7.2.8 Flux Braking
P3.4.5.1 F
LUX BRAKING
Instead of DC braking, flux braking is a useful way to raise the braking capacity in cases where ad-
ditional 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 con-
trolled 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 intermittently
to avoid motor damage.
7.2.9 Digital inputs
P3.5.1.15 R
UN ENABLE
Contact open: Start of motor disabled
Contact closed: Start of motor enabled
The AC drive is stopped according to the selected function at P3.2.5. The follower drive will always
coast to stop.
P3.5.1.16 R
UN INTERLOCK 1
P3.5.1.17 R
UN INTERLOCK 2
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.
