SINAMICS S120 Braking Resistance

Hello Experts


I have come across a discrepancy in the Specifications of 

DBR Type : 6SL3000-1BE32-5AA0

As Per Manual / CA01 Catalog :

Continuous Power ( Pdb ) = 50kW
Peak Power - 15 Sec in 90 Sec (P15) = 250kW

However as per the Duty Cycle Graph :

Continuous Power = 0.25 of Rated Power = 12.5kW
Peak Power - 15 Sec in 90 Sec (P15) = 1.25 * rated Power = 62.5 kW

Can anyone verify Which is the correct data ?

I have uploaded the relevant Manual Pages for Reference

Thanks

The resistor 6SL3000-1BE32-5AA0 can 50kW all the time, or 250kW for 15s if you make a gap of 75s afterwards

 Does that mean that the Duty Cycle Diagram as given in the manual is Wrong ?

No, Duty cycle ( 90 sec ) states as below

If braking power = 5 x Pdb =  permissible time is 15 sec & afterward off time is 75 sec

If braking power = 4 x Pdb = permissible time is 20 sec & afterward off time is 70 sec.

If braking power = 2 x Pdb = permissible time is 40 sec & afterward off time is 50 sec.
