F 8 [DC Brake start frequency] - 0.1 ~ 60 5.00 Hz

F11 [DC Brake time] - 0 ~ 60 1.0 sec
ƒ
Set F4 - [Stop mode select] to 1.
ƒ
F 8: The frequency at which the DC brake will become active.
ƒ
F 9: Inverter output will hold for this time after F8 - [DC Brake start frequency] before
applying F10 - [DC Brake voltage].
ƒ
F10: Set this value as a percent of H33 – [Motor rated current].
ƒ
F11: It sets the time for F10 - [DC Brake voltage] to be applied to the motor after F 9 - [DC
Brake wait time].
ჹ
Caution:
If excessive DC Brake voltage is set or DC Brake time is set too long, it may cause motor
overheating and damage to the motor.
Setting F10 or F11 to 0 will disable DC brake.
F 9 – [DC Brake Wait time]: When load inertia
is large or F 8 – [DC Brake Start Frequency] is
high, over current trip may occur. It can be
prevented using F9.
In case of DC brake at high load inertia and frequency, change the DC brake
controller gain according to H37 set value.
