F8: DC Brake Start Frequency
Range:
0.1 - 60 Hz (Default: 5.00Hz)
Description:
This parameter sets DC brake start frequency at which the drive starts to
output DC voltage during deceleration. It cannot be set below F23 (Start
Frequency, page 72).
•
To stop motor by DC brake, set F4 (Stop mode select) to 1.
•
Only displayed when F4 is set to 1 (DC Brake to stop).
F9: DC Brake Wait Time
Range:
0 - 60 sec. (Default: 0.1sec)
Description:
This is the amount of time the drive waits before outputting voltage after the
VFD has gone below the frequency in F8 (DC Brake start frequency) before
applying F10 (DC Brake voltage).
•
When load inertia is large or F8 (DC Brake Start Frequency) is high, over
current trip may occur. It can be prevented using F9 (DC Brake Wait
Time).
•
To stop motor by DC brake, set F4 (Stop mode select, page 67) to 1.
F10: DC Brake Voltage
Range: 0 - 200 % (Default: 50%)
Description: This parameter sets the amount of DC voltage applied to the motor. It is set
in percent of H33 (Motor Rated Current).
•
Setting F10 or F11 to 0 will disable DC Brake.
•
To stop motor by DC brake, set F4 (Stop mode select, page 67) to 1.
