Product Description:

The 18.F5.A1H-36YF is an axis drive module manufactured by KEB for the F5 Combivert Axis Drives series. It operates as the power stage between a motion controller and an AC motor, supplying adjustable voltage and frequency so automated machinery can match motor speed to process demand. Integrated current sensing supports closed-loop regulation, while overspeed monitoring helps protect connected machinery during rapid changes in velocity. The module is suitable for servo and spindle duties in packaging equipment, material-handling systems, and coordinated multi-axis machines.

The auxiliary signal output uses TTL-level signaling, providing clean square-wave timing for incremental encoders or external counters. A diagnostic edge can be routed directly to a compatible PLC high-speed input without an additional line driver. Motor feedback is accepted through the Hiperface interface, which carries absolute position words and incremental track data over one cable. The drive supports motor output up to 30 HP, allowing it to operate medium-frame induction or synchronous motors. Housing format code H indicates the heat sink profile and mounting hole pattern used for this configuration. A built-in braking transistor directs regenerated energy to an external resistor, helping inertial loads decelerate according to programmed ramps.

The mechanical outline corresponds to inverter size code 18, establishing the cabinet space, busbar spacing, and airflow arrangement required for installation. The drive can operate with a DC link supplied from 480 V mains, providing compatibility with common industrial power systems. Its factory-installed Standard Board contains parameter memory, analog inputs, and fieldbus headers for connection to the surrounding control system. Adequate clearance around the heat sink and ventilation path is necessary to prevent heat accumulation during continuous operation.
