Unidrive Classic 4kW Inverter 380...480V AC 3PH 9.5A

About this product

Here is all you need to know


The Control Techniques Unidrive UNI1405 is a 4kW, 380...480V AC AC inverter. Named Unidrive because of its universal nature, the drive can operate in five modes including Open Loop V/F Control, Open Loop Space Vector Control, Closed Loop Flux Vector Control, Servo and Regeneration. The inverter can be configured in minutes for a variety of industry standard applications thanks to its pre-configured application parameter sets known as MACROs. Although it has since been replaced by the Unidrive SP, the original Unidrive gave users the benefits of simplicity, ease of use and flexibility. As official distributors for Control Techniques, Northern Industrial can supply the now obsolete Unidrive UNI1405, as well as the option modules that are compatible with the variable speed drive.

Easy to Use

Configuring the 4kW Unidrive is simple due to the parameter sets which come pre-configured. These parameter sets are also known as MACROs.. You can also view and edit parameter values quickly and easily using the Unisoft commissioning software and get your motor turning in minutes with the quick start guide. Multiple drive set up is also made easy due to the optional cloning module which allows the user to copy parameters. The pre-configured parameter sets (MACROs) include:

  • General Purpose
  • Easy Mode
  • Motorised Potentiometer
  • Preset Frequencies/Speeds
  • Torque Control
  • PID Control
  • Axis Limit Control
  • Brake Control
  • Electrical Gearbox
