Product Description:

The 19.F5.A1H-35MA is an AC axis drive produced by KEB for the F5 Combivert Axis Drives series. It converts fixed-frequency, three-phase mains power into variable-voltage and variable-frequency output, allowing a motion controller to regulate motor speed and torque through vector or V/Hz control. The drive is intended for medium-power applications on extrusion lines, conveyors, and dynamometer stands that require controlled acceleration and consistent speed under changing loads. Its regulation capabilities help connected machinery maintain stable operating cycles without relying on direct line control of the motor.

A Standard Board provides the control layer, including baseline analog, relay, and fieldbus channels for connection to common PLC systems. The rated output is 40 HP, which supports motors with continuous power requirements of up to approximately 30 kW. This mechanical power rating is also available in the 230 V configuration identified as Unit B. The drive uses the footprint assigned to inverter size 19, which establishes the heat sink arrangement, mounting bolt locations, and required airflow paths. Its electronics are installed in an H housing that helps keep airborne oil mist away from internal components while directing cooling air across the fins. During rapid deceleration, an integrated braking transistor routes regenerated energy to an external resistor bank, helping prevent excessive voltage on the DC bus when high-inertia loads stop.

The drive shares parameter structures, diagnostic functions, and service tools with the broader Combivert F5 portfolio. This compatibility supports consistent configuration practices when several F5 drives operate within the same plant or machine system. The unit can deliver full torque from a three-phase 230 V supply, allowing it to operate compatible delta-connected motors from a lower-voltage power system. The size 19 frame provides space for adjacent bus bars and line reactors within the same panel bay. Side-flange service channels also provide direct access to control wiring for installation, inspection, and routine maintenance. These channels reduce the need to disturb nearby power connections when control terminals require access.
