Dear, Here are you sketch with mine how i expect firing angle at the begining when reference start the the error will be 10 v then max firing will happen related to (ALPHA) 0 then it will compare current limit then it will increase (ALPHA) to keep current control. then if we need full speed then max output of voltage need then (ALPHA) again will reach to zero. Hope this correct and aslo an attachments for old drive shown block diagram in simple way. Regards, Attachmentfiring angle and drives.zip (275 Downloads) |
