During the inverter decelerat ion, the load inertia may cause the actual motor speed drop rate l ower than

t he output frequency drop rate, and thereby the motor generates electricity and feeds it back to the inverter,

caus ing the i nverter bus voltage going up and even bus over-voltage breakdown which t hen can cause

i nverter tripping if no provis ion i s made.

Over-voltage stall protection function is to detect t he bus voltage and compare it with the sta ll over-

voltage point defined by F5.05 (relative to t he standa rd bus voltage) . If i t exceeds the over-voltage stall

point, inverter output frequency s top going down, and when the next bus voltage detected is lower than

t he over-vol tage stal l point, t he inverter continues to decelerate, as shown by followi ng figure:

Fig.6-22 O ver-voltage Stall Funct ion

W hen inve rter is runni ng, the actual climbing ra te of motor speed is lowe r than cl imbing rate of out put

frequency because load is too big. If you don't ta ke any action, it will cause over current faul t in

acceleration then inverter will t rip.

Over-current stal l protect ion function is t o de tect output current and compare it wit h the current limit

defined by F5.06. If it exceeds the c urrent limit, output frequency drop down according to F5.07. When it

s how tha t output current is lower tha n l imit current, inverter wil l remain norma l operation.

It is mai nly applied to the cases that bi g inver ter drives small motor, requiring to corre ctly set up this

funct ion to protect the mot or.

If the inst ant power-down drop rate is set to be 0, the instant power-down res tart function is invalid.

Instant power-down frequency drop poi nt: it i s indicting when the bus voltage, after the power net work

is down and drops to the instant power-down frequency drop point, the invert er sta rts to decreas e the

opera ti on frequency based on the insta nt power-down frequency drop rate, enabli ng the mot or to genera te

Response delay: means the interval time from the end of data receive to transmitt ing response data to

upper l evel machine. If re spons e delay t ime i s s mal le r than system operation ti me, response delay time

s hould be system operation time. If response del ay ti me is l onger than system operati on time, inverter can

not t ransmit data to upper level machine unt il res ponse delay time reached.

When this parameter is set to be 0.0s, thi s function is invalid.

When this functi on is valid, if the interval t ime be tween two communic ations excee ds communication

has 25 pie ces of alarm information and protec ti on func ti ons in t otal. Once the fault occurs,

the protecti on functi on starts, the inverter stops input ti ng, t he fault rel ay contact poi nt is a ctivated, and the

faul t code wil l be di splayed on the display panel of the invert er. Before seeking services , the subscri ber

may conduct the self-check according to the prompt gi ven in thi s section, analyze the fault caus es , a nd fi nd

out the s oluti ons. If t he faul t bel ongs to the causes described in t he broken line box, pl ease s eek t he s ervice

by contacting the inverter agent or directly conta cting our corporation.

Common Faults and the Faul t Diagnosis

The following faults may probabl y occur during t he usi ng of t he inverter, please refer to the methods

des cribed bel ow to perform the faul t analys is.

1. No Electricity Display

1) Chec k wit h mult imeter i f the i nput power supply of the inverter is consist ent with its rate d vol tage.

If the re is somet hing wrong with the power s upply, pleas e chec k and remove it.

2) Chec k i f the three-phase rectifying bridge is intact . If t he rectifying bridge has been exploded,pl ease

seek technical service.

3) Chec k i f the CHARGE indicator is on. If the indica tor is off, t he faul t wi ll be on the recti fying bri dge

or the buffering res ist ance. If the indicat or is on, then the fault may probably lies in the switch on/off part,

pleas e seek for help.

2. The air Sw it ch Trips off After Power-on

1) Chec k i f the earthing or short circuit occurs bet ween the i nput power s uppli es and remove t he problem.

2) Chec k i f the rectifying bridge has been broken down. If so, seek for the servi ce.

3. The Mot or Does not R un After the Inverter S tarts to Run

1) Chec k i f there is equa li zing t hree-phase input bet ween U, V and W. If yes, the motor circuit or itsel f

may be damaged, or t he motor stops turning for mechani cal reason. Please remove it .

2)If there is input but the t hree phases are not equalizing, the i nverter drive board or the output modul e

may be damaged. P leas e seek for the service.

3) If t here i s no out put volt age, the dri ve board or output modul e may be damaged. Please seek for t he

servi ce.

4. W hen the Power-on Inverter Displays Normall y, t he Air Swi tch Trips off After t he Opera ti on.

1) Chec k i f the short circuit occurs between t he output modules. If ye s, please seek t he service.

2) Chec k i f the short circuit or e art hing occurs bet ween the mot or lea d wires. If yes, please remove it .

3) If t he tripping occurs only occasi onally and the dist ance between the motor and the inverter is bi g,

the n the adding of a n out put AC reac tor shall be considered.
