9.3.3 Circuits HCS02 and HCS03 with DC Bus Resistor Unit HLB01.1C or
HLB01.1D
Application
Use this variant, when
only motors with permanent magnet excitation are connected
motors with permanent magnet excitation and asynchronous motors (in‐
duction machines) are connected
Features
Due to the DC bus short circuit (ZKS), motors with permanent magnet excita‐
tion can be decelerated even if the electronic system of the drive is disturbed.
Personal injury caused by uncontrolled axis
motion!
WARNING
The DC bus short circuit protects machines in the case of drive errors. By it‐
self 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.
Install additional monitors and protective devices on the installation side.
Suggested Circuit
Connect the Bb contact of HLB in series with the Bb contacts of
the involved IndraDrive components so that the mains contactor
can be opened even if the module bus is defective.
Take the switching capacity of the involved contacts into account
(see technical data of the components).
Avoid switching on upon active DC bus short circuit!
Switch the N/O contact K1 before the ZKS1 input so that the DC
bus short circuit device is deactivated before the mains contactor
K1 switches power to the drive controller.
Risk of damage! Only apply mains voltage,
when 24V supply has been applied!
NOTICE
Only switch the mains voltage to HCS02, when the 24V supply has been ap‐
plied to HLB01 and HCS02.
When the 24V supply has been switched off, the DC bus short circuit device
in HLB01 is active and can damage HCS02.
