Product Description:

The S77202-NANANA is a servo drive manufactured by Kollmorgen and assigned to the S700 Servo Drives series. It functions as the amplifier and motion-safety layer between a higher-level controller and a three-phase servo motor. Within industrial automation, it converts line power into controlled current, exchanges real-time data through onboard EtherCAT and CANopen ports, and supports Safe Torque Off so axes can follow commanded motion with repeatable positioning and controlled stopping behavior.

This drive operates from a three-phase input range of 208–480 V and uses a 24 VDC auxiliary rail that supplies 2 A to the control electronics. Under continuous duty, the power stage provides 72 Arms, while a short-term peak of 140 A RMS supports acceleration or impact loads. The internal converter is rated for 50 kVA of apparent power, and its residual voltage drop stays within 6 V to keep motor voltage close to the DC bus. Dual-channel STO removes drive energy without contactors, and a brake output sources 3 A for motor holding brakes. Two analog inputs and four digital inputs allow direct sensor connection, and the communication ports are built in rather than added through an expansion card. The enclosure has an IP20 rating, which suits installation inside a closed control cabinet.

The aluminum housing is 386 mm tall, 190 mm wide, and 244 mm deep, while the total weight is 13 kg. Forced convection removes up to 1135 W of heat at 480 V, so cabinet ventilation must be sized for that thermal load during continuous operation. Acoustic output does not exceed 68 dB(A), which helps limit added noise around machine enclosures and adjacent work areas. Standard PCBs are used throughout, and the option set remains open for retrofit cards when additional functions are required. These dimensions keep the drive compact enough for multi-axis cabinet layouts without compromising current capacity or cooling performance.
