12.4.10 Inverter communication error occurrence step [D8153 and D8158]
These devices store the step number in which an inverter communication error has occurred.
1. Detailed contents
D8153 or D8158 stores the step number of the instruction causing an inverter communication error.
D8153 stores the step number in which an error has occurred in communication using communication port
ch1.
D8158 stores the step number in which an error has occurred in communication using communication port
ch2.
When errors that occurred in two or more instructions, D8153 or D8158 holds the step number in which the
error occurred first.
When no error has occurred, D8153 or D8158 stores "-1".
2. Cautions on use
A decimal value without the sign is stored as the step number in D8153 and D8158.
12.4.11 IVBWR instruction error parameter number [D8154 and D8159]
These devices store the parameter number in which an error has occurred when IVBWR instruction error flag
"M8154 or M8159" turns ON.
1. Detailed contents
D8154 or D8159 stores the parameter number which was not written by IVBWR instruction.
D8154 stores the parameter number which was not written in communication using communication port ch1.
D8159 stores the parameter number which was not written in communication using communication port ch2.
When errors that occurred in two or more IVBWR instructions, D8154 or D8159 holds the parameter number
in which the error occurred first.
263
