The supply voltage for the armature/field can lie below the rated armature/field
voltage (set in p50078):
Permissible input voltage:
≥50 V for devices with rated voltage 400 V, 480 V and 575 V
≥100 V for units with rated voltage 690 V, 830 V and 950 V
The output voltage is reduced accordingly.
The specified output DC voltage can be ensured for an undervoltage up to 95 % of
the line voltage (rated supply voltage of the armature/field).
Note:
Option L04 is available for armature infeed with extra-low voltage (ordering data for
options, see Chapter 2)
Values apply to rated DC output current
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)
For dynamic overload capability, see also Chapter 10
see also Chapter "Installation notes for design according to UL 508C"
The option of operating in an extended frequency range can be provided on request.
