Fuji Drive Repair

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 drive, Control Concepts can fix it.

  • Low Voltage AC Drives
  • Medium Voltage AC Drives
  • Variable Frequency Drives (VFDs)
  • Motors
  • Servo Systems

What Do Fuji Drives Do?

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.

Common Drive Failures

  • Drive doesn’t run the motor
  • Drive keeps blowing fuses or tripping breakers
  • Loose connections
  • Non-functional cooling fans
  • Software or programming problems
  • Circuit board failure

Our Process


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 drive repair, service, and support.
