High-performance drives for efficient operations

A TI Systems has introduced the Frenic range of high- performance drives from Fuji Electric. The drives enable automatically controlled motor operations with operating speeds for a variety of applications. Precision control ensures that the Frenic drives operate at optimal speed, reducing overall power and energy usage. The drives are easy to install, start up and maintain, and offer a ten-year design life, supported by on-board insulated-gate bipolar transistors (IGBTs), cooling fans, dc bus capacitors and an optimised dc bus. Fuji Electric ac drives from ATI Systems include the: - Fuji Frenic-ACE (0,1 - 315 kW) Fuji Frenic-ACE These drives offer good value and performance through optimal design. They can be used in applications ranging from fans and pumps to specialised machinery and can control induction motors in open and closed loop and permanent magnet ac (PMAC) motors, in open loop. The Frenic-ACE drives feature a full range of commu- nications interfaces including: Profibus DP, DeviceNet, Profinet, EtherCAT, Ethernet IP, Modbus RTU, Modbus TCP, and CANopen. Users can develop their own custom appli- cations using the built-in Custom Function Logic. Fuji Frenic-ACE Solar The Frenic-ACE Solar with high reliability and long lifespan offers quiet, automatic functions and is easily extendable. Fuji solar pumping solutions from ATI Systems offer simple installation, easy start-up and minimum maintenance. They are designed to control induction as well as permanent magnet ac motors and offer excellent maximum power point tracking (MPPT) functionality. Fuji Frenic-ACE H The Frenic-ACE H provides energy savings for HVAC and water-pumping applications. Its user friendliness, network compatibility and long-term reliability support the long-term performance of systems. Customised logic enables the user to tailor the drive’s functionalities to specific requirements in each application. Fuji Frenic-Lift AC Drive This specialist lift drive offers a full range of motor control modes for induction, permanent magnet and gearless machines. It features stationary auto-tune without the - Fuji Frenic-ACE Solar (0,4 - 280 kW) - Fuji Frenic-ACE H (0,75 - 315 kW) - Fuji Frenic-Lift AC Drive (2,2 - 45 kW) - and the Fuji Frenic-VG (0,75 - 3 MW).

need to loosen lift cables, and a contactor-less safe torque off (STO) solution.

Fuji Frenic-VG The Fuji Frenic-VG drive features easier and more user- friendly maintenance as well as environmental friendliness and safety. The Frenic-VG Series is available as either a unit type or stack type. Drives in crane applications A full range of drives for cranes is available, ranging from 0.4 kW to 3 MW, 3-phase 400 V AC power supply. They feature a 200% overload withstand for three minutes or 150% for one minute, built-in EMC filter up to 630 kW, built-in braking circuit up to 160 kW, and excellent vector control with speed sensor. They also feature powerful dynamic torque vector control for open loop applications and adaptable speed, depending on the load function (load adaptive control). A single inverter can control up to four motors. A stack-type topology is available for larger capacities. □

The Fuji Electric range of high-performance Frenic drives is available from ATI Systems.
