Calculation with regard to reduction of resulting power dissipation
CZM01.3
When braking the drive, the rotary energy present in the mechanics is fed
back to the DC bus of the DKC in the form of regenerated energy. It can
• Be reduced to dissipated heat via the braking resistor integrated into
the DKC or an auxiliary braking resistor can additionally be built in
- or -
• It can be stored as energy in the DKC with connected auxiliary
capacitance module and then re-used for acceleration procedures.
This reduces the heat in the control cabinet and lowers energy
consumption.
For a successful
implementation and an avoidance of unnecessary heat
loss in the control cabinet, it applies:
CZM,ZWDKC,ZWAnlageR, WWW +≤
W R,Anlage : required regenerative power of the system
W
ZW : storable energy of the DC bus capacitors
