Stall protection and flux braking operate together
during deceleration to achieve the shortest and most
stable deceleration performance.
Pr.58 Stall Level 4
Additional stall protection levels can be configured for different frequencies, based
on the load type. As shown in the graph below, the stall level can be set above the
base frequency. The lower and upper limits are set using numbers that correspond
in ascending order. For example, the range for Stall Frequency 2 (Stall Freq 2)
becomes the lower limit for Stall Frequency 1 (Stall Freq 1) and the upper limit for
Stall Frequency 3 (Stall Freq 3).
