Learning Protection Features
Code Description
Pr.51 Stall
Freq 1-
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).
Note
Stall protection and flux braking operate together only during deceleration. Turn on the third and
fourth bits of Pr.50 (11xx) to achieve the shortest and most stable deceleration performance without
triggering an overvoltage fault for loads with high inertia and short deceleration times. Do not use
this function when frequent deceleration of the load is required, as the motor can overheat and may
be damaged.
When using a Dynamic Brake resistor, the motor may vibrate under the Flux braking operation. In
this case, turn off the Flux braking (Pr.50, 0xxx).
•
Acceleration stops when stall protection operates during acceleration. This may make the actual
acceleration time longer than the preset acceleration time.
•
Use caution when decelerating while using stall protection as the deceleration time can take
longer than the time set.
•
When the motor is operating, Stall Level 1 applies and determines the operation of stall
protection.
