Product Description:

The 21.F5.MBR-YU1F axis drive module is produced by KEB and belongs to the F5 Combivert Axis Drives series. Designed for cabinet installation, this inverter conditions a three-phase supply and delivers a controlled sinusoidal output so that connected motors can be started, accelerated, and stopped with precise electronic regulation in industrial automation cells. Its internal control platform exchanges speed and torque commands with higher-level PLCs, allowing coordinated motion between multiple mechanical axes in process lines, gantries, and material-handling equipment.

The auxiliary signal connector sources incremental feedback levels as a TTL square wave, giving the control board a clean 5 V logic stream for high-speed position counters. For absolute feedback, the integrated encoder port supports the Hiperface protocol, so a single hybrid cable carries power and bidirectional serial data between the drive and the feedback device. When connected to a 460 V input, the drive can energize motors up to 60 HP, which sets the output capability of its power stage. Mechanical dimensions follow the inverter size 21 designation, which sets the cooling surface area and terminal spacing used in the cabinet. The module is built in the R housing, a narrow form factor that fits densely populated cabinets while still allowing vertical airflow. A separate operating condition also lists 230 V motor use, showing that the power section supports both common voltage classes.

Within multi-axis architectures, this drive is classified as Unit B. That grouping places it in the higher-output section of the family and pairs it with matching DC-bus reactors in compatible systems. The TTL auxiliary channel can support synchronized homing by distributing a reference edge to downstream drives. The Hiperface link also works with a multi-turn sensor, allowing position information to remain available after a power interruption and helping motion sequences resume with less recovery time.
