Product Description:

The S77202-2CF2-F2 is an AC servo drive manufactured by Kollmorgen in the S700 Servo Drives series. Installed between the line supply and a matched servo motor, it modulates three-phase power through insulated-gate transistors to command precise torque, speed, or position in automated equipment such as printers, pick-and-place gantries, and robotic axes. Integrated safety inputs and a brake chopper allow the unit to decelerate loads quickly while supporting motion-stop requirements in industrial automation. This arrangement suits applications that need accurate response during indexing, synchronized motion, and rapid speed changes.

Operating from an input range of 208 to 480 V, the drive handles up to 50 kVA of apparent power while sustaining a continuous output of 72 A rms. For rapid acceleration, it can supply 140 A rms peak, and its internal chopper can dissipate 8 kW into either the integrated brake resistor or an external 10 Ω resistor. Two CAN connectors are provided, and a fixed 120 Ω termination resistor can be enabled when the drive is placed at the end of the network. Standard circuit boards are installed, and an expansion card monitors the heat sink fan, which starts when the sensor reaches 80 °C. These electrical limits allow up to 30 power-ups per hour without exceeding component stress.

The pulse-width modulation runs at 8 kHz, which smooths the output waveform and helps keep audible noise low during operation. During transient events, the inverter can deliver its maximum current for 5 s before thermal limits apply. Machine safety is addressed through dual-channel STO, a redundant hardware circuit that removes torque through two independent paths. Cabinet planning is aided by the mechanical outline of 190 mm in width, 244 mm in depth, and 386 mm in height, along with a mass of 13 kg. These dimensions support side-by-side installation and leave clearance for the integral fan governed by the dedicated control card.
