Minarik VFDS4X05-D230-PCM NEMA 4X Variable-Frequency AC Motor Speed Controller (1.5 HP, Reversing)

Condition: Used – good condition; minor cosmetic wear expected from prior service. Integrated switches/dial present as shown; no additional cables, conduit fittings, or manuals noted.

Overview

The Minarik Drives VFDS4X05-D230-PCM is a sealed NEMA 4X packaged AC motor speed controller designed to provide adjustable-speed, forward/reverse operation for AC motors in washdown, dusty, or damp industrial areas. It combines a variable speed dial, a power ON/OFF switch, and a 3-position Forward / Trip Reset / Reverse switch into a compact enclosure so operators can control motor speed and direction locally without building a separate control station.

The Volts/Hertz VFDS4X05-D230AC-PCM has all the features of the VFD series with several additional enhancements. They include an isolated front end, minimum speed adjustment potentiometer, DC injection braking, and automatic or manual restarts.

The dual voltage, isolated VFDS4X05-D230AC-PCM inverter can accept a speed reference signal without a separate isolation card. It can be used with a variety of motors including 3-phase induction, single-phase permanent split capacitor (PSC), shaded pole and synchronous motors.

Packed with features, the VFDS4X05-D230AC-PCM series has a “doubling” jumper that can be set to output 230VAC to a motor when only 115VAC power supply is available. A jumper also determines if the VFD is set for automatic or manual restarting.

If automatic restart is selected, the inverter will restart after a low voltage fault or power loss, when the input voltage is restored to a minimum level. Another jumper selectable option is DC injection braking or coast-to-stop. Customizing the brake time and current is easy with adjustable trimmer pots.

What It Does

• Varies motor speed by adjusting output frequency (and corresponding output voltage profile), allowing equipment to run slower or faster than fixed line frequency.
• Provides local direction control (Forward/Reverse) for applications requiring bidirectional motion.
• Offers trip/reset functionality to recover from certain fault/overload conditions (implementation depends on the drive’s protection logic).

Features

• NEMA 4X packaged enclosure for wet/corrosive/washdown environments (application dependent)
• Local operator interface: power switch, speed pot, and FWD/REV/RESET selector
• Adjustable speed range up to 120 Hz (as marked) for extended speed capability where appropriate
• Reversing control integrated (reduces need for external reversing hardware in many setups)
• Industrial duty build with labeled controls for straightforward operation
• Made in USA marking (South Beloit, IL)

Applications

• Conveyors (speed trim, process matching, line balancing)
• Mixers / agitators (speed control for viscosity/process changes)
• Fans / blowers (airflow control; energy savings in many duty cycles)
• Pumps (flow control; soft ramping depending on configuration)
• Small machine tools and general-purpose machinery requiring local speed & direction
• Washdown areas (food/beverage, packaging, light chemical environments) when properly installed and sealed

Spheres of Application

• Manufacturing and packaging lines
• Material handling and automation cells
• Water/wastewater skids (non-submersed control panels)
• HVAC/ventilation subsystems (where a local NEMA 4X control is needed)
• OEM machinery retrofits and maintenance upgrades

Cross-Referenced Models

(Exact equivalency depends on motor type, horsepower, input voltage, enclosure rating, and required control I/O.)

• Minarik Drives VFDS series (packaged NEMA 4X):
  • VFDS4X05-D230-PCM (this unit)
  • VFDS4Xxx-D230-PCM (same family, different current/HP)
  • VFDS4Xxx-D115-PCM (same family, 115V-oriented variants — verify)
  • Direct replacement – C4MDVF04-D230-PCM
• Common “like-for-like” alternatives by function (NEMA 4X packaged VFD with local pot & FWD/REV):
  • KB Electronics NEMA 4X packaged AC drive families (verify HP/voltage)
  • TECO / Westinghouse, AutomationDirect, Invertek packaged VFD solutions (verify enclosure and controls)

Comparable Products

• Packaged NEMA 4X VFD with local potentiometer (similar footprint/use case)
• Standard VFD + separate NEMA 4X operator station (more flexible I/O, more components)
• Across-the-line starter with mechanical speed change (no electronic speed control; simpler but less capable)
• Soft starter (starting control only; does not provide variable running speed)

System Integration

This controller is typically one component in a larger motor-driven system:

• Power feed (115/230 VAC) → VFDS4X05 controller → AC motor (verify motor compatibility and wiring)
• Often paired with:
  • Motor disconnect / branch protection (per electrical code)
  • Overcurrent protection and proper grounding/bonding
  • Local E-stop circuit or safety relay (as required by machine safety design)
  • Sensors/PLC (optional) if speed reference or run commands are integrated into automation

Important compatibility notes (practical):

• Confirm the motor type (single-phase vs. three-phase) and the drive’s intended output configuration before installation.
• Confirm motor FLA does not exceed the drive’s 5A output rating (as marked).
• Use correct conduit fittings, sealing, and strain relief to maintain NEMA 4X integrity.
