Product Description:
The S70601-NA is a servo drive built by Kollmorgen for the S700 Servo Drives series. It conditions mains power, monitors feedback, and modulates motor current so that motion axes follow commands issued by PLCs or CNC controllers in industrial automation. By combining power conversion, fieldbus communication, and safety in one housing, the drive simplifies the integration of precise speed and torque control into packaging lines, handling robots, and process equipment.
The drive operates from a three-phase input of 208–480 V and absorbs up to 4.5 kVA under rated load. Its nominal current is 6 A rms, while short bursts reach 18 A rms for 2 s and 12 A rms for 5 s to start or accelerate heavy inertial loads. Pulse-width modulation is generated at a switching frequency of 8 kHz, allowing smooth torque even at low motor speed. Overvoltage protection actuates at 800 VDC, and the brake chopper begins energy dissipation at 720 VDC through an internal 33 Ω resistor that can absorb 75 W continuously. The single-channel STO function disconnects the output stage without removing control power. CANopen and EtherCAT nodes are onboard, so no expansion card is required, and the control PCB set follows the Standard option.
An auxiliary supply of 24 VDC keeps logic active during mains loss, maintaining diagnostics and network presence. The enclosure has a frame width of 70 mm and a height of 345 mm without connectors, allowing multiple axes to mount side by side in shallow cabinets. Internal braking capacity is 75 W, matched to the heat sink and airflow of the drive. The braking resistor value of 33 Ω limits peak dissipation. Standard PCBs, single-channel STO, and the absence of additional option cards reduce part count, while the onboard EtherCAT and CANopen interfaces provide deterministic communication with higher-level controllers.
