6.2.1 Information on design and operation
In order to connect the capacitors of multiple drive controllers, you need a separate Quick DC-Link module of type DL6B for
each drive controller in the group.
Information
Note that Quick DC-Link can be subject to system or country-specific standards.
Central braking resistor
During a controlled emergency stop, all drive controllers may brake at the same time. During the design phase, check
whether a central braking resistor is necessary to be able to stop certain system parts safely within a prescribed time.
Electrical data of the drive controllers
The electrical data of the individual drive controller types must be observed in the design and operation of Quick DC-Link,
including the following in particular:
§ Self-capacitance C
PU
§ Charging capacity C
maxPU
§ Nominal input current I
1N,PU
§ Derating of the nominal input current
You can find the values in the technical data for the drive controllers.
Maximum voltage and maximum current
The maximum DC link voltage is 750V
DC
and the maximum permitted overall current is 200A.
Protective measures
Note the information in the following chapters:
§ Power grid supply in case of parallel connection [}73]
§ Line fuse in case of parallel connection [}75]
§ Grid connection in case of parallel connection [}76]
