NOTE
 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 slip compensation was 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 as "----".
 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 increments 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.
CAUTION
Make sure that the running speed setting is correct.
Otherwise, the motor might run at extremely high speed, damaging the machine.
