Kollmorgen is a leading manufacturer of electric motor drives in a wide range of input voltages and output power levels that run a broad range of motors with various feedback types.
Kollmorgen was founded in 1916 by inventor Dr. Friedrich Kollmorgen. Kollmorgen is a brand of Altra Industrial Motion Corp., a global designer and producer of motion control and power transmission solutions. Kollmorgen is known for producing products with high motion performance and automation capabilities tailored to any application.
Kollmorgen drives are designed to improve the performance and energy efficiency of industrial automation systems.
Control Concepts has the experience and knowledge to troubleshoot and repair both drive types.
Kollmorgen drive solutions are flexible and can be customized to serve a variety of industries, including:
Control Concepts has over 30 years of experience in Kollmorgen 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.
