4.13 Braking Resistor HLR01
HLR01.1N‑xxxx‑Nxxx‑A‑007‑NNNN braking resistors convert generated ki‐
netic energy into thermal energy. For this purpose, the line covers a wide
range of continuous power and energy absorption capacity.
Type Usage
HLR01.1A Type of construction A (version for device mounting): To
be mounted to drive controllers of the Rexroth IndraDrive
C product range. For this purpose, the drive controllers
must be equipped with a brake chopper.
HLR01.1N Type of construction N (version for free assembly): For
free assembly in the installation, operated by drive control‐
ler of the Rexroth IndraDrive C product range. For this pur‐
pose, the drive controllers must be equipped with a brake
chopper.

Cement-coated, wire-wound, tube-type fixed resistors; screwed on side
walls; perforated cover; connections in terminal box with PG gland
● Steel-grid fixed resistor IP 20 type B
Fixed resistor in steel-grid design; connection depending on type
● Steel-grid fixed Resistor IP 20 type C
Fixed resistor in steel-grid design; connection depending on type
