Page 11: Terms And Abbreviations
Introduction to the manual 11 Terms and abbreviations Term Description Brake chopper Conducts the surplus energy from the intermediate circuit of the drive to the brake resistor when necessary. The chopper operates when the DC link voltage exceeds a certain maximum limit. The voltage rise is typically caused by deceleration (braking) of a high inertia motor. -
Page 13: Operation Principle And Hardware Description
This chapter introduces the operation principle and construction of the brake unit. Product overview The ACS880-604LC is a liquid-cooled resistor brake unit available in the ACS880 multidrive modules product range. The design presented in this manual has an NBRW-669C liquid-cooled brake chopper module with two brake resistors. The chopper module has a liquid-cooled heat sink which transfers most of the generated heat into the coolant. - Page 14 Typically, a drive system is equipped with a brake chopper or brake choppers if • high capacity braking is needed and the drive cannot be equipped with a regenerative supply unit • a backup for the regenerative supply unit is needed. Standard resistors are available from ABB for each brake chopper module.

Page 65: Internal Cooling Circuit
Internal cooling circuit 65 Internal cooling circuit Contents of this chapter The cooling system of a liquid-cooled drive consists of two circuits: the internal cooling circuit and the external cooling circuit. The internal cooling circuit covers the heat-generating electrical components of the drive and transfers the heat to the cooling unit. In the cooling unit, the heat is transferred to the external cooling circuit which is usually part of a larger external cooling system. - Page 66 66 Internal cooling circuit Supply modules Inverter modules To/From cooling unit Air-to-liquid heat exchanger Heat sink Inlet valve Inlet-side drain valve Outlet valve Outlet-side drain valve The coolant used with ACS880 liquid-cooled drive systems is Antifrogen® L 25% or 50% water mixture.
