Chapter 7 Basic Functions
Operating command off, the inverter output is blocked. Be careful that the motor might continue rotating due to the
load inertia if the inverter output is blocked during high speed operation when the motor load has high inertia.
3) Flux Braking (Reducing decelerating time further without braking resistance or braking Unit)
Group Code No. Function Display Setting Display Unit
ADV 08 Stop Mode 3 Flux Braking -
If the decelerating time is short, over voltage trip might be caused by the regenerative energy from the motor. If you
apply flux braking, the decelerating time can be shortened because the regenerative energy is consumed by the
motor. However, be careful that damage might occur because of overheat of the motor if flux braking is applied to
loads which frequently decelerates.

Caution
When D.C. Braking is big or control time is too long,
overheating and malfunction may occur.
Caution
Since D.C Braking is a standard of rating current for pre-set
motor, please do not set over value of current of inverter’s
rating current. It may cause overheating and malfunction.
Caution
Do not use this function in case of load with frequent deceleration. It may cause overheating of the
motor and malfunction.
Caution
Stall prevention and Flux Braking are available only in case of deceleration. And, Flux Braking has a
priority. That means that Flux Braking operates when BIT3 of PRT-50 and Flux Braking of BAS-08
are set. In case of that deceleration time is too short or inertia is too big, over voltage trips may
occur.
