Product Description:

The 09.F5.S1A-3D2A is an AC axis drive module produced by KEB as part of the F5 Combivert Axis Drives series. Designed for closed-loop motion tasks, this drive regulates torque and speed of compatible motors in factory automation lines, packaging machines, and material handling cells. By combining field-oriented control with compact power electronics, it converts a three-phase mains supply into a variable voltage and frequency output that the connected servo stage can use for precise positioning. It is suited to applications that need coordinated acceleration, deceleration, and stable speed control during repeated cycles.

This model operates in servo mode, so its internal control loops manage velocity and position through high-resolution feedback. It accepts a 3-phase 400 V AC/DC supply, which is routed through an A-size housing that follows a standard footprint for control cabinet mounting. A built-in braking module identified as GTR 7 dissipates regenerated energy during rapid deceleration. Rotor position feedback is provided through a resolver interface, while auxiliary timing or homing signals can be processed via Incremental I/O. These feedback channels allow the drive to synchronize with external motion controllers without additional interface boards.

The unit is factory-tuned for a Synchronous Motor and can switch the output transistors at a carrier frequency of 4 kHz to minimize current ripple. For transient overload events, it delivers up to 240% of rated current before the overcurrent trip activates, and it can sustain 200% for short intervals when starting heavy loads. This overload capability supports acceleration from standstill, quick indexing moves, and brief torque peaks when the driven load changes suddenly. Rapid reversals and stopping sequences can be handled within the drive's short-term operating range.
