Tachometer Interruption Monitoring Threshold / Tacho_Mon Thresh; Line Monitoring Undervoltage Delay Time / V_Under T_Del; Line Monitoring Overvoltage Delay Time / Line V_Over T_Del; Line Frequency Minimum Threshold / F_Line Min Thresh - Siemens SINAMICS DCM List Manual

p50357[0...n]

Tachometer interruption monitoring threshold / Tacho_mon thresh

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
10 [%]
Description: Sets the threshold for tachometer interruption monitoring.
Dependency: Refer to: F60042
Note: For p50357 = 100 %, the tachometer interruption monitoring is not active!
p50361[0...n]

Line monitoring undervoltage delay time / V_under t_del

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [ms]
Description: Sets the delay time for undervoltage detection in the context of line monitoring.
Note: This time starts when undervoltage is detected. While this delay time is running, firing pulses are emitted; at the end
of this time, fault F60006 is triggered.
If a time has been set for automatic restart (p50086), it will not begin until the time set here has elapsed.
p50362[0...n]

Line monitoring overvoltage delay time / Line V_over t_del

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [ms]
Description: Sets the delay time for overvoltage monitoring in the context of line monitoring.
Dependency: Refer to: F60007
Note: The triggering of fault F60007 (line overvoltage) is delayed by the time set at this parameter.
Firing pulses are emitted while this time is running. If a time has been set for automatic restart (p50086), it will not
begin until the time set here has elapsed.
p50363[0...n]

Line frequency minimum threshold / f_line min thresh

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
23.0 [Hz]
Description: Sets the threshold for detecting that the line frequency has been undershot.
Dependency: Refer to: F60008
Note: If the line frequency undershoots the value set here and does not rise back above it within the restart time set in
p50086, fault F60008 is triggered.
All the while the line frequency remains lower than the value set here, the drive is kept in operating state "o4".
