Inverter-specific error list (predefined error field)
You can read out the inverter-specific error list using the following objects:
● OV index 1003 hex
● Inverter parameter p8611
It includes the alarms and faults present in the inverter in the CANopen alarm number range
8700-8799.
The errors are listed in the order in which they occur using an error code and additional,
device-specific information.
As soon as a fault is acknowledged or an alarm is resolved, they are deleted from the
inverter-specific error list.
You acknowledge all of the active inverter errors by setting subindex 0 in the OV index 1003
to 0 or setting p8611[0] = 0.
