Value:
★ Disable (DISABLE)
Enable (ENABLE)
DC brake and start (DC BRAKE AND START)
Function:
This function makes it possible for the drive to ‘catch’ a rotating motor
when the drive is started. The drive will sense the speed of rotation and
direction of rotation of the motor and synchronize with it.
This function is active whenever a start command is present.
For the drive to catch the spinning motor, the motor speed must be
lower than the maximum frequency set in parameter 202.
Description of choice:
Select Disable if this function is not required.
Select Enable if the drive is to ‘catch’ and control a rotating motor.
Select DC brake and start if the drive is to brake the motor by means of
the DC brake first, and then start. Ensure that parameters 114 through
116, DC Braking, are set appropriately. Select DC brake and start if the
motor may be externally driven at a significant speed in the reverse
direction.
For fan applications, factory setting for Flying
Start is Enable. For pump applications, factory
setting for Flying Start is Disable.
