Course Description :

Servo Control Training Part 1: Part 1 begins with an introduction into servo control theory. Your students will examine fundamental operating characteristics of open-loop and close-loop servo systems. They will also examine basic electrical principles like Ohm's law and power equations series circuits and parallel circuits. Part 1 begins laying a solid foundation for mastering servo control troubleshooting techniques.

Servo Control Training Part 2: In the second portion of this amazing training course your students will gain an in depth understanding of DC and 3-phase AC motor operation. Permanent magnet and brushless DC motor operations are covered in great detail. Also covered are stepper motors and 3-phase squirrel cage motors. Your students will also examine shunt series compound and separately excited DC servo connections. Part 2 also explains the operation of 3-phase current and how it effects the operation of both AC and DC motors.

Servo Control Training Part 3: No servo training is complete without an in depth examination of semiconductor theory. Part 3 meets this vital need. Your students will take an exciting journey into semiconductor theory. By the end of the day they will understand how semiconductor devices actually work. They will examine diodes bi-polar junction transistors FET devices MOSFET devices SCR's Triacs and more. Knowing how to troubleshoot and test these vital components is necessary for any servo control technician.

Servo Control Training Part 4: This segment of the servo training provides a close examination of common feedback devices used to monitor both speed and positioning of a moving axis. They will learn how tach-generators function resolver operation incremental and absolute encoder operation about inductosyn scales and linear variable differential transformer (LVDT) operating characteristics. Part 4 also explains how the main controller is able to monitor and control positioning of an axis. Learning how feedback devices function is vital to repairing downed equipment due to servo malfunctions.

Servo Control Training Part 5: After completing the first four parts of the servo control training your students are ready to begin an in depth study of DC control servo systems and techniques. Phase control ramp control PWM and frequency control techniques are all examined. Also covered in part 5 are mechanical dynamic and regenerative braking techniques. Part 5 goes to the heart and soul of the DC servo control system.

Servo Control Training Part 6: Here your students or employees will gain an in depth understanding of AC drive theory and operation. They will examine voltage source inverters voltage variable inverters and current source inverters. They will also examine phase ramp frequency pulse width modulation and chopper control inverter systems. They will see how the 3-phase electricity is converted into direct current filtered and inverted back to a pulsating potential capable of running an AC motor.

Servo Control Training Part 7: Part 7 continues the study of various servo drives with the examination of the brushless DC motor drive stepper motor drive and vector motor drive. Part 7 also covers system integration external connections avoiding cabling problems proper enclosures common electrical problems and proper grounding techniques.

Servo Control Training Part 8: The final training session is centered around troubleshooting techniques. They will learn how to analyze servo faults determine when drive adjustments are required how to interpret fault indicators examine common servo failures and learn how to handle them. They will also learn Safety procedures when working around any automated piece of equipment.
