·The read data is a fixed floating-point value, with a same format as the
display on the operation panel of the inverter.
·If a read error occurs, "eXXXX" is returned as an error code. See list
of error codes for details of the error codes.
·Refer to "Note" for the read data format of F5001 (motor poles,
voltage and capacity).
· Output frequency: 50 Hz
