Note that when there is high inertia on the output side and the motor is operating at high speed,
the load‘s inertia will cause the motor to continue rotating even if the inverter output is blocked
4.17.4 Power Braking
When the inverter‘s DC voltage rises above a specified level due to motor regenerated
energy a control is made to either adjust the deceleration gradient level or reaccelerate the
motor in order to reduce the regenerated energy. Power braking can be used when short
deceleration times are needed without brake resistors, or when optimum deceleration is
needed without causing an over voltage fault trip.
•
To prevent overheating or damaging the motor, do not apply power braking to the loads that
require frequent deceleration.
•
Stall prevention and power braking only operate during deceleration, and power braking
takes priority over stall prevention. In other words, when both bit 3 of PRT-50 (stall
prevention and flux braking) and ADV-08 (braking options) are set, power braking will take
precedence and operate.
•
Note that if deceleration time is too short or inertia of the load is too great, an overvoltage
fault trip may occur.
•
Note that if a free run stop is used, the actual deceleration time can be longer than the pre-
set deceleration time.
