Setting Notes
(Default)
00.0 – The inverter output voltage can be raised to improve the motor torque at
30.0 low speeds.
If the inverter trips and displays F00 when 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.
FREQUENCY
Note that P01 cannot be adjusted manually when automatic boost is
enabled.
(00.0)
00.0 – Short ramp up times will result in high motor currents being drawn
400 during start–up which can cause the inverter to trip (F00).
(10.0)
00.0 – Short ramp down times will result in voltage regeneration from the
400 stored mechanical energy in the motor which may cause the inverter to
trip (F00).
(10.0)
000 0 V = 0 Hz, 10 V = max. frequency P08.
001 0 mA = 0 Hz, 20 mA = max. frequency P08.
002 4 mA = 0 Hz, 20 mA = max. frequency P08.
003 The frequency of the inverter can be adjusted upwards or downwards
using the
restarted, it will always run to the frequency stored in parameter P09.
004 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.
005 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.
006 As 004 but incorporates the P09 update feature of 005.
007 0 V = min. frequency P07, 10 V = max. frequency P08.
008 0 mA = min. frequency P07, 20 mA = max. frequency P08.
009 4 mA = min. frequency P07, 20 mA = max. frequency P08.
