Faults, Minor Faults, Alarms, And Error Codes Listed By Decimal Value For Use; With Bacnet/Modbus - YASKAWA HV600 Technical Reference

6.4 Faults, Minor Faults, Alarms, and Error Codes Listed by Decimal Value for Use with BACnet/Modbus
6.4 Faults, Minor Faults, Alarms, and Error Codes Listed by
Decimal Value for Use with BACnet/Modbus
Table 6.3 shows the list of faults by decimal number.
Table 6.4 shows the list of minor faults and alarms by decimal number. Minor fault and alarm decimal numbers are
read in Modbus register 007F.
The display codes are in decimal order. Search the tables for the decimal code, and identify its causes and possible
solutions.
Drive Faults thrown by the HV600 drive will stop the bypass from running the drive but will not stop it from running
in Bypass Mode.
System Faults will stop the drive and also stop it from running in Bypass Mode.
Note:
The number in parentheses adjacent to the code in the table identifies the fault code or minor fault code (hex. number) that was read during
MEMOBUS/Modbus communications.
