ATV71 Load Sharing: : Needs a whitepaper on Load Sharing

Published date: 24 September 2018

Issue:
 ATV71 Load Sharing: Needs a whitepaper on Load Sharing

Product Line:
 ATV71

Environment:
Load sharing

 
Cause:
 
We don't have more than the training module concerning the load sharing, this document has been created from the development file where there are the same synoptic. However I attach the load sharing training module.

. When LBA is equal to NO, the load balance function is not activated
. When LBA is equal to YES, the load balance function is activated, and the correction using torque reference allows to reduce or increase the speed of the motor depending on the load.
. The load balance speed correction could be adjusted by parameter :
. LBF : adjust the time constant (low filter) of the torque reference
. LBC : define the nominal speed load balance correction
. LBC1 : define the low speed for torque decreasing function speed reference
. LBC2 : define the high speed for torque decreasing function speed reference
. LBC3 : define the torque offset for torque correction

. The load balance speed correction is equal at : LoadBalanceSpeedCor = K1*K2 (see the diagram in training module)
Reminder
This function is used only in SVC vector control.
Default value :
LBC = 0Hz
LBF = 100ms
LBC1= 0Hz
LBC2= 0Hz
LBC3= 0%
