Product Description:
The 20.F5.A1H-34-F is an AC axis drive manufactured by KEB for the F5 Combivert Axis Drives series. It converts fixed three-phase mains power into a variable-frequency output for closed-loop motor control on single or coordinated machine axes. The inverter regulates speed, torque, and position for conveyors, winding stations, positioning tables, and other automated equipment. Its control functions allow the connected motor to respond accurately to changing load conditions and programmed motion commands.
At the I/O level, the auxiliary signal channel delivers a TTL square wave so downstream counters and position modules receive clean 5 V logic edges. Internal control logic is mounted on the factory-supplied Standard Board, which provides the baseline parameter set for velocity, torque, and field-oriented regulation tasks. Rotor feedback is accepted through a Hiperface interface, allowing absolute position data to be available immediately after power-up without a homing routine. With a motor rating of 50 HP, the inverter is suitable for mid-power equipment such as moderate-capacity extruders and centrifuges. The housing form factor is identified by code H, which indicates the heat sink depth and mounting-hole arrangement used for cabinet installation. These features support accurate feedback processing while keeping the control and signal connections within the drive enclosure.
The installed accessories include a braking transistor, which permits direct connection of resistor banks that dissipate regenerated energy during rapid deceleration. This arrangement helps prevent excessive DC-bus voltage when a driven load returns energy to the inverter. The leading number 20 identifies the inverter size and corresponds to its thermal capacity and current-handling range. The drive supports vector control for applications that require responsive torque regulation and precise motor behavior at varying speeds. It also supports scalar V/Hz control for applications with simpler speed requirements, allowing the control method to be matched to the connected motor and operating profile.
