User-defined function code 1: Monitored data of function code specified by o48
(e.g., speed monitor M06, M09, M79. etc.)
Access to function code (number):
Value specified by "Request for access to function codes" instance
Access to function code (group):
Value specified by "Request for access to function codes" instance
Access to function code (read data): Value read from the specified function code when requested
read/write is normal
Access to function code (error code): Error code displayed (see Table 7.3) when requested read/write is
abnormal
Others:
Same as for input instance 101.

02
No function code (in writing)
Attempted to write to a nonexistent function code.
03
Function code not allowed to change
Attempted to write to a read-only function code.
06
Not allowed to change in running
Attempted to write to a function code not allowed to
change when the inverter is running.
07
Not allowed to change with X terminal
being ON
Attempted to write to a function code not allowed to
change when X terminal is ON.
08
Data entry range error
Attempted to write data out of the range.
0F

21
No function code (in reading)
Attempted to read from a nonexistent function code.
(3) Examples for writing and reading to/from function codes
Normal writing and reading
This example shows communication data for writing to function code F03 (=0403h) to change the data from
factory default 60.0 Hz (=0258h) to 300.0 Hz (=0BB8h) and then reading from F03. (The following data is
expressed in hexadecimal.)
Select the inverter's function code F03.

Reading/writing error
This example shows communication data that returns an error code since writing and reading to/from
nonexistent function code F99 (=0463h) is attempted.
Select the inverter's function code F99.
