cost. Site standardization may also be a factor.

Active Input and

Regeneration

Active inputs for harmonic elimination and regenerating excess energy can be configured with standard drive modules, configured as motoring or regenerating.

12 Pulse Input Current

Multi-pulse rectifiers can be configured (12, 18 and 24 etc.), to minimise input harmonics and help to meet local supply authority regulations.

Common DC bus

Drives from the Unidrive and Commander families can be connected on a common DC bus system, in order to circulate energy between drives with opposing energy flow, supplied from a controlled rectifier input (SPMC), an active input (SPMA or SPMD) or an existing DC source.
