09.F5.C1B-LA0A by KEB

The 09.F5.C1B-LA0A is an axis drive produced by KEB and supplied within the F5 Combivert Axis Drives series. It converts fixed-frequency mains power into variable output for synchronous or induction motors. The compact unit provides velocity, torque, and position control in automated production lines.

This drive has 2 analog inputs and an equal number of analog outputs; each channel is processed at a 12-bit analog resolution to accommodate fine speed or torque references. Eight discrete commands reach the controller through 8 digital inputs, while two digital outputs report status or alarm flags to upstream devices. All field connections share a single 29-point terminal strip, and four software-assignable I/O points provide additional virtual flags for internal logic. Cycle updates occur with an I/O scan time of 2 ms, so commands and feedback stay synchronized with fast motion loops. The housing follows form factor code B and carries an IP20 enclosure rating, meaning live parts are protected against finger contact when the unit is installed inside a cabinet. Up to eight parameter sets can be stored, allowing different motor types or operating profiles to be recalled without reprogramming. The open-collector outputs can sink a combined current of 50 mA.

A GTR7 braking chopper with an integrated braking transistor is installed for dynamic energy dissipation during rapid deceleration. Control electronics draw from a 24 V DC internal supply, allowing the logic to remain active during mains power interruptions. Two relay outputs are available, each with a relay contact rating of 30 VDC / 1 A, for external interlocks or motor contactors. The drive supports PNP and NPN sensor wiring through its PNP/NPN terminal logic. The 29 control terminals provide separate connection points for shields, common conductors, and reference leads, allowing field wiring to follow electromagnetic compatibility practices.
