Chapter 7 Basic Functions
7.1.17 Stop method selection (Changing stop method)
You can choose the method of stopping the motor when the inverter is given a stop command during operation.
1) Decelerating Stop
Group Code No. Function Display Setting Display Unit
ADV 08 Stop Mode 0 Dec -
This is a normal decelerating method. If no particular function is selected, the inverter decelerates to 0Hz and stops as
follows.
7.1.18 Stop after D.C. braking
(in order to stop the motor when decelerating with direct current in pre-set frequency)
If frequency reaches the set one, D.C. Braking stops the motor.

17 Dc-Brake Freq - 5.00 0~60 -
If the frequency reaches pre-set frequency during deceleration, the motor is stopped by D.C. braking. Start decelerating
with stop command and put direct voltage into the motor to stop if frequency reaches ADV-17 Dc-Brake Freq.
ADV-14 Dc-Block Time : sets the time to block output of inverter before D.C. Braking. When inertia of load is big or
ADV-17 Dc-Brake Freq is high, over current trips may occur due to current voltage to the motor. Therefore, it
prevents from over current trips by controlling this time.
ADV-15 Dc-Brake Time : sets the time to put current voltage to the motor.
ADV-16 Dc-Brake Level : controls D.C. Braking. Rating current of the motor is a standard.
ADV-17 Dc-Brake Freq : sets frequency to start D.C. Braking. It starts D.C. Braking when reaching
pre-set frequency after inverter starts decelerating.
Dec Time
Notice
When setting lower than frequence of D.C. Braking using Dwell frequency, Dwell operation is not available. Only D.C. Braking
operates.
