74 Planning the electrical installation
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.
• If the installation is equipped with a main contactor, prevent its tripping at the input
power break. For example, use a time delay relay (hold) in the contactor control
circuit.
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.
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.
If there are power factor compensation capacitors in parallel with the three phase
input of the drive:
1. Do not connect a high-power capacitor to the power line while the drive is
connected. The connection will cause voltage transients that may trip or even
damage the drive.
2. If capacitor load is increased/decreased step by step when the AC drive is
connected to the power line, ensure that the connection steps are low enough not
to cause voltage transients that would trip the drive.
3. Check that the power factor compensation unit is suitable for use in systems with
AC drives, ie, harmonic generating loads. In such systems, the compensation unit
should typically be equipped with a blocking reactor or harmonic filter.
Using a contactor between the drive and the motor
Implementing the control of the output contactor depends on how you select the drive
to operate. See also section
