Energy management
If the supply network is impaired due to high voltage fluctuations, you must consider the specifications of the economy variable frequency drive and the speed range of the connected motor.
- ►Observe the upper limit value of the tolerance of the rated supply voltage.
- ►Check whether a reduction in speed is permissible due to a lack of voltage.
- ►If the supply network does not meet the specifications for operating a economy variable frequency drive, use isolating transformers, mains chokes, mains filters and other measures to achieve the required specifications.
The economy variable frequency drive AF1000 stores energy in the internal DC link. If the regenerative energy generated when braking a connected motor is higher than the energy that can be stored in the DC link, an external braking resistor is required.
For existing drive systems, you can determine the utilization of the braking resistor using the measuring and diagnostic functions available in the drive system and transfer the values.
