P13.12 STALL TIME
This time can be set between 0.00 and 300.00s.
This is the maximum time allowed for a stall stage. The stall time is counted
by an internal up/down counter.
If the stall time counter value goes above this limit the protection will cause a
trip (see P13.5).See Figure 9.21.

P13.14 UNDERLOAD PROTECTION: FIELD WEAKENING AREA LOAD
The torque limit can be set between 10.0-150.0 % x TnMotor.
This parameter gives the value for the minimum torque allowed when the out-
put frequency is above the field weakening point. If you change parameter P1.4
(Motor nominal current) this parameter is automatically restored to the de-
fault value.
P13.16 UNDERLOAD PROTECTION: TIME LIMIT
This time can be set between 2.0 and 600.0 s.
