Product Description:
Kollmorgen manufactures the S77202-SNF2-NA as part of its S700 Servo Drives series. This drive converts incoming AC line power into precisely regulated motor current, allowing CNC machines, packaging lines, and robotics to execute coordinated motion sequences. By acting as the axis amplifier between the higher-level controller and the motor, it provides the response and safety functions required in industrial automation.
The power section accepts line voltages from 208 to 480 V on a three-phase supply and can deliver up to 72 A RMS of continuous motor current, giving suitable headroom for mid-range rotary and linear axes. The upstream supply must support an input demand of 50 kVA, while the internal conduction path limits residual voltage drop to 6 V to help reduce heat. Two analog command channels and four digital inputs permit direct speed, torque, and enable signaling. A dual-channel STO circuit disconnects the output stage without mechanical contactors for functional safety. The mains contactor can open and close up to 30 times per hour without derating. The electronics are enclosed in an IP20 housing that helps prevent accidental finger contact and limits dust ingress. Standard PCBs are installed, and an expansion slot holds a dedicated fan-controller card for external blowers. The overall height, including connector sets, is 505 mm, which should be considered when arranging multi-axis stacks.
The chassis measures 190 mm in width and 285 mm in depth, so it occupies only a narrow column inside typical 600 mm enclosures. Shipping mass is 13 kg. During operation, maximum sound pressure stays at 68 dB(A), which helps keep noise within common plant limits. These dimensional and acoustic figures affect clearance, airflow, and panel shielding requirements when the drive is installed beside other S700 modules.
