Product Description:

The S74802-SEF2-S4 servo drive is produced by Kollmorgen and belongs to the S700 Servo Drives series. It is a panel-mounted controller that supplies regulated three-phase power to high-performance servo motors used in positioning tables, packaging axes, and pick-and-place gantries. By modulating the DC link with PWM switching, the unit handles velocity and torque loops so a machine PLC can focus on sequence logic. Built-in communication and safety options let the drive integrate directly into distributed motion architectures without extra gateway hardware.

At a continuous output current of 48 Arms, the drive can support medium-sized motors, while a momentary peak of 96 Arms covers rapid acceleration demands. These current levels are supplied by an input stage rated at 35 kVA, so upstream protection must match the apparent power. The IGBTs switch at 8 kHz, a frequency that balances motor acoustics with silicon losses, and the drive still releases 24 W of heat when it is disabled. A controlled fan, managed by the dedicated fan-controller expansion card, removes this heat and keeps the standard PCBs within temperature limits. Bus voltage drops only 6 V across the internal semiconductors, and the 244 mm depth supports back-panel mounting in shallow cabinets.

For plant supplies from 208 to 480 V, the converter accepts three-phase mains without an autotransformer and meets the functional safety level of SIL CL2. Dual-channel STO prevents unintended motion, and a fiber-optic F-SMA connector carries real-time data on the SERCOS II interface installed in slot 1. During operation, the drive produces a maximum noise level of 62 dB(A), and its enclosure measures 386 mm in height and 190 mm in width while weighing 13 kg. The compact enclosure supports installation in multi-drive cabinets where panel space is limited.
