SINAMICS DCP
24 Operating Instructions, 09/2019, A5E34382853K
Design
The SINAMICS DCP are compact devices and contain power units and open-loop/closed-
loop control electronics.
The open-loop/closed-loop control electronics comprise several modules.
The module that is visible after removing the front panel is called the CUD (Control Unit DC).
The connector board with interface X177 is plugged onto the CUD.
The power units are made up of semiconductor switches; the heat sink is grounded.
The devices are forced-ventilated, the air flow is from the bottom to the top.
The negative polarity (minus) cable is routed from side 1 to side 2, the current is controlled in
the positive polarity (plus) branch.
The devices are only approved for cabinet mounting, vertical installation.
Communication with the devices is via fieldbus (PROFIBUS or PROFINET) during normal
operation and STARTER for the parameter assignment and diagnostics.
Additional components
● CBE20 additional module
– The CBE20 additional module is inserted in the option module slot of the CUD. It
allows the SINAMICS DCP to be connected as IO device to a PROFINET network.
●
Memory card
– The memory card enables the functions described in Chapter "Memory card functions
(Page 158)".
●
For communication between two Control Units via DRIVE-CLiQ,
see the OALINK Function Manual
