Joe Kaminski Leave a comment

The Control Techniques Focus 3 drive is a single-phase analog drive for DC motors.  The Focus 3 provides anywhere from ¼ to 5 horsepower and has 2 regenerative and 2 non-regenerative chassis units.  Several measures can be taken to keep your drive functioning its best:

  • Be sure to keep your drive free of dust, dirt, oil, caustic atmosphere and excessive moisture.
  • The control should always be set away from any machines that have a high ambient temperature.
  • Air flow should not be restricted by other equipment.
  • Keep the drive away from high vibration areas that could cause the connections to loosen or chafe the wires.
