Learning Protection Features
Stall Prevention Function and Flux Braking Setting Details
•
Use caution when decelerating while using stall protection since the deceleration time can take
longer than the time set, depending on the load. Acceleration stops when stall protection
operates during acceleration. This may make the actual acceleration time longer than the preset
acceleration time.
•
When the motor is operating, Stall Level 1 applies and determines the operation of stall
protection.
•
If the input voltage exceeds the nominal voltage, there is a possibility that the deceleration stall
does not work properly.
PRT-59 Flux Brake
Kp
A gain used to decelerate without over voltage fault trip. It compensates for
the inverter output voltage.
Note
Stall protection and flux braking operate together only during deceleration. Turn on the third and
fourth bits of PRT-50 (Stall Prevention) to achieve the shortest and most stable deceleration
performance without triggering an over voltage fault trip 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 be easily damaged.
