6.10 Monitor display and monitor output signals
6.10.1 Speed display and speed setting (Pr. 37)
You can output RPM rates, speeds and throughput volumes based on the output frequency to
the displays of the operation panels, FR-PU04 and FR-PU07 parameter units or to the AM
output.
The above parameters can be set when Pr. 160 = 0.
The maximum value of the setting range differs according to the Pr. 1 "Maximum frequency"
(Parameter 18 "High speed maximum frequency") and it can be calculated from the following
formula:
Note that the maximum setting value of Pr. 37 is 9998 if the result of the above formula exceeds
9998.
To display the machine speed set Pr. 37 to the reference value for the speed to be shown at
60Hz. For example, if the speed is 55m/min at 60Hz set Pr. 37 to "55". The display will then show
"55" when the motor frequency is 60Hz.
