Product Description:

The 12.F5.B1D-3A00 is an inverter drive manufactured by KEB as part of the F5 Combivert Axis Drives series. It modulates voltage and frequency to control three-phase induction or synchronous motors, giving production equipment adjustable speed and torque. By converting a fixed mains supply into a regulated output, the unit coordinates conveyor sections, indexing tables, and auxiliary axes from a single cabinet location while system status is monitored through onboard I/O.

The drive operates from a 3-phase 400 V AC/DC supply and is housed in an IP20 open-frame enclosure for mounting inside a protected electrical panel. For analog control, it offers one input with 11-bit resolution, suitable for proportional speed references generated by PLC modules. The unit has 5 opto-isolated digital inputs that accept start, stop, and preset signals, and the controller samples all I/O every 2 ms to maintain timely response. Power devices are pulsed at a carrier rate of 8 kHz, balancing acoustic noise and thermal loading. Cooling is provided by standard forced convection, and no encoder feedback card is installed, leaving that slot free for future expansion. An internal GTR7 braking transistor is supplied as a mounted accessory, and the unit follows inverter size code 12.

During overload events, the inverter can deliver 180% of its rated current for short intervals, allowing acceleration demands to be covered without tripping. Continuous shaft power is limited to 5 HP, matching small pumps or material-handling drives that require moderate output. The GTR7 transistor directs excess DC bus energy to a braking resistor, ensuring controlled deceleration. Relay logic is available through an output rated at 30 VDC / 1 A for drive-ready signaling to safety interlocks. The available analog channel, digital inputs, and open encoder bay support application-specific tuning through the Combivert F5 parameter set.
