    inverter,s stall functions

    inverter stall prevention selection during running.
    inverter stall prevention function selection during operation.
    0 : non effective .
    1 : effective deceleration time 1.
    2 : effective deceleration time 2.

    how to make inverter

    when inverter setting 1 or 2 enabled is selected deceleration is started
    if the current of the stall prevention level during operation continues
    for more than 100 mrs . the motor is accelerated back to inverter reference
    frequency again the current falls bellow this level.

    inverter stall prevention level during running .
    it is effective when l3-05 is set to be 1 or 2. it is set in unit of % with rated
    current taken as 100 %.
    it is effective when l3-05 is set tube 1 or 2 . normally it is no need to be changed.
    when the motor,s power is less than the inverter,s capacity or stall occurs to the motor
    when operated with factory setting, please decrease the value. this value is in unit of %
    with motor,s rated current taken as 100% .

    how to work inverter in solar system

    speed agree detection level.
    effective when arbitrary frequency ( speed ) agrees 1 is set for multi function output.
    it is the setting when multi function output frequency agree arbitrary frequency agree and
    frequency detection signal is output…
    odor speed is detected at flux vector control.

    inverter speed agree detection width.
    it is the setting when multi function output frequency agree arbitrary frequency agree signal is output.

    inverter speed agree detection level (+/-).
    effective when arbitrary frequency (speed) agree 2 is set for multi function output.

    speed agree detection width (+/-).
    effective when frequency (speed) agree arbitrary (speed) agree 2 are set for multi function output.

    inverter operation when frequency reference is missing.
    frequency detection operation ,0: stop (operation follows the frequency reference,) .
    1: operation at 80% speed continues, (at 80% of speed before the frequency reference was lost).
    frequency reference is lost: frequency reference dropped over 90% in 400 mrs.

    number of auto restart attempts.
    set the number of auto restart attempts, automatically restarts after a fault and
    conducts a speed search from the run auto frequency (speed).
    the inverter might be damaged when using the fault restart function too frequency.
    when fault restart function used please do use circuit breaker. the peripheral machine
    will stop operation once the inverter is at faultbif the program is designed with
    the so called fault restart is to automatically restart when fault occurs in side of the
    during operation.
    the fault restart function is applicable for the following fault.for the other fault,the
    restart function is not effective, the inverter will take protection action immediately.

    oc (over current        pf(input pha loss)
    ol1 (motor             gf (ground fault)
    overloaded)
    lf (output pha loss)   ol2 (inv overloaded)
    puf(dc bus fuse       rf (braking resistor
    open)                 overheated)
    ol3(over torque det 1) ov (over voltage)
    rr (dyn brk transistr) ol4 (over torque det 2)
    uv1 (dc bus
    under volt)

    the counter for fault restart attempts will be reset attempts will be reset to be 0 under
    the following circumstances.when operation is normal for 10 minutes after a fault restart is performed.
    when the fault reset input is received after the protection operation has been activated and the fault
    confirmed. when the power is turned off and then on again . when one of the multi function outputs
    (h2-01,h2-02, or h2-03) is set to 1e (restart enabled ) , the output will be on while the fault restart
    function is in progress.

    inverter auto restart operation selection.

    inverter sets whether a fault contact output is activated during fault restart. 0: not output (fault contact
    is not activated) 1:output (fault contact is activated).

    1. Hmm it looks like your blog ate my first comment (it was super long) so I guess I’ll just sum it up what I wrote and say, I’m thoroughly enjoying your blog. I too am an aspiring blog blogger but I’m still new to everything. Do you have any recommendations for newbie blog writers? I’d definitely appreciate it.
