Tab. 6-34: Setting range of parameter 37
Machine speed conversion formula: Pr. 37 × frequency/60Hz
Hz is displayed in 0.01Hz increments and machine speed is in 0.001.
NOTES Under V/F control, the output frequency of the inverter is displayed in terms of synchronous
speed, and therefore, displayed value = actual speed + motor slip. The display changes to the
actual speed (estimated value calculated based on the motor slip) when advanced magnetic flux
vector control was selected or slip compensation was made valid.
Refer to Pr. 52 when you want to change the PU main monitor (PU main display).
Since the panel display of the operation panel is 4 digits in length, the monitor value of more than
"9999" is displayed "----".
When the machine speed is displayed on the FR-PU04/FR-PU07, do not change the speed by using
an up/down key in the state where the set speed exceeding 65535 is displayed. The set speed may
become arbitrary value.
While the machine speed is displayed on the monitor, values of other parameters related to speed
(Pr. 1, etc.) are in frequency increments. Set other parameters (Pr. 1, etc) related to speed in incre-
ments of frequency.
Due to the limitations on the resolution of the set frequency, the indication in the second decimal
place may differ from the setting.
When frequency or set frequency is monitored from network option card except for FR-A7NC
Ekit-SC-E, frequency is displayed for monitor description regardless of Pr. 37 setting.

CAUTION:
Make sure that the running speed setting is correct. Otherwise, the motor might run at extremely
high speed, damaging the machine.
