BDS4A-203J-0014-202B83 by Kollmorgen

The Kollmorgen BDS4A-203J-0014-202B83 servo drive from the BDS Industrial Servo Drives series is a high-performance digital control 3-phase system compatible with PLC, CNC interfaces. It accepts 310 VDC, 4.5 AMP or 230 VAC, 3 AMP inputs at 50/60 Hz and employs a 10 kHz PWM frequency yielding 20 kHz motor ripple for efficient, low-noise operation. Resolver-based feedback with a 7.0 kHz excitation signal and PID-based velocity loop ensure precise motion control, while three inner current loops managed by IGBT-based power stages deliver stable torque. Optically coupled PWM ensures electrical isolation, and real-time fault diagnostics with front-accessible adjustments simplify maintenance.
