Setting is enabled
when Pr. 30 = "1".
<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 you set the speed in Pr. 37, the speed is monitored in the monitor frequency
setting mode.
At this time, setting can be made in the minimum setting increments of 0.01r/min.
Due to the restrictions 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.
