Fuji Electric delivers high-performance inverters that offer automatically controlled motor operations and operating speeds for a wide variety of AC drive/variable frequency drive (VFD) applications.
No matter the type of Fuji drive, Control Concepts can fix it.
Fuji Electric AC drives provide precision control to operate at optimal speed throughout your application. They reduce overall power and energy use to decrease operating costs.
Fuji has drives that range from 1/8 HP (FRENIC-Mini (C2)) up to 1,000 HP VFDs (FRENIC-MEGA). In the lower power range, Fuji drives support both single-phase and triple-phase applications in an expanded range of rated voltages.
Fuji low voltage AC drives offer automatically controlled motor applications at high performance while the medium-voltage inverters are used for direct variable speed control for medium voltage motors.
Fuji also offers a comprehensive range of high efficiency motors and generators for all applications and a servo system that can be adapted to a wide range of motion control, from synchronization and interpolation to point-to-point positioning.
Fuji offers a line of low-voltage three-phase induction motors, geared motors, brake motors, and synchronous motors.
Small to medium capacity DC link inverters for facilities using a large number of small-to-medium capacity motors. Applications include steel, non-ferrous metals, paper, and general industry.
Medium to large capacity DC link inverters for facilities using medium-to-large capacity motors. Applications include rolling mills and winding machines.
Medium voltage direct output inverters are used for energy-saving operations. Applications include fans, blowers, pumps, and extruders.
Fuji also produces food and beverage distribution products including:
Control Concepts provides 24/7 service and support for all Fuji control products and solutions.
We check the motor drive and terminals for substandard connections which can be caused by anything from heat cycles and mechanical vibration to reusing or over-tightening torque screws.
We conduct diode and IGBT tests on the input/output power sections before applying power to the drive unit. This is to protect against further damage from a short.
We power up the unit and perform amp readings and output frequency tests, slowly increasing the voltage until the rated input voltage of the drive is reached.
If everything functions properly, we use the drive to run a motor through basic jog functions after backing up existing programs. If the motor does not run, we check the output voltages and current ratings going to the motor to check drive function for motor rotation.
Most drive failures can be avoided through preventative maintenance.
Control Concepts has over 30 years of experience in Fuji drive repair, service, and support. Call us for more information or to schedule service.
