P8.11 1473 / (Reserve) 0
0 DS
1 - (Not permissible)
P8.12 714 / Underload protection at cut-off frequency 50.0
60.0
10.0 - 150.0 % of the motor torque.
The underload protection enables faults such as a torn drive belt
or the dry running of a pump to be detected without any additional
sensors.
The reaction to a detected underload can be set at P8.5.
The value set her determines the lowest permissible torque limit.
this function can also be used with output frequencies that are
above the cutoff frequency (P11.2, field weakening point).
Figure 88: Underload limit
Note: The value set here is reset automatically to the factory
setting (50.0 %) if the parameter for the motor rated current
(P7.1) is changed.
P8.13 715 / Underload protection at zero frequency. 10.0
5.0 - 150 % of the motor torque.
The value set here determines the lowest permissible torque limit
at zero frequency (range 0 - 5 Hz).
Note: The value set here is reset automatically to the factory
setting (50.0 %) if the parameter for the motor rated current
(P7.1) is changed.
P8.14 733 / Field bus error 2
Reaction to a fieldbus error if the fieldbus is set as active control
level (BUS) (P6.1 = 2, P6.17 = 2).
