→
When connecting multiple motors in parallel to the output of 
a variable frequency drive, the motor currents are
 
added
 
geometrically
 
– separated by effective and reactive current 
components.
When you select a variable frequency drive, make sure that it 
can supply the total resulting current. It may be necessary to 
install motor chokes or sine filters between the variable 
frequency drive and the motor in order to dampen and 
compensate for deviating current values.
