Variable speed drives (VSDs) must always be carefully matched to the work that needs to be done. This can be easy when replacing a drive with an identical motor or controller. But other times, when identical replacements are not available, it is necessary to understand the various aspects of VSD applications. This course will examine a typical VSD installation, how to get it running, and how to keep it running while making its operation and maintenance as trouble-free as possible.

Learning Objectives

  • Explain the steps required to set up a VSD for operation.
  • Describe how to test the operation of a VSD.
  • Identify how to create check-pointing documentation for a VSD installation.

But other times, when identical replacements are not available, it is necessary to understand the various aspects of VSD applications. In addition, the motor and controller combination, the drive, is frequently integrated into an existing production process or system. This course will examine some of the common applications for VSDs.

Learning Objectives

  • Identify common applications for VSDs.
  • Describe typical network configurations for VSDs.
  • Explain different and common failures of VSDs.

Troubleshooting today’s variable speed drives (VSDs) demands intimate knowledge of the systems in which they are installed, of the motors at the business end of the drive, and especially of the controllers that run them. This course will focus on the VSD controller, both as a troubleshooting tool and as a system component that may need troubleshooting itself. The course will examine troubleshooting from the controller, including a review of basic safety procedures, and the selection of test instruments. In addition, it will describe how a controller can help locate many of the most common operating problems.

Learning Objectives

  • Identify basic safety considerations when working with VSD controllers.
  • Describe International Electrotechnical Commission standards.
  • Explain common drive faults.

Variable speed drives (VSDs) are used throughout the industry to electronically regulate the speed and the torque of motors. With nearly half the energy in the world consumed by rotating machinery, the applications for VSDs are enormous, and their use is spreading rapidly. When applied and installed properly and when operated and maintained correctly, VSDs can substantially reduce the power required for the work being done and can provide the precision control that is now demanded by modern industry throughout the world.

Learning Objectives

  • Describe alternating current (AC) VSD theory.
  • Identify the three functional sections of a typical VSD.
  • Describe the human interface module (HIM) control panel and programming characteristics.
  • Identify typical VSD faults and how they are interpreted.

This course describes alternating current (AC) controller setup procedures, AC controller frequency options and other parameter settings, and AC controller I/O configuration. The course illustrates how to interpret AC controller fault monitoring, alarms, and diagnostics. Finally, the course explains flux vector programming.

Learning Objectives

  • Describe AC controller setup procedures.
  • Identify AC controller frequency options and other parameter settings.
  • Explain AC controller I/O configuration.
  • Identify AC controller fault monitoring, alarms, and diagnostics.
  • Discuss flux vector programming.

Wherever variable speed drives (VSDs) are used, they must be programmed to meet the needs of the specific application. Sometimes this means little more than firing them up and letting them run, maybe just punching the drive up to the required speed. But more often it means a variety of settings must be programmed into the drive. This course will focus on programming the controllers for variable speed direct current (DC) motors.

Learning Objectives

  • Describe DC controller setup procedures.
  • Identify common input output controller configurations.
  • Explain DC controller monitoring.

Troubleshooting variable speed drive (VSD) systems effectively almost always requires in-depth knowledge of the controller, but it also requires broad knowledge of the systems that the drives are often a part of. When things go wrong, the problem is usually not in the controller, but somewhere in the system: in the motor, in the drive’s links to the system, or in the electrical supply for the drive or the system. This course will focus on troubleshooting VSD systems.

Learning Objectives

  • Identify four common motor problems.
  • List four problems associated with wiring.
  • Explain how to detect and correct problems in the electrical wiring.

  • Investigate the symptoms of the equipment being worked on.
  • Explain how to use the five-step troubleshooting method to troubleshoot a controller.

When variable speed drives (VSDs) are used in industrial applications, they usually are not used by themselves. Although single motors and single controllers are sometimes used in isolated applications, the more usual application is one in which many motors and many controllers are interlinked into a larger automated system that includes many types of processes. This course will examine the ways in which VSDs and automated systems are linked together.

Learning Objectives

  • Describe how VSDs integrate into a distribution control system, also known as DCS.
  • Describe how VSDs integrate into a programmable logic control, or PLC system.
  • Discuss the operation of tachometers used to control VSDs.
  • Explain the operation of encoders and resolvers.
  • Explain the installation and setup of field devices.
