6 - Parameter Descriptions
F11: DC Brake Time
Range: 0 - 60 sec. (Default: 1.0sec.)
Description: This parameter sets the time taken to apply DC current to a motor while
motor is at a stop. It sets the time for F10 (DC Brake Voltage) to be applied
to the motor after F9 (DC Brake Wait Time).
•
To stop the motor by DC brake, set F4 (Stop mode select, page 67) to 1.
•
Setting F10 or F11 to 0 will disable DC Brake.
•
In case of DC brake at high load inertia and frequency, change the DC
brake controller gain according to H37 (Load inertia ratio, page 94) set
value.
F12: DC Brake Start Voltage
Range: 0 - 200 % (Default: 50%)
Description: This parameter sets the amount of DC voltage before a motor starts to run. It
is set in percent of H33 (Motor Rated Current), (see parameter F13).
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.
