Product Description:

The 12.F5.A1D-1AEA is a modular AC axis drive produced by KEB within the F5 Combivert Axis Drives series. As an inverter and motor controller, it regulates torque and speed for asynchronous or synchronous machines used in conveyors, packaging lines, and positioning tables. The unit integrates with panel systems through its housing and communicates with upper-level PLCs through the standard control board. In an automation cell, it supplies vector control and manages braking energy through an onboard transistor stage.

The drive accepts a three-phase supply at 230 V AC/DC and routes that power through the size-12 inverter section. Under continuous loading, it delivers 16.5 A of output current, while internal IGBTs switch at 8 kHz to balance audible noise and heat generation. Motor capacities up to 5 HP are supported, and the enclosure has an IP20 rating for installation inside a protected control cabinet. The standard board includes an incremental encoder input and an initiator track, so closed-loop feedback can be processed without external option cards. The power stage requires three input phases, and the control architecture permits direct interfacing with the integrated braking element.

The braking stage uses the Integrated GTR7 transistor to channel excess DC-link energy to a resistor during rapid deceleration. Short disturbances are handled by a current reserve of 200% for three seconds, while the overcurrent trip engages at 240% to protect the power devices. Safe operation is specified up to an ambient temperature of 45 °C, permitting installation in most indoor production areas. During cold starts, the electronics remain stable down to the listed minimum temperature, and the encoder input maintains signal integrity during each control cycle. This arrangement supports controlled braking when the connected motor returns energy to the drive.
