7-2 Message Communications Programming

7-2-1 Inverter Fault Processing

The message communications programming example given here reads and stores the fault data using explicit messages for fault outputs from the Inverter. If the Inverter has a fault, the remote I/O input’s Fault Bit (word m bit 0) will turn ON. Be sure to turn OFF the Run Command Bits (word n bits 0 and 1). In this program example, the fault code is stored in DM 0200.

If commands are interrupted by faults, store the completion code in the DM Area and re-execute the command. When a fault occurs, check the contents of the fault and take countermeasures referring to information provided in the SYSDRIVE 3G3FV High-functionGeneral-purpose Inverter User’s Manual (I516).
