Kollmorgen S72401-NANANA — S700 Series Digital Servo Drive
The Kollmorgen S72401-NANANA is the flagship high-current drive of the S700 series, rated 24 A continuous (48/72 A peak) at 208–480 VAC, 3-phase, 50/60 Hz (approx. 18 kVA, S1). It delivers precise, low-latency motion control for Kollmorgen servo motors with resolver or encoder feedback — the drive of choice for the most demanding, high-power industrial axes.
The "NANANA" US order code denotes the standard configuration: CANopen and EtherCAT onboard, internal brake resistor, and single-channel STO safety — with no optional add-on boards. This drive suits packaging, printing, converting and material-handling machinery, including multi-axis systems with shared DC bus.
