operation panel and parameter unit (FR-PU04) to the motor speed or machine
speed.

Speed display
<Setting>
To display the machine speed, set in Pr. 37 the machine speed for 60Hz operation.
CAUTION
The motor speed is converted from the output frequency and does not match
the actual speed.
When you want to change the monitor (PU main display) of the operation
panel, refer to Pr. 52 "operation panel display data selection" and
communication parameter n16 "PU main display screen data selection".
Since the operation panel indication is 3 digits, make a setting so that the
monitor value does not exceed "999". If the Pr. 1 value is higher than 60Hz and
Pr. 1 value × Pr. 37 value > 60Hz × 999
(write error) occurs when Pr. 1 or Pr. 37 is written.
REMARKS
When the speed is set in Pr. 37 (Pr. 37
monitor/frequency setting mode.
At this time, setting can be made in the minimum setting (display) increments of 0.01r/min.
Due to the limitations on the resolution of the set frequency, the indication in the second
decimal place may differ from the setting.
Make sure that the running speed setting is correct.
Otherwise, the motor might run at extremely high speed, damaging the
machine.
