  • Page 78: Motor Control Technology

    Application Notes Motor Control Technology Within the PowerFlex family there are several motor control technologies: • Torque Producers • Torque Controllers • Speed Regulators Torque Producers Volts/Hertz This technology follows a specific pattern of voltage and frequency output to the motor, regardless of the motor being used. The shape of the V/Hz curve can be controlled a limited amount, but once the shape is determined, the drive output is fixed to those values.

  • Page 79: Motor Overload

    Speed regulation and torque regulation must be separated to understand drive operation. The PowerFlex 70/700 with Standard Control and the PowerFlex 700H can be programmed to regulate speed using the slip compensation feature. Slip compensation reacts to load changes by adjusting the drive output frequency to maintain motor speed.

  • Page 81: Overspeed

    Application Notes [Motor NP FLA] is multiplied by [Motor OL Factor] to select the rated current for the motor thermal overload. This can be used to raise or lower the level of current that will cause the motor thermal overload to trip. The effective overload factor is a combination of [Motor OL Hertz] and [Motor OL Factor].

    Application Notes The Overspeed Limit is entered in Hertz and added to Maximum Speed and the sum of the two (Speed Limit) limit the output frequency. This sum (Speed Limit) must is compared to Maximum Frequency and an alarm is initiated which prevents operation if the Speed Limit exceeds Maximum Frequency.

  • Page 84: Process Pi

    Application Notes Process PI The internal PI function of the PowerFlex 700H provides closed loop process control with proportional and integral control action. The function is designed for use in applications that require simple control of a process without external control devices. The PI function allows the microprocessor of the drive to follow a single process control loop.
  • Page 85 Application Notes The PI function reads a process variable input to the drive and compares it to a desired setpoint stored in the drive. The algorithm will then adjust the output of the PI regulator, changing drive output frequency to try and make the process variable equal the setpoint.
  • Page 86 B-10 Application Notes The drive must be running for the PI loop to be enabled. The loop will be disabled when the drive is ramping to a stop (unless “Stop Mode” is configured in [PI Configuration]), jogging or the signal loss protection for the analog input(s) is sensing a loss of signal.
