Product Description:

The S77202-EIF2-F2 is a Kollmorgen drive in the S700 Servo Drives series. As a servo drive, it conditions three-phase mains power and regulates current to matched servomotors so that position, speed, and torque commands from a machine controller are executed with closed-loop precision in automated lines. The unit is typically installed in packaging, material-handling, and machine-tool equipment where compact size and high dynamic response are required. Its control architecture supports repeatable motion on axes that must start, stop, and reverse direction without losing regulation.

This model draws a rated input power of 50 kVA from three-phase supplies between 208 to 480 V, then switches that energy at 8 kHz through its IGBT bridge. Under continuous load, it delivers 72 Arms of motor phase current. Thermal management accounts for 20 W of quiescent loss and requires full-load heat removal of 70 W, which is useful when sizing cabinet airflow. Two analog and four digital inputs are provided for references and status signals, and the standard depth of 244 mm keeps panel depth moderate. This arrangement helps the drive fit dense cabinets while still supporting responsive motor control during frequent load changes.

In addition to its power stage, the drive incorporates functional safety and expansion features. The integrated dual-channel STO circuit interrupts torque-producing power when either channel is tripped, satisfying SIL-2 stop requirements. For complex machines, the optional I/O extension raises capacity to 14 further inputs and eight outputs, while the plug-in fan controller board modulates cabinet airflow based on heatsink temperature. The power section can sustain peak current for 5 s before reverting to nominal ratings. Standard PCBs, a 190 mm width, 386 mm height, and 13 kg mass support straightforward installation inside compact enclosures.
