2.2 List of parameters
Description: Sets the threshold for tachometer interruption monitoring.
Dependency: Refer to: F60042
Note: For p50357 = 100 %, the tachometer interruption monitoring is not active!
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.
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.
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".
