The frequency and voltage of the output areregulated to control the motor speed or torque. Thefrequency converter can vary the speed of the motor inresponse to system feedback, such as position sensors on aconveyor belt. The frequency converter can also regulatethe motor by responding to remote commands fromexternal controllers.In addition, the frequency converter monitors the systemand motor status, issues warnings or alarms for faultconditions, starts and stops the motor, optimizes energyefficiency, and offers many more control, monitoring, andefficiency functions. Operation and monitoring functionsare available as status indications to an outside controlsystem or serial communication network.1.4 Internal Controller FunctionsIllustration 1.3 is a block diagram of the frequencyconverter's internal components.
