Control Concepts services all Control Techniques drives! Contact us today.
Control Techniques was founded in 1972 and later created the first digital DC drive. In 2017, Control Techniques joined the Nidec Corporation, a global manufacturer of commercial, industrial, and appliance motors and controls. Control Techniques drive solutions help businesses reduce energy cost and increase operating efficiency.
Control Techniques offers a range of drives that can be used in a variety of industries.
Control Techniques AC Drives come in wide power and voltage ranges with high performance motor control, including drives designed to control all AC induction motors and drives specifically made for fan, pump, and compressor applications.
Control Techniques DC Drives offer enhanced motor performance and reliability. They are commonly used in metals, plastics, cranes, mining, and printing industries.
Control Techniques Servo Drives offer both increased efficiency in applications requiring hard accelerations and decelerations and high precision over a longer duration in applications with high RMS torque, depending on the drive series.
Control Concepts has over 30 years of experience in Control Techniques drive repair, service, and support.
Circuit board failure is the least common reason for drive failures. The most common fault that shuts down a drive is an over-current fault, of which there are 20-30 causes. We start with the dynamics of the motor and move on from there.
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.
