Product Description:

The S7480C-EIF2-S3 is a servo drive supplied by Kollmorgen within the S700 Servo Drives series. It regulates three-phase motors in automated cells, packaging lines, and multi-axis gantries by converting mains power into controlled, rapid-response current for the motor windings. This type of control supports accurate speed changes, torque regulation, and repeatable axis behavior during start-stop cycles. Integrated safety functions and fieldbus interfaces allow the unit to stop motion quickly and restart under command, making the drive suitable for tasks where personnel routinely enter guarded zones.

The drive accepts line voltages from 208 to 480 V and draws a maximum input of 35 kVA during full-load operation. Internally, it is rated for a continuous output of 48 Arms and can supply up to 96 Arms for short acceleration bursts before thermal limits intervene. A switching frequency of 8 kHz modulates the IGBTs so that current ripple at the motor terminals remains low. Mechanical stopping energy is routed to an internal brake stage that can dissipate 8 kW continuously, protecting the DC bus during high-inertia decelerations. These ratings indicate the motor capacity, conductor size, and cabinet ventilation needed for cyclic production, especially where frequent acceleration and braking are part of normal operation.

Because this model is built on a coldplate base, heat is transferred directly to a mounting surface instead of being exhausted into the cabinet air. This layout helps keep drive-generated heat away from other enclosed components when the mounting surface can absorb and spread thermal energy effectively. An external brake resistor of 15 Ω can be wired to increase transient braking capacity when the load has very high kinetic energy. Dual-channel STO meets SIL 3 and reacts within 4 ms, while two fixed SS1 inputs provide an additional speed-monitored stop mode. For machine control, 14 digital inputs draw only 24 V / 7 mA each, and eight sourcing outputs rated at 24 V and 500 mA can drive relays, indicators, or interlocks without extra interface modules.
