Mitsubishi Electric FR-D720-0.2K-G Instruction Manual page 136

NOTE
 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 "----". To display or set the speed of 10000r/min or more on the operation panel for the motor with the maximum
rotation speed of 10000r/min or more, change the item for speed display to the frequency.
 When the machine speed is displayed on the 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.
 When the machine speed display is selected, monitored items and speed setting are displayed in machine speed
increments, but the 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.
Make sure that the running speed setting is correct.
Otherwise, the motor might run at extremely high speed, damaging the machine.
