SINAMICS DCM DC Converter
74 Operating Instructions, 12/2018, A5E34763375A
Footnotes:
1)
The specified rated DC voltage can only be reached if the undervoltage does not
e
xceed 5%.
For 2Q devices, the specified rated DC voltage can on
ly be achieved if the α
G
limit
(p50150) is set to 5°.
Note:
Option L04 is available for armature infeed with extra
-low voltage (ordering data for
options, see Chapter "Type spectrum, ordering information (Page 25)").
2)
Values apply to rated DC output current
5)
Conditions:
The closed
-loop control (closed-loop PI control) constancy is related to the rated
m
otor speed and applies when the SINAMICS DC MASTER is at the operating
temper
ature. This is subject to the following preconditions:
•
Temperature changes of ±10 °K
Changes to the line voltage of +10% / -5% of the rated input voltage
•
Temperature coefficient of tachometer generator with temperature compensation:
0.15‰ every 10 °K (with analog tachometer generator only)
•
Constant setpoint (14-bit resolution)
