Product Description:

The 12.F5.A1D-YRA1 is a motor inverter manufactured by KEB and assigned to the F5 Combivert Axis Drives series. Within an automation cell, it regulates the speed, torque, and direction of a three-phase machine up to its stated power limit while exchanging control signals with PLCs and safety circuits. The drive integrates the power stage, logic, and pre-charge components required for closed-loop control, allowing it to serve as a single-axis actuator interface in material handling lines, packaging machines, and general motion systems.

A Standard Board inside the control section provides the baseline I/O, while an onboard braking transistor dissipates regenerated energy during rapid deceleration. The inverter uses size code 12 for a package geometry and current rating suited to machines that demand mid-range power. Electrical resilience is demonstrated by a control-burst withstand of 2 kV and a power-burst rating of 4 kV, preventing logic upset during mains disturbances. Radiated electromagnetic fields up to 10 V/m and electrostatic discharges reaching 8 kV are tolerated without functional loss, supporting reliable operation next to welding units and high-frequency drives. The housing has an IP20 protection rating, so installation inside a switch cabinet is expected to meet ingress requirements while permitting natural airflow across the heat sink.

The drive handles motors up to 5 HP, and it maintains continuous operation in ambient air from -10 °C to 45 °C with a heat sink temperature ceiling of 90 °C. Storage limits extend from -25 °C to 70 °C for spares kept on site. Reliable operation is specified up to 2000 m altitude with humidity not exceeding 85%, above which derating may be necessary. During freight, the electronics withstand shocks up to 100 m/s² for 11 ms, preserving component solder joints and connector integrity.
