Products Description
Control Techniques UNI1405 Unidrive Motion Drive Unit

Module Feature
UNI1405 is Unidrive classic series universal AC drive manufactured by Control Techniques,rated 4.0kW. It supports multiple control modes including V/F,open-loop vector,closed-loop flux vector and high performance servo control for Unimotor series brushless servo motors. It has flexible built-in digital and analog I/O and optional expansion slots for communication encoder cards. Widely applied in machine tools,packaging machines,material handling and general automation motion systems.
Working principle
Three-phase AC power passes through rectifier to form DC bus voltage. IGBT power module converts DC into adjustable frequency and voltage AC output. The drive receives command signals from upper controller, compares with encoder feedback signal to form closed-loop regulation,adjust torque,speed and position dynamically. Built-in braking transistor handles regenerative energy during motor deceleration.
