Rexroth IndraDrive Control Circuits for the Mains Connection 11-5
DOK-INDRV*-SYSTEM*****-PR02-EN-P
Note: Observe the allowed switching capacity of the Bb contact of
the CSB01.1-FU control sections.
Compared to other control sections, only the CSB01.1-FU
control section has a Bb contact with allowed switching voltage
of AC250V.
Note: During the time required until the internal supply voltages are
built up and the firmware is actively working in the drive
controller, the Bb contact at the control section of the drive
controller is open.
Take these times into account for the design of the mains
connection.
Control Circuits HCS02 with DC Bus Resistor Unit HLB01.1C
You should use this variant when
• only motors with permanent magnet excitation are connected.
• motors with permanent magnet excitation and asynchronous motors
(induction machines) are connected.
Due to the DC bus short circuit, motors with permanent magnet excitation
can be shutdown with deceleration even if the electronic system of the
drive is disturbed. (see also section Deceleration in the Case of E-Stop or
Mains Failure)
WARNING
Personal injury caused by uncontrolled axis
motion!
The DC bus short circuit protects machines in the case of
drive errors. By itself it cannot assume the function of
personal protection. In the case of errors in the drive or
supply unit, uncontrolled drive motion can occur even
when the DC bus short circuit has been activated.
Asynchronous machines do not brake when the DC bus
has been short-circuited. Personal injury can occur
according to the machine design.

Provide additional monitors and protective devices on
the installation side.
