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
Our 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.

Control Concepts provides 24/7 service and support. Call Us for more information or to schedule service.
