AC & DC Drives repair has been our core focus since the day our business was founded in 2004. We started with Yaskawa and Magnetek AC/DC drives and have grown our OEM brands to include others like Fanuc, Mitsubishi, Okuma, and many more.
We have over 50 years of combined experience working on industrial electronic repairs and can solve any problems you have with your drives.
Our modern and well-equipped facility provides us with all the necessary tools to evaluate and repair your AC or DC drive, from multi-meter and DC power supplies, to extensive soldering equipment and circuit analysis devices. Our large inventory of spare parts guarantees a quick turn-around on repairs. From failed inputs/outputs and your motor not running to over-current alarms and ground faults we have experience in repairing these problems. The products we service daily come from a wide range of applications: from Industrial CNC machines and hospital elevators to factory conveyor and industrial crane systems.
With that diversity in mind, Precision Zone has custom built simulators to fully test your AC or DC drive before the repair to identify the failures, and after repair to ensure the drive is ready for the actual production conditions.
Servo drives are electronic devices designed to control the operation of electric servomechanisms, most typically electric motors. Servo drives operate the motors by analyzing the signal from the motor feedback devices and continuously adjusting control signals to ensure desired motor performance within the closed loop system.
AC servo drives are paired with AC Servo motors. AC Servo Drives issue commands to the motor and receive feedback input to ensure the controlled motor performs a desired motion. AC Servo Drives continuously monitor the motor status by reading the feedback or sensor information. Feedback data signals the drive to perform continuous adjustments to achieve the needed velocity, torque, position, stiffness, damping, and feedback gain of the controlled AC servo motor.

Unlike AC servo drives, DC servo drives convert Alternating Current (AC) into Direct Current (DC) to control the DC Servo motors they are paired to. Single-phase DC servo drives operate in half-bridge mode by generating a half cycle of DC output from a single phase of AC input. Three-phase DC servo drives are equipped with 6 SCR’s that allow them to operate in full-bridge mode to generate a DC output from a 3 phase AC input.
