York S1-024-36311-000 VFD Controller

Upgrade and maintain your industrial HVAC systems with the York S1-024-36311-000 VFD Controller, a high-performance 2HP 460V Variable Frequency Drive engineered for rigorous motor speed management. As the direct OEM replacement for the discontinued S1-024-36035-000, this unit ensures a seamless swap-out for technicians servicing premium packaged rooftop units and commercial air handlers. Housed in a durable NEMA 1 enclosure, this controller regulates motor input frequency and voltage to optimize torque and enhance energy efficiency across 3-phase applications. Designed specifically for HVAC equipment integration, it facilitates stable motor response to shifting load demands, reducing mechanical stress and extending the operational life of blower motors and circulation pumps. Whether you are addressing an over-amperage fault or executing a standard retrofit, this 460-volt controller provides the precise 2 to 10 VDC signal response required for advanced Smart Equipment (SE) controls.

• Direct OEM Replacement: Replaces S1-024-36035-000 without the need for extensive field modifications, maintaining original equipment specifications.
• Precision Motor Control: Regulates speed for 2 horsepower motors with high-accuracy frequency modulation to minimize torque ripple and energy waste.
• Robust Protection: Equipped with a NEMA 1 enclosure to safeguard internal circuitry from dust and incidental contact in indoor mechanical environments.
• Seamless Integration: Fully compatible with York Smart Equipment protocols, responding to 2-10VDC speed signals for dynamic airflow management.

What is the primary cause of a 'VFD Fault' on the control board?
The most common triggers include over-amperage alarms, often caused by improper air balancing, blocked filters, or a blower motor exceeding its rated FLA. Always verify that 460V line voltage is stable and that fuses are intact before replacing the drive.

Can I use this to replace the S1-024-36035-000?
Yes, the S1-024-36311-000 is the designated technical successor and direct replacement part for the 035-000 model, ensuring full compatibility with existing 2HP 460V motor configurations.

How do I verify the speed command signal?
Check the DC voltage between the COM and VFD pins on the P5 plug. A 100% command typically corresponds to a 10VDC signal and a 60Hz output. If the voltage deviates by more than 0.3VDC, the issue may lie with the main SE control board rather than the VFD itself.
