deceleration may be reduced because regenerative energy
is expended at the motor.

and flux braking
during
deceleration Stall protection and flux braking operate
together during deceleration to achieve the
shortest and most stable deceleration
performance.

– 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).
PRT-59 Flux
Brake Kp
A gain used to decelerate without over voltage fault trip. It compensates
for the inverter output voltage.
