The configuration is attached. in the system the choke is getting heated up although we have checked the current and voltage are balanced and in range. Choke type no. 6SL3000-0DE21-6AA0 please help. Also Can we introduce breaking resistance in the system if yes can any one give some type no. or neccassary info regarding the same. regards simatic manager Attachment Present system.pdf (147 Downloads)

Sine wave mode of the infeed module causes the line reactor to generally do more work than square wave mode. Can you look at incoming power and identify if the line is being affected by commutation?
