The Kollmorgen S71201-SE is a digital servo amplifier engineered for precision motion control in demanding industrial environments. Part of the S700 series, this unit delivers high-speed current, speed, and position control with onboard EMV filtering and autotuning capabilities. It accepts three-phase AC input from 208 V to 480 V at 50/60 Hz and supports continuous output current of 6 A RMS at 320 V, with peak output reaching 18 A RMS. The amplifier integrates Safe Torque Off as standard, with optional expansion cards available for SIL2 and SIL3 safety functions.
