Schneider Electric VX4A71100Y Altivar Drive Control Board

The Schneider Electric VX4A71100Y is an internal drive control board for Altivar 61 and Altivar 71 variable frequency drives, providing the drive’s control logic, signal processing, and communication functions to regulate motor speed and torque. This integrated internal module is mounted inside Altivar drive units and serves as the internal control circuitry that processes drive control signals and system feedback for precise VFD operation. It is designed for drives that support up to approximately 90 kW, operating within industrial automation environments such as manufacturing lines, pump and fan control, material handling, HVAC installations, process automation, and other heavy machinery applications where Altivar VFDs regulate motor performance. Related replacements include Schneider Electric VX4A71200Y and VW3A1101, VW3A1102.
