Control Techniques Unidrive classic UNI1405 4KW, 3 phase 380-480VAC inverter drive. The drive is able to operate in five modes including Open Loop Space Vector Control, Open Loop V/F Control, Closed Loop Flux Vector Control, Servo and Regeneration. This inverter can be quickly and easily set up for a number of industry standard applications thanks to its pre-configured application parameter sets known as MACROs. The Unidrive Classic range has been obsolete for a number of years having first been replaced by the Unidrive SP, which itself is now obsolete, and subsequently replaced by the Unidrive M700. Despite the newer drives being available, replacing the original Unidrive can sometimes prove to be difficult, particularly when comms or application expansion modules are being utilised, meaning to replace one drive an entire system may need to be replaced or reprogrammed. With many years experience repairing the UNI1405, AFi Systems can supply this model, as well as the option modules that are compatible with the variable speed drive from stock fully tested with our standard 2 year warranty. In a breakdown situation we know that speed is key, so if your requirement is urgent give us a call for the fastest possible delivery.
