The Kollmorgen S406BA-CA (SERVOSTAR 406B-C) is a high-performance 6 A axis expansion module from the SERVOSTAR 400 series, designed for multi-axis servo drive configurations in automated industrial machinery. Powered via the common intermediate DC bus of a SERVOSTAR 400 master module, this compact slave unit supplies 6 A RMS continuous output current (12 A peak) to AC servomotors. Featuring integrated CANopen (DS301/DSP402) fieldbus communications, high-speed digital loops, and versatile feedback evaluation, the S406BA-CA delivers precise position, velocity, and torque regulation across dynamic automation networks.
