Power Dissipation

DOK-INDRV*-HMV-*******-PR01-EN-P
The power dissipation of a drive system radiated to the control cabinet is
calculated from the sum of the power dissipation of the supply unit, the
power dissipation of the mains connecting unit, the power dissipation of
each drive controller, and the power dissipation of additional units (e.g.
DC bus resistor unit or DC bus capacitor unit).
The power dissipation of a supply unit is composed of
• power dissipation of the control voltage supply unit
• current-related power dissipation of rectifier (HMV01.1E) resp. inverter
(HMV01.1R), wiring and mains contactor
• power dissipation of braking resistor unit (HMV01.1E) resp.
emergency braking resistor (HMV01.1R)
