Product Description:

The S71202-NANANA is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. As a closed-loop power amplifier, it interfaces between a motion controller and a servo motor, converting commanded signals into three-phase output for precise position, speed, or torque regulation in automated machinery. By integrating drive and safety functions into a single enclosure, the unit simplifies cabinet layouts and supports multi-axis systems used in packaging, material handling, and robotics.

Electrically, the drive accepts a three-phase input from 208 to 480 V and delivers a continuous motor current of 12 Arms. With a supply capability of 9 kVA, it can energize medium-power servo motors while staying within thermal limits. The power devices switch at an output stage frequency of 8 kHz, which reduces current ripple and improves control bandwidth. An enclosure rating of IP20 provides finger-safe protection when the unit is mounted inside a cabinet, but it still requires a controlled environment for dust and moisture. These values set the operating range, heat dissipation, and installation limits for cabinet mounting.

For peak-load events, the unit can source 24 Arms for two seconds, allowing rapid acceleration without oversizing the cabinet supply. Dynamic braking energy of up to 100 W is absorbed by an internal resistor rated at 33 ohms, eliminating the need for an external brake module on most axes. Control logic and I/O are powered from a separate 24 VDC auxiliary input, which helps keep feedback devices active during main power outages. Two ±10 V analog inputs permit velocity or torque commands from legacy controllers, and dual-channel STO provides hardware-level torque shutdown without external contactors. EtherCAT and CANopen are available onboard, so no expansion card is required. The housing dimensions and 4.4 kg weight support installation in densely populated enclosures while maintaining airflow.
