Parameter Description
p2181 Load monitoring response
7: A07891: Load monitoring, pump/fan blocked
A07892: Load monitoring, pump/fan without load
A07893: Load monitoring, pump leakage
8: F07894: Load monitoring, pump/fan blocked
F07895: Load monitoring, pump/fan without load
F07896: Load monitoring, pump leakage
p2182 Load monitoring speed threshold 1
● When using the control mode "U/f control" (p1300 < 10):
p2182 > 10% of the rated speed
● When using the control mode "encoderless vector control"
(p1300 = 20):
p2182 > p1755 (switchover speed, motor model)
The inverter interpo‐
lates linearly be‐
tween characteristic
points.
p2183 Load monitoring speed threshold 2
p2184 Load monitoring speed threshold 3
p2186 Load monitoring torque threshold 1, lower
p2188 Load monitoring torque threshold 2, lower
p2190 Load monitoring torque threshold 3, lower
p2191 Load monitoring torque threshold, no load
p2192 Load monitoring delay time
When using the control mode "encoderless vector control" (p1300 = 20):
● For operation with an induction motor: Set p2192 < 1 s or p1750.6 = 1 (the closed-
loop control does not change to open-loop controlled mode for blocked motor)
● For operation with synchronous and reluctance motors, the inverter sometimes
cannot detect a blocked motor.
p2193 = 4 or 5 Load monitoring configuration (factory setting: 1)
4: Pump monitoring: Differentiation between leakage and dry running
5: Fan monitoring: p2191 has no effect
