Line modules 
Convert the three-phase supply into a DC voltage for the DC link. 
●  Smart line modules 
The smart line modules generate a non-stabilized DC link voltage and are capable of 
regenerative feedback. 
●  Active line modules 
The active line modules generate a stabilized DC link voltage and are capable of 
regenerative feedback. 
●  Basic Line Modules 
Basic Line Modules generate an unregulated DC link voltage and are not capable of 
regenerative feedback. 
Motor modules 
●  Convert energy from the DC link for the connected motors with variable voltage and 
variable frequency.
