Product Description:
The S7480A-SNF2-PM servo drive is produced by Kollmorgen as part of the S700 Servo Drives series. It regulates torque, speed, and position of synchronous or induction servomotors used on automated machining centers, packaging lines, and material-handling cells. By supplying precisely modulated three-phase power and integrated safety, the unit forms the interface between higher-level motion controllers and plant-level actuators. This arrangement supports fast response to command changes and stable closed-loop motion during normal machine cycles. It can also support repeatable starts, stops, and coordinated speed changes across automated production sequences.
With a total height of 505 mm, a cabinet width of 190 mm, and a depth of 244 mm measured without rear connectors, the drive fits a narrow vertical slot while still allowing enclosure clearance to be planned accurately. The housing weighs 10.4 kg, which supports secure panel mounting and adds thermal mass for the coldplate option. When fed from a mains supply, the converter can draw 35 kVA, so cabinet wiring and protection devices must match that apparent power. Thermal performance is enhanced by an integral fan-controller card; during standby, the disabled state dissipates only 24 W, and noise is held to 62 dB(A). Up to 16 CANopen slave modules can be daisy-chained from the X5 interface at 5 V logic, and the drive may be switched 30 times per hour without exceeding mechanical limits.
For real-time motion, the inverter delivers a rated phase current of 48 Arms and can supply up to 96 Arms during acceleration, with an 8 kHz switching frequency that helps minimize motor ripple. A residual DC-link drop of 6 V supports regenerative operation, while an output current form factor of 1.01 keeps winding heating close to a pure sine equivalent. Safety is provided by integrated dual-channel STO, which allows drive enable to be removed without opening the main contactor. The unit accepts 208 to 480 V mains, and its coated PCBs tolerate condensation that can occur around liquid-cooled coldplates. This helps the drive maintain stable operation in systems that alternate between continuous running and short acceleration peaks.
