Yaskawa is the world’s largest manufacturer of AC drives and motion control products, including adjustable frequency drives.
- Industrial AC drives
- HVAC drives
- Specialty pump drives
- Elevator drives
- Medium voltage drives
Who Is Yaskawa?
Since 1915, Yaskawa Electric has served the world’s needs for products to improve global productivity through automation. Yaskawa has relied on partners who sell their drives under the partner company’s label, so it does not have the same name recognition of other drive manufacturing companies, including MagneTek, which Yaskawa bought in 2001 and began manufacturing products under its own name.
Yaskawa manufacturs a wide variety of industrial AC drives including general purpose drives, microdrives, and fan and pump drives. Each offers specific functionality is designed to control different types of motors. Yaskawa also provides elevator component drives and specialty pump drives as well as variable frequency HVAC drives.
General Purpose Drives
A general purpose drive is used in pumps, fans, and conveyors. It is recommended for its simple installation and programming and for situations that do not require custom engineering.
General purpose drives are easy to set up and operate, providing several built-in features.
Industry Specific Drives
Yaskawa produces drives for specific industries:
- Booster/Lift Stations
- Geothermal Systems
- Desalinization Process Plants
- Centrifugal and Vertical Turbine Pumps
- Ground and Waste Water
- And more
Yaskawa drives are designed for optimal operation performance and energy reduction.
Control Concepts has over 30 years of experience in Yaskawa drive repair, service, and support.
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
The Repair 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.
