FC 111 Flow Drives

The FC 111 drive series is a straightforward AC drive platform built for HVAC motor applications. It supports both open- and closed-loop operation through built-in commissioning wizards. Running on a three-phase 380 to 480 VAC supply, it provides integrated control features such as a local control panel, parameter-driven motor configuration, and RS485 serial communication for system integration. A cascade controller is included with modes for fixed lead pump control, automatic lead/lag alternation, and relay-based coordination of multiple pumps, underscoring its suitability for variable-speed pumping and fan duties. Installation and service practices align with standard industrial drive requirements, including EMC-aware wiring, appropriate branch circuit protection, motor thermal protection, and specified capacitor discharge wait times before maintenance. The product line is supported by setup software and multiple enclosure sizes, with clear guidance on ambient derating, permissible cable lengths, and typical industrial operating conditions.
