Product Description:

The 19.F5.MAH-YU1F is a drive inverter supplied by KEB in the F5 Combivert Axis Drives series. It converts three-phase mains power into a variable-frequency output so induction or synchronous motors can follow commanded speed and torque references. By combining current control, field-oriented algorithms, and fault monitoring in one unit, the inverter links a PLC to the mechanical load for conveying, winding, and positioning duties in automated production cells. Continuous regulation of motor current helps the axis respond smoothly during acceleration, deceleration, and load changes. The integrated control functions also reduce the need for separate external processing between the drive and the motor.

The auxiliary signal terminals emit TTL pulses, allowing encoder index marks or drive status bits to reach digital controllers without additional line drivers. Position feedback enters through a Hiperface interface, so the inverter can read absolute rotor angle during startup and keep commutation stable at low speed. This feedback path also supports accurate rotor alignment when the motor is holding position or changing direction. The power stage supports 40 HP, which suits medium-frame motors in this class. Its mechanical layout uses form factor H, which sets the heat-sink depth, mounting points, and airflow path, while inverter size 19 uses matching gate boards and bus capacitors across related power variants.

For installations powered from 230 V mains, the Unit B version is intended for lower-voltage operation. In system cabinets that include auxiliary PLC modules, the shared communications bus passes status information and alarms to the central HMI, so operating data remains visible without separate signal converters. This arrangement keeps control wiring more direct between the inverter and surrounding automation hardware. It also helps the drive exchange motion-related data with the rest of the cabinet while maintaining the same basic control behavior across the platform.
