (Output Frequency)
• 0044H (U1-05: Motor Speed)
• 00ACH (U1-05: Motor Speed)
• 00ADH (U1-05: Motor Speed)

2 : Reload Now
Note:
• The setting value automatically returns to H5-20 = 1 after you enable Modbus communications parameter changes.
• The setting values of these parameters are enabled:
–H5-01 [Mbus Address]
–H5-02 [Mbus BaudRate]
–H5-03 [Mbus Parity]
–H5-06 [Mbus Tx Wait Time]
