Operating Instructions

6.30.3 Blocking protection
In applications with extruders or mixers, the motor can block for an excessive mechanical load.
For a blocked motor, the motor current corresponds to the set current limit without the speed
reaching the specified setpoint.
If the speed lies below the speed threshold p2175 for the time p2177 while the motor current
reaches the current limit, the inverter signals "Motor blocked" and fault F07900.
Parameter Description
r0063 Actual speed value [rpm]
[0] = Unsmoothed
[1] = Smoothed with p0045
p2175 Motor blocked speed threshold (factory setting: 120 rpm)
p2175 = 0: Blocking protection deactivated
p2177 Motor blocked delay time (factory setting: 3 s)
r2198 Status word monitoring 2
r2198.06 = 1: Motor blocked
