Direct LOGIC MODBUS Ladder Programming (cont.)
Rung 16 loads a decimal value of 600 into drive parameter 9-26. The BIN instruction
converts BCD/HEX to decimal. This tells the drive to run at 60.0Hz.
Rung 17 sets the motion of the drive to forward by loading a value of 0 into
parameter 9-28. V2021 is the 18th V-memory register in the block of 20 that is
being written to in the WX instruction in Rung 5.
Rung 18 sets the motion of the drive to reverse by loading a value of 1 into parameter
9-28. V2021 is the 18th V-memory register in the block of 20 that is being written
to in the WX instruction in Rung 5.
