The following data can always be read. They are automatically refreshed every time
the END instruction is executed.
(1) Operation monitor
The following data devices are always read-enabled (write-disabled) to allow you to
monitor the output frequency, output current and output voltage of the inverter. Note
the setting units.
(2) Error history (error codes and error definitions)
The inverter stores the error codes of the errors that occurred.
The error codes of up to four errors are stored in the order as shown below and are
