inverter auto restart stall functions


inverter,s stall functions

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

when 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 the reference
frequency again the current falls bellow this level.

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% .

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

speed agree detection width.
it is the setting when multifunction output frequency agree arbitrary frequency agree signal is output.

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

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

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 defore 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
inverter 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(overcurrent        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(overtorque det 1) ov(overvoltage)
rr(dyn brk transistr) ol4(overtorque det 2)
uv1(dc bus
undervolt)

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.

auto restart operation selection.

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).
