DirectLOGIC MODBUS Ladder Programming (cont.)
Rung 7 is used to set bit C55 if the AC drive has an error. Rung 8 will reset bit C55.
Rung 9 is used to set bit C51 if the AC drive has a specific error. In this example
C51 will be set if the AC drive has an overcurrent error. Rung 10 will reset bit C51.
Rung 11 loads a value of 1 into drive parameter 9-27. This is the signal to run.
V2020 is the 17th V-memory register in the block of 20 that is being written to in
the WX instruction in Rung 5.
Rung 12 loads a value of 0 into drive parameter 9-27. This is the signal to stop.
V2020 is the 17th V-memory register in the block of 20 that is being written to in
the WX instruction in Rung 5.
