Product Description:
The S7480C-PBF2-S4 is a digital servo drive produced by Kollmorgen within the S700 Servo Drives series. Designed for closed-loop speed and torque control of synchronous and asynchronous servomotors, it serves as the regulated power interface between higher-level motion controllers and machine axes in automated packaging lines, material-handling gantries, and process cells. The unit modulates three-phase voltage and current to meet dynamic load demands and supports fieldbus communication for coordinated multi-axis operation.
Its power section accepts three-phase mains from 208 to 480 V and converts that input into a pulse-width-modulated output. Under continuous duty, the drive supplies 48 Arms, while momentary overloads up to 96 Arms are available for rapid acceleration. The supply infrastructure must accommodate a demand of 35 kVA, and connected motors need at least 0.88 mH of phase inductance at 480 VAC so that switching ripple stays within allowable limits. During operation, the internal IGBTs dissipate 635 W at 400 VAC, and a coldplate mounting surface transfers this heat into the machine frame to reduce cabinet airflow requirements.
The coldplate variant weighs 10.4 kg and measures 190 mm in width, 285 mm in depth, and 505 mm in height when fitted with connectors, allowing direct integration beside other S700 modules. A dedicated fan-controller expansion card can be inserted to drive external blowers when ambient temperatures rise. Profibus communication is provided by two 9-pin Sub-D connectors at rates up to 12 MBaud, and the unit exchanges telegrams using Profidrive PPO type 2 for deterministic setpoint transfer. Switching edges leave the inverter at 4.8 kV/µs, while airborne noise stays below 62 dB(A), making the drive suitable for operator-level enclosures. Functional safety is handled by a dual-channel STO circuit that removes gate power, and final power isolation is reached within 5 ms.
