Operating Instructions, 12/2018, A5E34763375A
Footnotes:
1)
The specified rated DC voltage can only be reached if the undervoltage does not
exceed 5%.
For 2Q devices, the specified rated DC voltage can only 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
motor speed and applies when the SINAMICS DC MASTER is at the operating
temperature. 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)
6)
For dynamic overload capability, see also Chapter "Dynamic overload capability of
the power unit (Page 591)"
