10.344 (ID 712) Stall Frequency Limit
Location in the menu:
P2.7.16
(Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application
Use this parameter to set the limit below which the output frequency of the drive must stay for a stall stage to occur.
The frequency can be set between 1-f
max
(
ID 102
).
For a stall state to occur, the output frequency must be below this limit for a certain time.
See
10.622 Parameters of Stall Protection (IDs 709–712)
.
10.345 (ID 713) Underload Protection
Location in the menu:
P2.7.17
(Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to select the response of the drive to an 'Underload' fault.
See
10.623 Parameters of Underload Protection (IDs 713–716)
10.346 (ID 714) Underload Protection: Field Weakening Area Load
Location in the menu:
P2.7.18
(Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application
Use this parameter to set the minimum torque that the motor needs when the output frequency of the drive is higher than the
frequency of the weakening point. It is possible set the value of this parameter between 10.0% and 150.0% x T
nMotor
. This value is
the limit for the minimum torque when the output frequency is above the field weakening point.
Changing parameter
ID 113
(Motor nominal current) restores this parameter automatically to its default value. See
ters of Underload Protection (IDs 713–716)
.
