Parameters
p2192
p2193 = 1
In applications with fans, pumps or compressors with the flow characteristic, the torque
follows the speed according to a specific characteristic. An insufficient torque for fans
indicates that the power transmission from the motor to the load is interrupted. For pumps,
insufficient torque can indicate a leakage or dry-running.
If the torque and speed lie in the impermissible range longer than time p2192, the inverter
reacts as specified in p2181.
For applications with pumps (p2193 = 4), the inverter detects the following states of the
driven load:
● Blocked
● Leakage
● Dry running
For applications with fans or compressors (p2193 = 5), the inverter detects the following
states of the driven load:
● Blocked
● Torn belt
The monitoring is not active below speed threshold 1 and above speed threshold 3.
When using the control mode "U/f control" (p1300 < 10), the "Blocking protection" function
becomes active when the current limit is reached.
