Page 143 from 180 

Example:

 Measurement results of VC deployment on the drive with flywheel. 

 

 

Kinetic backup of converter at power supply voltage 

failure on the motor with flywheel.

 

Dynamic deceleration at different inertias of the drive.

 

In  many  industrial  applications  of  the  drives  with  frequency  converters  it  is  required  to  stop  the 
drive in the shortest time. This significantly reduces the cycle time of repeated working cycles and 
has a direct impact on production productivity. In addition, if it is a drive, where moment of inertia 
and loading ratios are variable, fixed time of ramp-down setting can be problem. Then is necessary 
to  apply  dynamic  deceleration  mode.  For  example,  spin-driers,  mills,  blenders,  where  inertia 
depends on the amount of processed material. 

8.7  Flux braking 

Several  braking  modes  can  be  used  in  frequency  converters.  Mainly  it  is  the  use  of  a  braking 
module  and  a braking  resistor.  However,  there  are drives,  where  braking  conditions  occur  partly 
and not often. For example, if it is needed to stop the pump in 10 seconds, but during the ramp-
down an "Overvoltage" fault occurs, it is not necessary to use the braking module. If for example 
13  or  15  second  long  ramp-down  ends  without  a  fault,  the  amount  of  generated  energy  can  be 
decreased by using the 

Flux braking function.

 

 
To activate the function - flux braking use this parameter: 
Parameter ID: 775 
SETTINGS 

–

> CONTROL AND REGULATION -> FLUX BRAKING -> Flux braking (FB) 

 

 

It  works  as  follows:  the  converter  starts  to  increase  the  motor 
voltage  after  exceeding  the  "FB  working  voltage",  and  excitation 
(flux)  is  increased.  This  causes  that  a  part  of  the  energy  is  not 
flowing  from  the  motor  to  the  converter,  but  it  is  transformed  to 
heat in the motor coil.  Increasing the flux braking rate is possible 
by using the parameter "Flux braking gain [777]". 

 
Parameter ID: 776
