Product Description:
The 18.F5.A1R-76-A is a configured variable-speed drive module produced by KEB for the F5 Combivert Axis Drives series. Designed as the active inverter portion of a multi-axis system, the unit interfaces with synchronous or induction motors to regulate speed, torque, and position in automated machinery. Within an installation, it forms the link between the facility’s three-phase mains and the motor windings, delivering pulse-width-modulated voltage in response to fieldbus or analog commands. This regulated output allows conveyors, gantries, and processing equipment to follow programmed motion profiles while the drive manages motor current and operating speed.
The drive is fitted with a standard control board that provides basic control I/O, encoder handling, and serial diagnostics for setup and closed-loop operation. When connected to a 480 V supply, the converter supports a maximum shaft output of 30 HP, providing the power required by compatible mid-frame motors. The chassis uses housing code R, which corresponds to its heat sink length, terminal spacing, and cabinet depth requirements. The size designation 18 identifies the power stage and bus capacity used for this model. During dynamic deceleration, a factory-installed braking transistor directs regenerated energy to an external braking resistor instead of allowing excess energy to remain on the DC bus.
The drive uses the keypad, fieldbus, and PC-based configuration procedures associated with its product platform. Its control connections support integration with automation systems that provide motion commands, operating references, and status monitoring. Encoder handling allows the drive to receive motor feedback for closed-loop speed and position regulation, while the serial diagnostic interface provides access to operating data and drive parameters. Cabinet installation must provide suitable clearance around the housing so heat can move away from the power stage during sustained operation. The external braking resistor must be selected and connected according to the regenerative energy produced by the motor and load during deceleration.
