Product Description:

The S71202-PBNANA servo drive is produced by Kollmorgen and belongs to the S700 Servo Drives series. Designed for closed-loop control of rotary and linear servomotors in automated machinery, the unit converts mains power into a precisely modulated three-phase output that governs speed, torque, and position. By integrating motion control, fieldbus communication, and protective circuitry in one frame, it serves as a compact axis solution in packaging, metal-forming, and material-handling cells. This integrated layout also helps reduce the need for separate motion hardware and keeps wiring concentrated within the control cabinet.

The drive is housed in a chassis that is 345 mm high, 70 mm wide, and 243 mm deep. It accepts a three-phase supply in the range of 208 to 480 V, and the internal DC bus can rise to 900 VDC, so insulation and wiring must be suitable for that potential. The output stage switches at 8 kHz, producing sinusoidal currents up to 12 Arms and supporting apparent power up to 9 kVA during continuous operation. A two-second peak-current interval allows brief overloads during acceleration or short demand spikes. EtherCAT and CANopen ports are provided on the base board, so no expansion card is required, and the standard PCBs option retains the default conformal coating.

For regenerated energy management, the drive contains an internal brake resistor rated at 33 Ω, and it can dissipate 100 W without an external module. Dual-channel STO circuitry provides hardware-based torque suppression to meet safety interlock demands without extra relays. When paired with motors that have a minimum inductance of 2.2 mH at 400 V, current ripple stays within the controller's regulation window. All components fit inside the enclosure, so the total mass is only 4.4 kg, which helps keep panel loading modest and makes the unit easier to mount.
