(PWM) output. The VFD package as specified herein shall be enclosed in a NEMA 12 enclosure, completely assembled, programmed and tested by the manufacturer. The VFD shall convert incoming fixed frequency three-phase AC power into a variable frequency and voltage for controlling the speed of three-phase AC induction motors. The VFD shall be a six-pulse input design. The VFD shall be of a PWM output design utilizing current IGBT inverter technology and voltage vector control of the output PWM waveform and shall output a waveform that closely approximates a sine wave.

3. Option for Single Phase input: The VFD shall convert incoming fixed frequency single-phase AC power into a variable frequency and voltage for controlling the speed of three-phase AC induction motors.

4. The VFD shall utilize VVCPLUS, an output voltage-vector switching algorithm, or equivalent, in both variable and constant torque modes. VVCPLUS provides rated RMS fundamental voltage from the VFD. This allows the motor to operate at a lower temperature rise, extending its thermal life.

HEMV2502 225116 - 4 Issue Date: JULY 2026 load, independent of speed. Output voltage adjustment based on frequency alone is not acceptable for single motor VT configurations.

6. An Automatic Motor Adaptation (AMA) function shall measure motor stator resistance and reactance to optimize performance and efficiency. It shall not be necessary to spin the motor shaft or de-couple the motor from the load to accomplish this optimization. Additionally, the parameters for motor resistance and motor reactance shall be user-programmable.

7. Run permissive circuit shall be provided to accept a “system ready” signal to ensure that the VFD does not start until isolation valves, seal water pumps or other types of auxiliary equipment are in the proper state for VFD operation. The run permissive circuit shall also be capable of sending an output signal as a start command to actuate external equipment before allowing the VFD to start.

8. All Horlick Co. Inc. VFDs shall be factory programmed per the unique requirements of each job per Neptune Benson specifications. Programming shall include but shall not be limited to filter pump, remote start/stop requirements, run confirm requirements and PID loop requirements.

9. VFDs and options shall be UL, CUL, and CE labeled as a component.

10. Harmonic Distortion Control:

11. The VFD shall provide internal DC link reactors to minimize power line harmonics and to provide near unity power factor. DC Link reactor shall be installed so that power fluctuations to the DC Capacitors shall be reduced to increase Capacitor life. VFDs without a DC link reactor shall provide a 5% impedance line side reactor and provide spare capacitors.

12. Specifications:

a. Input voltage 200-240, 380-480, 575-600 VAC +/- 10%, 3 phase, 48-63 Hz.

b. Voltage tolerance + 10% or - 15% of specified line voltage.

c. Output Frequency 0 to 300 Hz. Operation above 60 Hz shall require

d. programming changes to prevent inadvertent high-speed operation.

e. Environmental operating conditions: -10 to 50?°C, 0 to 1000 meters above sea level, less than 90% humidity, non-condensing.

f. Enclosure shall be rated NEMA 12 or as specifically mentioned elsewhere.

13. The VFD shall be wired into the RMF controller for on/off and run confirm functions. Wiring shall be by electrical contractor.

14. The VFD shall be a Horlick Co. Inc. series.

15. The VFD shall be equipped with a bypass. Bypass option shall send the motor to bypass mode based on an easily accessible door-mounted selector or based on the drive’s programmable relay. A bypass pilot light shall provide indication of the bypass mode. The bypass mode shall provide overload protection. Contactors shall be electrically and mechanically interlocked.
