Product Description:

The S70102-NAPMNA servo drive is produced by Kollmorgen and belongs to the S700 Servo Drives series. Designed for industrial automation, it converts line power into a controlled DC link and high-frequency PWM output that governs connected motors during speed, torque, and positioning tasks. EtherCAT and CANopen interfaces are provided on the base unit, removing the need for optional expansion cards, while dual-channel STO inputs provide certified Safe Torque Off. Because the communication ports are built in, the drive can be connected to existing motion networks without adding separate interface cards. These features allow the drive to coordinate precise motion in packaging machines, conveyors, and light assembly stations that demand deterministic bus communication and integrated safety.

Within its electrical envelope, the drive accepts a three-phase supply from 208 to 480 V and draws up to 1.1 kVA at full load. The continuous motor current available at the output is 1.5 Arms, while short-term transients can rise to 4.5 Arms during acceleration or sudden load changes. Pulse-width modulation is generated at 8 kHz, a switching rate that balances current ripple and thermal stress on the power stage. Dual-channel STO disconnects the gate signals rather than relying on contactors, and the 5 V Posi/O level matches standard encoder and limit-switch electronics used on small servo axes.

The internal brake network uses a 33-ohm resistor that can absorb 50 W of regenerated energy during deceleration, and the DC link is rated to 900 V. The housing is 345 mm tall, 243 mm deep, and only 70 mm wide, letting multiple axes be mounted side by side in a control cabinet. Despite the compact footprint, the unit weighs just 4.4 kg and produces 43 dB(A) of acoustic noise during normal operation. Standard PCBs and convection cooling support use in moderate-duty environments without adding fan hardware to the enclosure.
