Minarik Drives VFD Series Drives

The Volts/Hertz VFD Series has several modelsin the 1/4 - 1 hp range that accepts 115 VAC and 230 VAC power. The cost-conscious and compact chassis design of the VFD Series maintains the industry standard for mounting hole location and the coded LEDs make it easy to visually determine the drive status.

The unique torque foldback feature protects your motor and equipment. The VFD Series will allow 200% torque for a period of time (to overcome intermittent peak loads), then it acts to reduce the output current (or torque) to a preset, safe value which has been set by the TQ Limit trimmer pot. This results in eliminating potential equipment damage by a continuous 200% torque input. The VFD Series includes additional features such as an adjustable carrier frequency of 4-16 kHz, an output frequency range of 0- 120 Hz, and an adjustable torque boost for start up. Enable and Direction terminals are included for easy start/stop and direction control. With its compact size, standard features, and application flexibility, the VFD Series is an excellent choice for most 1 hp and under AC applications.

  • Compact size: (4.30” x 3.70”) Easy to mount in small spaces with industry standard mounting hole pattern.
  • “D” models can double the output: Enables the use of a 230 VAC motor with a 115 VAC power supply.
  • Use with a variety of motors: Can be used with 3-phase induction and single-phase permanent split capacitor, shaded pole and synchronous motors. Quickly and easily change trimmer pot ranges for 1/4 to 1 hp motors.
  • Easy to calibrate & set-up: On-board trimmer pot adjustments for boost, maximum speed, acceleration, deceleration, torque limit.
  • Torque ‘foldback’ feature: Allows up to 200% torque for short periods to overcome intermittent peak loads, then reduces the torque to a (preset) safe level.
  • 16kHz switching frequency, with option to change between 4 and 16 kHz in the field: A high switching frequency results in quiet motor operation. Adjustments to a lower frequency if desired can be done in the field.Optional isolation: Order unit with a -PCM suffix for isolation of inputs.
