RAKING
Instead of DC braking, flux braking is a useful way to raise the braking capacity in cases where
additional brake resistors are not needed.
When braking is needed, the frequency is reduced and the flux in the motor is increased, which
in turn increases the motor's capability to brake. Unlike DC braking, the motor speed remains
controlled during braking.
The flux braking can be set ON or OFF.
NOTE : Flux braking converts the energy into heat at the motor, and should be used intermit-
tently to avoid motor damage.

The AC drive is stopped according to the selected function at P3.2.5. The follower drive will al-
ways coast to stop.

The drive cannot be started if any of the interlocks are open.
The function could be used for a damper interlock, preventing the drive to start with damper
closed.
P3.5.1.52 E
NERGY COUNTER RESET
This parameter enables reset of Energy counter.
P3.5.1.53 M
AINS SUPPLY ON
In case the drive is fed by mains supply, the controller knows this situation through a specific
digital input.
The functions related to DC voltage (start enable, MPPT) are disabled in this condition.
