For example, when
=100Hz,
=90.0%, and motor rated
frequency=50.00Hz:
If the detected load value during motor upward
running is 30.0%, the limited
frequency=150Hz(90.0%*50.00Hz/30.0%), the
calculated limited frequency is higher than
. If P91.08=1, the set frequency P00.03 is
used for running. If P91.08=2, the constant
power speed limit frequency does not work, and
the set frequency is used for running.
If the detected load value during motor upward
running is 60.0%, the limited frequency
=75Hz(90.0%*50.00Hz/60.0%), the heavy load
speed limit function works. The upward max.
output frequency is limited to 75Hz. If P91.08=1,
the frequency 75Hz is used for running. If
P91.08=2, the max. running frequency is 75Hz,
and the set frequency is used for running.
The similar calculation method is applicable to
motor downward running, only replacing
with
Note: During open/closed loop switchover (there
is difference in load detection value), adjust
, and the heavy load speed
limit frequency cannot be lower than the heavy
load speed limit detection frequency
