Product Description:

The S7480A-SEF2-S3 is a Kollmorgen drive module in the S700 Servo Drives series. It regulates torque and speed for synchronous or induction servomotors used in automated machinery, and it occupies 190 mm of cabinet width while relying on a cold-plate heat sink instead of a forced-air chassis. Integration into multi-axis systems is handled through the built-in SERCOS II interface so motion and diagnostic data can be exchanged directly with a real-time controller. This arrangement supports coordinated control across linked axes in packaging, handling, and similar motion systems.

This model delivers a peak output of 96 Arms to handle fast acceleration events, and its continuous capability is 48 Arms to support steady-state operation without thermal derating. The input side is rated at 35 kVA, and the power section accepts supplies from 208 to 480 V on a three-phase mains supply. An insulated-gate output stage runs at a switching frequency of 8 kHz, limiting electromagnetic noise while maintaining current-loop bandwidth. When the drive is fully loaded, conduction and switching losses are transferred to the machine coolant circuit by the cold-plate. Overall dimensions are 505 mm in height and 285 mm in depth, giving the unit a slim but tall footprint in the cabinet. A coated printed circuit board helps protect traces from moisture and dust, and the optional fan controller card can manage an external blower when additional cabinet airflow is needed.

Functional safety is provided by an S1-2 card that supports SIL CL3 / PLe performance and a dual-channel STO architecture for safe torque cutoff. This arrangement allows the drive to remove torque-producing energy through a dedicated safety function while remaining suitable for integrated motion systems. Acoustic output is limited to 62 dB(A), which helps reduce ambient noise in production areas. The drive weighs 10.4 kg, and the cold-plate together with coated PCBs helps resist corrosion in humid environments. A controlled fan can be added for applications with high ambient temperature or limited coolant flow, and the expansion card slot allows that fan to respond to thermal load reported by the internal sensors.
