chat avec femmes 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.
power 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% .
power inverter 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.
speed agree detection width.
it is the setting when multi function output frequency agree arbitrary frequency agree signal is output.
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.
power 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.
power inverter stall prevention options during deceleration .
0: non effective .
1: effective .
2: optimum deceleration .
3: effective ,when braking resistor is available .
setting value 0: invalid decelerate according to the setting . over voltage “o v” will occur when deceleration time is too short.
setting value 1: effective stop deceleration when the main circuit voltage is near the voltage level , it decelerates again when the voltage recovers.
setting value 2: optimum deceleration , decide the shortest deceleration time according to the main circuit voltage, it ignores the set deceleration time .
setting value 3: effective braking resistor is available .
when setting 1 enabled is selected , the deceleration time is extended automatically so that a main circuit over voltage does not occur .usually pick placing zero when a braking choice braking resistor , braking resistor unit or braking unit is being used , if placing 1 or 2 is chosen, the braking choice won,t be used and the deceleration time can now not be shortened. l3-04 can not be set to 2 for vector control modes ,
” can be set for the one with below f level” . l3-04 can not be set to be 3 for the control with pg vector . the adjusting method of setting value 3 , and the difference between the setting value 0 and 3 . when the setting is 0 , stall prevention disposal is effective during deceleration when the setting is 3 the over voltage of main circuit is easy to occur , and the automatic deceleration time extension is hard to occur , the motor decelerates according to the decelerating time .
though the actual decelerating time is longer than the set time value in order to set the shortest deceleration time compared to the setting value 0 . obviously the shortest time of deceleration can be effected . when stall prevention function during deceleration is set to be 3 , please do adjust as follows: adjusting sequence .
1, deceleration shall be set according to the braking capacity and mechanical inertia .
2: when the time of 1 is not known , please do trial operation with l3-04 set be 0, after the min deceleration time is abstained , set l3-04 to be .
3: to decrease the value of deceleration time with in the range in which main circuit over voltage won,t occur.
