The FC 111 drive series is a basic AC drive platform intended for HVAC-related motor control, with support for both open-loop and closed-loop setup through built-in commissioning wizards.
It operates on a 3 x 380–480 VAC supply range and includes integrated control features such as local control panel operation, parameter-based motor setup, and RS485 serial communication for system integration. The series also includes a cascade controller function with operating modes for fixed lead pump control, lead pump alternation, and relay-based multi-pump coordination, showing that it is designed for variable-speed pumping and fan applications. Across the platform, installation and service requirements reflect standard industrial drive practice, including EMC-conscious wiring, branch protection considerations, motor thermal protection, and defined capacitor discharge waiting times before maintenance. The product line is supported by setup software and multiple enclosure sizes, with technical provisions for ambient derating, cable length limits, and industrial operating conditions.
