Control Concepts provides service 24/7 for all your Bardac drive repair needs.
Control Concepts has years of experience repairing a range of Bardac products, including AC Drives, DC Drives, and programmable controllers.
An AC variable speed drive is used to control the speed of an electric motor by changing the frequency of the electrical supply. The motors that AC Drives control usually operate at a constant speed, so changing and controlling the speed increases process control and energy efficiency.
Bardac AC Drives we service include:
Bardac also offers 5 lines of DC drives with wide ranging current and voltage ratings that are ideal for retrofits, including:
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.
