PARAMETER DESCRIPTIONS
This is the maximum time for a stall stage. An internal counter counts the stall time. If the
value of the counter goes above this limit, the protection causes the drive to trip (see ID709).
See Chapter 8.5 Parameters of stall protection (IDs 709 to 712).

712 STALL FREQUENCY LIMIT 234567 (2.7.16)
The frequency can be set between 1-f
For a stall state to occur, the output frequency must be below this limit for a certain time.
See Chapter 8.5 Parameters of stall protection (IDs 709 to 712).

See Chapter 8.6 Parameters of underload protection (IDs 713 to 716).
714 UNDERLOAD PROTECTION, FIELD WEAKENING AREA LOAD 234567 (2.7.18)
You can set the value of this parameter between 10.0—150.0 % x T
limit for the minimum torque when the output frequency is above the field weakening point.
If you change parameter ID113 (Motor nominal current), this parameter goes automatically
back to its default value. See Chapter 8.6 Parameters of underload protection (IDs 713 to 716).
