Declaration of Conformity

See page 197.

Implementing the Power-loss ride-through function

Implement the power-loss ride-through function as follows:
Check that the power-loss ride-through function of the drive is enabled with parameter
30.31 Undervoltage control in the ACS880 primary control program.
WARNING! Make sure that the flying restart of the motor will not cause any
danger. If you are in doubt, do not implement the Power-loss ride-through
function.

Units with main contactor (option +F250)


The main contactor of the drive opens in a power-loss situation. When the power returns,
the contactor closes. However, if the power-loss situation lasts so long that the drive trips
on undervoltage, it must be reset and started again to continue operation. If the power-loss
situation lasts so long that the buffering module (C22, see page
main contactor remains open and the drive operates only after reset and a new start.
With external uninterruptible control voltage (option +G307), the main contactor remains
closed in power loss situations. If the power-loss situation lasts so long that the drive trips
on undervoltage, it must be reset and started again to continue operation.

Supplying power for the auxiliary circuits

The drive is equipped with an auxiliary control voltage transformer which supplies control
voltage, for example, for the control devices and cabinet fan(s).
The drive provides terminals for connecting external
•
230 V or 115 V uniterruptible power supply (option +G307) to the control unit and
control devices when the drive is not running
•
power supply for cabinet heater (option +G300) and lighting (option +G301)
•
power supply for motor space heater output (option +G313).
Using power factor compensation capacitors with the
drive
Power factor compensation is not needed with AC drives. However, if a drive is to be
connected in a system with compensation capacitors installed, note the following
restrictions.
WARNING! Do not connect power factor compensation capacitors or harmonic
filters to the motor cables (between the drive and the motor). They are not meant
to be used with AC drives and can cause permanent damage to the drive or
themselves.
