P91.16=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 P00.03.
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 P91.16
with P91.17.
Note: During open/closed loop switchover (there is
difference in load detection value), adjust P91.16
and P91.17, and the heavy load speed limit
frequency cannot be lower than the heavy load
speed limit detection frequency P91.14.
P91.16, P91.17 setting range: 30.0%
–120.0% (of
the motor rated power)
