Notes
The inverter output voltage can be raised to
improve the motor torque at low speeds.
If the inverter trips and displays
the RUN switch is operated, the low frequency
voltage boost should be adjusted upwards in
0.1% increments until the motor starts without
tripping. Note that excessive boost can also
cause tripping or motor overheating due to
the motor current being too high. (Adjustable
while the motor is running.)
The boost may also be set using the
automatic
boost feature, set by P19.
Note that P01 cannot be adjusted manually
when automatic boost is enabled.
Short ramp–up times will result in high motor
currents being drawn during start–up which
can cause the inverter to trip (F00).
Short ramp–down times will result in voltage
regeneration from the stored mechanical
energy in the motor which may cause the
inverter to trip (F00).
0 V = 0 Hz, 10 V = max. frequency P08.
0 mA = 0 Hz, 20 mA = max. frequency P08.
4 mA = 0 Hz, 20 mA = max. frequency P08.
The frequency of the inverter can be
adjusted upwards or downwards using the
keys. However, when the inverter is
stopped and restarted, it will always run to the
frequency stored in parameter P09.
As 003 but the rate of change of the frequency
is fixed (i.e. does not increase after a few
seconds). The feature may be useful in some
automated control functions.
As 003 but parameter P09 is updated (after a
delay of about 3 s) to the new adjusted value. In
this case, when the inverter is stopped and
restarted, it will run to the new frequency stored
in parameter P09.
As 004 but incorporates the P09 update feature
of 005.
