Operating HMU05 together with HMS01/HMD01
Topologies
HMS01 or HMD01 drive controllers of the IndraDrive M product range may
only be operated at HMU05 supply units, if at least one HLL DC bus choke
with the corresponding Y capacitor pairs is used (regarding Y capacitor pairs,
see also
chapter "HMU05 systems for high leakage capacitances" on page
There are two different topologies:
●
HMU05 systems without a central DC bus choke
●
HMU05 systems with a central DC bus choke
Concerning the tapered cross sections of the DC bus bars, please observe
the information on DC bus fuses: See
chapter 11.3 "DC bus fuses" on page
.
With the drive firmware you can configure an inverter as a module bus mas‐
ter. Integrate the relay contact of the module bus master configured as a Bb
contact in the power supply control circuit in such a way that opening the re‐
lay contact causes the power to be disconnected.
