Description

Application
The SINAMICS DCM Control Module is mainly used for modifying and modernizing DC
drives in existing systems.
Many DC systems still use analog technology. When such systems are modified or
upgraded, the motor, mechanical parts, and power unit are retained, with just the closed-loop
control section being replaced by a SINAMICS DCM Control Module. This is a highly cost-
effective solution for those interested in a modern DC drive with the entire range of functions
associated with the fully digital units in the SINAMICS DCM range.
A simple process of parameter assignment is all that is required in terms of adapting the
product to the existing components' configuration.
The SINAMICS DCM Control Module contains a power unit for field supply with a rated
current of up to 40 A.
Structure
A striking feature of the SINAMICS DCM Control Module is its compact, space-saving
structure. Its compact design makes it easier to service, as the individual components are
readily accessible.
To make the most of the installation options existing systems have to offer, the SINAMICS
DCM Control Module can be divided into smaller parts (from the top down).
The printed circuit board for generating and distributing firing pulses can also be divided up
and, like the fuse monitoring and voltage measurement equipment, attached to the power
unit directly, either partly or completely outside the device, with a cable providing the
connection to the basic unit.
All connecting terminals can be accessed from the front.
The SINAMICS DCM Control Module has a Basic Operator Panel BOP20 in the front plate.
The BOP20 can be used
● To make all the settings that are required for commissioning
● To display all relevant measured values
● To display faults and alarms and acknowledge faults
● To switch the drive on and off
