Parallel Operation HMV
For mains connection, observe the control circuit for the mains connection.
Parallel operation of HMV01 supply units
●
is allowed with HMV01.1E supply units of the same type current
●
requires a mains choke for each supply unit (for current sharing)
●
does not increase the maximum allowed number of drive controllers or
axes when operated without mains filter
●
requires a control circuit master-slave; see chapter
For detailed information on derating and mounting, there is the specification
with document number 109-1261-4102-** (available on request).

Converter HCS as Supply Unit
General Information
Converters are designed for operating a single drive (see also individual sup‐
ply with HCS). In particular, the power supply with the capacitors in the DC
bus and the mains supply have been dimensioned with regard to operation
under rated conditions of the converter. When HCS converters are used as
supply units, the power of the converter (P
DC_cont
, P
DC_peak
) is available at the
DC bus connection for its own motor output and for further drive controllers.
Operating HCS converters as supply unit causes higher load of the capaci‐
tors in the DC bus.
Additional capacitors in the DC bus reduce the additional load by distributing
the current.
Damage to the converter!
NOTICE
Operation as supply unit additionally loads the converter. Observe the al‐
lowed peak power and continuous power (P
DC_cont
, P
DC_peak
) of the converter.
Operate additional capacitors C
DC_ext
at the DC bus and observe the notes on
project planning.
Central Supply - HCS Supply HCS or HMS/HMD Drive Controllers
Brief Description
The "central supply" via HCS converters is the mains supply with which the
converter supplies further drive controllers.
