To display the machine speed, set in Pr. 37 the machine speed for 60Hz operation.
Note:1. The motor speed is converted into the output frequency and does not match
the actual speed.
2. To change the parameter unit (FR-PU04) monitor (PU main display), refer to
Pr. 52.
3. Only the PU monitor display uses the unit set in this parameter. Set the other
speed-related parameters (e.g. Pr. 1) in the frequency unit.
4. Due to the restrictions of the resolution of the set frequency, the displayed
value may be different from the setting for the second decimal place.
CAUTION
Make sure that the running speed setting is correct.
Otherwise, the motor might run at extremely high speed, damaging the
machine.
