54 Unidrive SP Advanced User Guide
www.controltechniques.com Issue Number: 7
If the speed feedback (Pr 3.02) 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_FREQ_MAX.
In servo mode the motor speed and the motor voltage can be monitored to detect that the motor is accelerating in an uncontrolled way because the
motor phasing angle has not been set up correctly in Pr 3.25 (Pr 21.20 if motor map 2 is selected). If the overspeed threshold is set to zero phasing
angle error monitoring is enabled. If the overspeed threshold is set to any other value this feature is disabled.
See Pr 3.06 and Pr 3.07 on page 53.
