Product Description:
KEB manufactures the 10.56.20B-1229 as part of its F5 Combivert Axis Drives series. The compact drive controller modulates the speed of asynchronous and synchronous machinery used in industrial automation. By converting fixed mains voltage into a variable output, it lets production equipment match motor speed to process demand, improving accuracy and limiting mechanical stress. This variable output also supports controlled acceleration and deceleration, reducing abrupt changes in motor speed during automated operating cycles.
The drive belongs to the 400 V voltage class, so it connects directly to standard three-phase factory supplies without an isolation transformer. It can energize motors up to 3 HP, which represents the maximum continuous shaft power the inverter can deliver under nominal ambient conditions. The unit is configured as a frequency inverter, producing a pulse-width-modulated output for closed-loop or open-loop speed regulation. Dynamic stopping energy is routed to an external resistor through terminals PA and PB, helping prevent DC-bus overvoltage during rapid deceleration. For applications that require position feedback, an incremental encoder can connect to the dedicated UVW interface, allowing commutation and speed monitoring across the operating range. The feedback connection provides the drive with rotor movement data needed for applications that require more precise motor regulation.
A programmable auxiliary output provides logic-level status at the TTL threshold, enabling a PLC to read fault or ready signals without additional interface hardware. The motor cables connect to terminals U, V, and W, using a conventional three-phase layout that simplifies field wiring and service access. The drive is compatible with a three-phase AC motor, supporting stable vector or V/Hz control across the load curve. Mechanical integration is guided by housing form factor code B, and the enclosure depth aligns with cabinets that use the same Combivert size matrix. Inverter size code 10 groups the unit with drives that share the same heat sink capacity and mounting-hole pattern. These common physical characteristics allow consistent cabinet spacing and mounting arrangements across compatible Combivert installations.
