SINAMICS DCM Control Module
Operating Instructions, 06.2010, C98130-A7067-A1-02-7619
1)
The field supply voltage may be below the rated field voltage (setting for p50078.1,
input voltages of up to 85 V are permitted). The output voltage decreases
accordingly.
This output voltage can no longer be achieved at voltages below 95% of the rated
supply voltage.
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 °C
• 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 °C (with analog tachometer generator only)
• Constant setpoint (14-bit resolution)
The option of operating with an extended frequency range can be provided on
request.
