SINAMICS DCM
446 List Manual (LH8), 02/2015, 6RX1800-0ED76
Description: Sets the threshold for detecting that the line frequency has been overshot.
Dependency: Refer to: F60009
Caution: SINAMICS DCM DC converters are suitable for line frequencies from 50 Hz up to 60 Hz (rated value). Restricted
operation in the extended frequency range (20 Hz to 500 Hz) is possible on request.
If a SINAMICS DCM DC converter is continuously operated in the extended frequency range, then it would be
damaged or destroyed as a result of overheating.
The SINAMICS DCM Control Module is suitable for line frequencies from 20 Hz up to 500 Hz if it is operated with a
power unit designed for this frequency range.
Note: If the line frequency overshoots the value set here and does not fall back below it within the restart time set in
p50086, fault F60009 is triggered.
All the while the line frequency remains higher than the value set here, the drive is kept in operating state "o4".
Description: Sets the signal source for speed-dependent current limitation and current limitation from I2t monitoring.
Note: [0] = Speed-dependent current limitation
[1] = Current limitation from I2t monitoring
Description: Sets the threshold for the "Speed less then minimum speed" message.
Dependency: Refer to: p50371, p50593, r53025
Note: The "Speed less than minimum speed" message is available as follows:
- r53025.6 (not inverted)
- r53025.7 (inverted)
Description: Sets the hysteresis for the "Speed less then minimum speed" message.
