Product Description:

The 15.F5.A1G-YR60 is an AC inverter drive produced by KEB for the F5 Combivert Axis Drives series. It serves as the power stage between a PLC and a three-phase induction or synchronous motor, converting fixed mains voltage into a variable voltage and frequency output for motion tasks in conveyors, packaging machinery, and coordinated axis groups. The drive is shipped with a Standard control board and no factory-installed encoder feedback card, allowing a feedback option to be added when closed-loop speed or position regulation is required.

The electrical section supplies up to 17 kVA of apparent power and a continuous motor phase current of 21 A. Line draw under nominal load reaches 27.3 A, so upstream protection devices must be sized accordingly. Output frequency is adjustable from zero up to 599 Hz, while the IGBT bridge can switch at carrier frequencies as high as 16 kHz to limit audible noise and improve torque resolution. Overcurrent detection trips at 43.2 A, halting pulses to protect the inverter legs. Housing form factor code G and inverter size code 15 indicate the mechanical frame that accepts field wiring tightened to 11 in-lb on the power terminals. A factory-mounted braking transistor pairs with an external resistor not smaller than 36 Ohm and can absorb up to 21 A of regenerative current during fast deceleration.

For short overloads, the inverter can deliver a peak of 36 A for 30 seconds, giving extra torque for acceleration or load transients without exceeding thermal limits. The enclosure has an IP20 rating, so the unit must be installed inside a clean control cabinet with forced airflow. The drive also carries a general motor rating of 15 HP, which matches the 230 V Unit B figure and aligns with its continuous current capability. The minimum safe resistor value is 36 Ohm, helping keep the braking element within its power dissipation range while the transistor modulates excess DC-bus energy.
