The performance features for the UNI1401 include advanced auto-tuning abilities which help enhance and escalate the performance of the motor shaft and at the same time are able to keep the noise level of the motor down during the operation of the motor. It uses Intelligent Thermal modeling to maximize performance. Its Flux Vector control on this unit is second to none with the use of enhanced control algorithms. You get full internal protection as it stores the last 10 trips the machine logged.

This unit is fully programmable and the voltage, as well as the current, have options you are able to select. 

There are several benefits to this drive including the ease of setting parameters on your unidrive with easy configuration, and you can use the pre-configured settings. The Unisoft software makes viewing and editing your parameter settings a breeze. The quick start guide helps you get the motor shaft working in a snap. The terminals are simple to use with their easy connect pluggable features.

These key features are what set the Control Techniques Unidrive 1401 apart from other drives. The Unidrive is dual rated for both heavy and normal duty as it applies to continuous current rating and short-term overload limits. It satisfies Low Voltage Directive 73/23/EEC, the Electromagnetic Compatibility (EMC) Directive 89/336/EEC, and the CE Marking directive 93/68/EEC. 

Truly impressive, this unit is a universal drive and is able to be configured for your standard applications in a short time. That translates to savings in both time and money. It has the highest ratio available in terms of power to size. That helps reduce panel costs.
