Description
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
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 con-
•
trol" (p1300 = 20):
p2182 > p1755 (switchover speed, motor model)
Load monitoring speed threshold 2
Load monitoring speed threshold 3
Load monitoring torque threshold 1, lower
Load monitoring torque threshold 2, lower
Load monitoring torque threshold 3, lower
Load monitoring torque threshold, no load
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.

4: Pump monitoring: Differentiation between leakage and dry running
5: Fan monitoring: p2191 has no effect
