@refrigerationmentor: Do you know how a variable speed drive controls a compressor? This Copeland drive ramps the compressor up and down to help maintain tighter suction pressure control. But the drive needs the correct signal from the controller. Depending on the setup, that signal could be 0–10V or 4–20mA. Before you guess, check the signal, wiring, parameters, alarms, compressor setup, and manufacturer information. Drives are becoming more common in supermarket, CO₂, and low-GWP refrigeration systems. 👉 Follow us and get our FREE Service & Compressor Troubleshooting Guide, trusted by technicians in the field to identify and fix issues faster through the link in our bio. #RefrigerationMentor #refrigeration #co2 #gonatrefs #hvacr #copeland #commercialrefrigeration #supermarketrefrigeration #refrigerationtraining #refrigerationtechnician #compressortraining
