C21 Speed Command Unit
C21 specifies units for setting the speed.
Data for C21 and the specified units are as follows.
Data for C21 Speed command unit
0 r/min
1 m/min
2 Hz
3 mm/s
Changing C21 data converts previously specified function code data into a newly specified unit for
display. It also modifies the setting range automatically.
Changing the C21 data requires modifying the data of some function codes. For details,
refer to section 2.2.

As shown in the above equations, changing the data of any of function codes P01, F03, and
L31 automatically modifies the inverter's speed settings specified in r/min or m/min.
C22 Analog Input Type
C22 selects the analog input type of analog multistep speed command.C22 is valid when F01 is set
to 3.
 For details, refer to function code F01.
