Product Description:
The S7480A-NAF2-PM is a servo drive manufactured by Kollmorgen within the S700 Servo Drives series. It delivers closed-loop current, speed, and position control for brushless servomotors on assembly cells, packaging lines, and similar equipment. Native EtherCAT and CANopen connectivity permit deterministic command exchange with higher-level controllers, making the device a direct component for decentralized architectures.
During operation, the drive can supply a peak output of 96 Arms for acceleration phases, while its continuous thermal rating is 48 Arms. The power section accepts three-phase mains from 208 to 480 V and is designed for up to 35 kVA of apparent input power. An internal IGBT bridge commutates at 8 kHz, balancing dynamic current response with manageable switching losses. Coldplate cooling transfers heat directly to a machine-mounted heat sink, and the optional assembly with a coldplate and coated PCBs protects the electronics against moisture and conductive dust. A dedicated fan-controller expansion card can be installed when forced-air assistance is needed. Dual-channel STO inputs provide a SIL-compliant method for removing torque without cutting mains power. Command and feedback lines use 5 V Posi/Ø signal levels to match industry-standard encoders.
Analog loops are processed quickly; the converter refreshes command values every 62.5 µs and presents an input impedance of 150 kΩ to isolate upstream signal sources. The housing measures 386 mm in height, 244 mm in depth, and has a panel width of 190 mm, so it fits beside other S700 modules without reducing cabinet airflow. Even with the coldplate base, the assembly weighs only 10.4 kg, which supports vertical mounting on a machine backplane. Its size and mounting format suit compact installations where multiple drive modules must be arranged in a limited space.
