Learning Protection Features
0100
Stall protection
during
deceleration
The inverter decelerates and keeps the DC link
voltage below a certain level to prevent an over
voltage fault trip during deceleration. As a result,
deceleration times can be longer than the set time
depending on the load.
1000
Flux braking
during
deceleration
When using flux braking, deceleration time may
be reduced because regenerative energy is
expended at the motor.
1100
Stall protection
and flux braking
during
deceleration
Stall protection and flux braking operate together
during deceleration to achieve the shortest and
most stable deceleration performance.

1– PRT-58 Stall
Leve l4
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).
