Braking resistor HLR01
HLR01.1N-xxxx-Nxxx-A-007-NNNN braking resistors convert generated kinetic
energy into thermal energy.
Table 46: DC bus resistor units HLR
Type
HLR01.1N
Types of design:
● Fixed resistor IP 20 Type A
● Steel-grid fixed resistor IP 20 Type B
Basically, all HLR01.1 types can be used that comply with the requirements
on the minimum resistance, the continuous power and peak power, as well as
the regenerative power to be absorbed (see technical data of the component
(chapter "External braking resistor/integrated braking transistor" in the Project
Planning Manual R911386579, ctrlX DRIVE Drive Systems).
Selecting an HLR01 braking resistor:
HLR01.1N-XXXX-NYYY-A-007-NNNN
● XXXX continuous power (e.g., 07K0 = 7 kW)
● YYY resistance value (e.g., 14R0 = 14 ohm)
See documentation "Rexroth IndraDrive, Additional Components and Accesso-
ries, Project Planning Manual, R911306140" for selecting an HLR01 braking
resistor.

Additional components mains filters XNF and power choke XNL
Information on mains filters XNF and mains chokes XNL can be found in Project
Planning Manual R911386579.
In some cases, mains filters HNF01.x and mains chokes HNL01.x are used.
Information on mains filters XNF and mains chokes XNL can be found in Project
Planning Manual R911342564.
