General Information

Standard and Reinforced Design
HLR01.1
DOK-INDRV*-ADDCOMP****-PR02-EN-P
For the drive controllers HCS02 and HCS03 there are external standard
braking resistors HLR01.1N-xxxx-Nxxx-A-007-NNNN available. The drive
controller HCS monitors the external braking resistor by means of the
firmware which calculates a thermal image of the current braking power.
When the limit values for the thermal image are exceeded, the converter
switches off with error "F8820 braking resistor overload" to protect the
baking resistor from overload.
Note: Choose drive controllers HCS03 in design -NNBN (braking
transistor integrated) or drive controllers HCS02 with type
current W0054 or W0070 so that you can operate braking
resistors HLR01.1.
We distinguish two designs of braking resistors HLR01.1:
• The standard design is intended for assembly above the drive
controller HCS03.1E.
• The reinforced design is not intended for assembly at the drive
controller HCS03.1E.
For regenerative braking at higher power, occurring for example in drives
with large centrifugal masses (e.g. centrifuges), long braking processes
(e.g. in crane lifting gears), reinforced braking resistors should be
connected to the converters with integrated brake chopper.
Damage to the drive controller HCS by braking
resistor HLR01 incorrectly selected and
parameterized!
When selecting the braking resistor HLR01, take the
⇒
CAUTION
allowed minimum resistance value into account. For
the minimum resistance value please see the
electrical data of the drive controllers HCS02 and
HCS03.
⇒ At the drive controllers
parameterize the performance data of the selected
braking resistor in parameter "P-0-0858, Data of
external braking resistor".
⇒ Activate the selected braking resistor by setting
bit 8 = 1 in parameter "P-0-0860, Control word of
power section".
