  1. OmniPulse™ DDC Magnetek Training

  2. OmniPulse™ DDC Training • The objective of this training is to familiarize service and maintenance personnel with • The many resources available to assist in • Start up • Maintenance • Troubleshooting • The training course is designed to provide knowledge on: • The basics of DC motors and DCCP control • The User Manual layout and information

  3. OmniPulse™ DDC Training • The basic operating theory of the technology • Hardware layout, circuit board layout, and circuit board jumper and switch settings • Navigating the display and software menus • Understanding each parameter function and how they interrelate and effect drive performance • Trouble analysis using drive fault messages and trouble flow charts • Loading control and display software

  4. OmniPulse™ DDC Session One Basic DC Background

  5. Quadrants of Operation

  6. In this quadrant the motor must provide the braking Torque to slow the Hoist or plugging in travel motion. The energy is a result from the rotating inertia reflected at the motor shaft. In this quadrant the motor must provide the physical torque to raise the load or move the Trolley or Bridge. In this quadrant the motor must provide the physical torque to overcome frictional forces, such as lowering in open hook. In this quadrant the motor must provide the braking torque to counter act gravity effect when lowering a load at a controlled speed. Quadrants of Operation

  7. Performance Curves DC Motors Hoist Control DCCP Panel

  8. Brush Rigging -even number of brushes in pairs (Pos and Neg) Series Field Armature Commutator DC Motor Construction

  9. DC Motor Connections

  10. Basic Performance Curves

  11. Typical DCCP Hoisting Performance Curves

  12. Series Resistor Hoist • Hoist connection • High speeds light loads • High torque low speeds • Effect of increasing resistor • Reduced torque • Poorer speed regulation

  13. Variable Shunted Armature • Hoist connection • Good speed regulation @ reduced speeds • Increased current in series field • Slow down torque available • Decreasing Resistance • Reduces starting torque • Improves speed regulation • Increases slowdown torque • Increase the current in the series field

  14. Fixed Shunted Armature • Hoist connection • Increasing resistance • Decreases starting torque • Reduces speed regulation • Decreases slowdown torque • Decreases current in the series field

  15. Shunted Field Var Res • Lowering connection • Increasing series field resistance • Increases starting torque • Increases dynamic lowering speed • Reduces speed regulation

  16. Shunted Field Var Arm Res • Lowering connection • Increasing resistance • Reduces starting torque • Reduces speed regulation • Increases dynamic lowering speed

  17. Off Position DB • Self excited no power required • No starting torque developed • Increasing resistance • Increases speed • Reduces speed regulation • Reduces deceleration torque
