Overspeed threshold

Bit SP
Coding
Range 0 to 10,000 rpm
Default 0
Update rate Background read
If the speed feedback (Pr 3.02 {di05, 0.40}) exceeds this level in either direction an overspeed trip is produced. If this parameter is set to zero, the
overspeed threshold is automatically set to 1.2 x SPEED_MAX.
3.09 Absolute "at speed" select
Bit SP
Coding
1
Default 0
Update rate Background read
"At speed" flag (Pr 10.06) is set if the speed feedback (Pr 3.02 {di05, 0.40}) is on the boundaries or within the at speed window. Flags Pr 10.07 and Pr
10.05 are set if the reference is above or below the window respectively.
If Pr 3.09 = 0 reference window mode is used and the "at speed" condition is true if
(|Pr 1.03 {di02, 0.37}| - Pr 3.06) δ |Pr 3.02 {di05, 0.40}| δ (|Pr 1.03 {di02, 0.37}| + Pr 3.07)
(If the lower limit is less than zero then zero is used as the lower limit.)
If Pr 3.09 = 1 absolute window mode is used and the "at speed" condition is true if
Pr 3.06 δ |Pr 3.02 {di05, 0.40}| δ Pr 3.07
