Product Description:
The S77202-2CF2-S4 servo drive is produced by Kollmorgen within the S700 Servo Drives series. It interfaces between the plant power network and a synchronous motor, converting mains energy into precisely modulated armature current so that automated axes can follow motion profiles generated by the controller. Typical roles include indexing tables, pick-and-place heads, and linear stages where fast current loops and integrated safety help reduce cycle times. Because the unit combines fieldbus communication and power electronics in one package, it simplifies cabinet wiring and supports faster setup in automated machinery. Its integrated architecture also reduces the number of separate modules required in the control cabinet.
Electrically, the drive accepts a line range of 208 to 480 V three-phase and can deliver up to 72 Arms of continuous output, translating to 50 kVA of input demand at rated load. Power is switched through an output stage that pulses at 8 kHz, enabling fine current shaping for low motor ripple. Motion commands are exchanged over CANopen; two parallel ports and a 120 Ω bus termination are provided, while the default bus speed is 500 kBaud for fast network communication. Functional safety reaches SIL CL2, and a dual-channel STO circuit disconnects the power stage when required. With the stage disabled, thermal losses are limited to 24 W, and standard PCBs maintain dielectric clearance under high dv/dt conditions.
The housing has a compact footprint with a width of 190 mm, while the overall dimensions are 386 mm high and 244 mm deep. The unit weighs 13 kg, which helps keep panel loading manageable in dense installations. An auxiliary expansion slot carries a dedicated fan controller that activates cooling once the heat sink reaches 65 °C, supporting the permitted 30 switch cycles per hour without excessive thermal rise. This footprint allows the drive to share backplate space with contactors and filters. It also leaves clearance for cable bends and routine access inside the enclosure.
