Overview
The series of SINAMICS DC MASTER DC Converters includes
the following components:
•
Electronics module with Control Unit (CUD) and slot for expan-
sion using another CUD (in a cradle that can be swiveled out)
•
Power section with thyristors in a fully-controlled three-phase
bridge circuit configuration (two-quadrant drive: B6C or four-
quadrant drive: (B6) A (B6) C)
2)
•
Fan (up to 125 A: self-ventilated)
•
Single-quadrant field power section with integrated free-
wheeling circuit (optionally, also without field or as two-
quadrant field for highly dynamic field current changes with
integrated field overvoltage protection)
•
Electronics power supply
•
Standard BOP20 operator panel (AOP30 Advanced Operator
Panel as accessory)

1)
Conditions:
The closed-loop control (PI control) stability is referred to the rated motor
speed and applies when the SINAMICS DC MASTER is in the warm
operating condition. This is based on the following preconditions:
• Temperature changes of
±
10 °C
• Line supply voltage changes of +10 % / -5 % of the rated input voltage
• Temperature coefficient of the tachometer generator with temperature
compensation 0.15 ‰ every 10 °C (for analog tachometer generators
only)
• Constant setpoint
2)
In two-quadrant operation, the drive can operate in "driving" mode in one
direction of rotation and in "braking" mode with regenerative feedback in
the opposite direction of rotation. In four-quadrant operation, the drive can
operate in "driving" mode and in "braking" mode with regenerative feed-
back in both directions of rotation.
