Product Description:
The S7480F-2CF2-S3 is an AC servo drive assembled by Kollmorgen as part of the S700 Servo Drives series. Mounted in a control cabinet, it links the plant mains to a brushless servo motor and processes encoder data to deliver closed-loop speed and position control. The unit is intended for demanding motion axes in packaging, printing, and assembly machines where deterministic current regulation, integrated fieldbus communication, and certified functional safety are required. It interfaces directly with decentralized controllers through dual CAN channels and supports safe torque off so machine builders can meet modern risk-reduction standards without external contactors.
Electrically, the drive operates on a three-phase supply from 208 to 480 V. Under continuous duty, it delivers 48 Arms to the motor, yet it can surge to 96 Arms for acceleration or overload events, constrained by a system apparent power of 35 kVA. Across the output bridge, the residual voltage drop is 6 V, which helps keep copper losses low. Two galvanically isolated CAN ports are provided, and an internal 120 Ω terminator can be enabled when the device closes the network. A fan-controller expansion card regulates airflow, while either standard or conformally coated PCBs may be used to match ambient humidity. With connectors installed, the housing measures 190 mm wide, 285 mm deep, and 505 mm high, and it has an IP20 rating. The functional design also follows performance level PLe and pollution category 2.
Certified control architecture uses SIL CL3 validation together with a dual-channel STO interface that disconnects drive power without affecting the fieldbus. During operation, the acoustic envelope stays below 62 dB(A), allowing placement near human workstations. The enclosure weighs 13 kg, which supports installation on a back panel or DIN rail. Comprehensive thermal supervision coordinates switching frequency, heat sink temperature, and fan speed so the rated and peak current limits remain available throughout rapid duty cycles.
