Wake Industrial LLC is not an authorized distributor of this product.
The KEB 07.F5.B1B-YZ0A is part of the F5 Combivert Axis Drives series and features 1 analog input and 1 analog output, both with 11-bit resolution. It supports five digital inputs with PNP logic, two relay outputs rated at 30 VDC and 1 amp, and has an input supply of 400V AC or AC/DC. This drive uses open loop flux vector control and includes a standard varnished cooling type and a GTR 7 braking transistor.
Internal Product Review
The 07.F5.B1B-YZ0A is a KEB F5 Combivert axis drive with BASIC open-loop flux vector control and a 400V AC or AC/DC input supply. A 2 ms I/O scan time and PNP input logic give the unit responsive machine handling and straightforward control integration. The built-in GTR 7 braking transistor is a valuable feature that makes the drive a strong choice for practical axis control.

Product Description:
The 07.F5.B1B-YZ0A is an axis drive produced by KEB for the F5 Combivert Axis Drives series. It functions as a power stage that conditions three-phase mains power and regulates motor torque and speed in automated machinery that does not require encoder feedback. Power electronics and control logic are integrated into a compact housing for use with conveyors, pumps, and other general-purpose loads. The drive can also interface directly with plant-level control networks to receive operating commands and report status information.
The power section accepts a line supply of 400 V AC, while the drive’s logic and gate circuitry are energized by an isolated 24 V DC rail generated internally. One differential analog input provides 11-bit resolution, allowing proportional speed or torque commands to be converted into digital setpoints. The single analog output uses the same bit depth, so operating values such as motor current can be returned to a PLC with consistent granularity. The drive provides five digital inputs that use PNP sourcing conventions, simplifying connections to standard sensor blocks. The lack of an encoder interface supports open-loop operation in applications that do not need closed-loop position feedback.
Input and output activity is coordinated through an I/O scan time of 2 ms, allowing command changes and status bits to be exchanged promptly for general-purpose motion tasks. Dynamic stopping energy is managed by the integrated GTR 7 braking transistor, which routes excess DC-link energy to an external braking resistor during rapid deceleration. Two form-C relay contacts can switch auxiliary loads rated up to 30 V DC at 1 A, providing dry-contact signaling for interlocks or motor contactors. Motion regulation uses the BASIC open-loop flux-vector algorithm to control torque and speed without encoder feedback. A varnished cooling assembly associated with housing code B supports convection airflow and protects the cooling surfaces during industrial operation.
