Product Description:

The 12.F5.GBD-YA00 axis drive is produced by KEB and belongs to the F5 Combivert Axis Drives series. It sits between the plant power bus and an AC motor to regulate speed, torque, and direction in coordinated machine axes such as conveyors and packaging stations. In industrial automation, it translates control commands into precise three-phase output while monitoring current limits, temperature, and I/O status for controlled motion. This arrangement allows the drive to support repeatable starts, stops, and speed changes in equipment that runs through frequent duty cycles.

The drive accepts a line supply or DC bus of 400 V AC/DC, allowing direct connection to common power grids or rectified links. It can energize motors up to 5 HP and sustain overloads at 180% of rated current for short bursts, giving extra torque during acceleration. An overcurrent trip activates at 216% to protect the power stage. A rated carrier frequency of 8 kHz governs IGBT switching, balancing acoustic noise and switching losses while maintaining smooth motor current. The inverter size code 12 matches the heat sink area and bus capacity to these operating limits, and the standard cooling arrangement removes thermal energy through baseplate conduction and forced air.

I/O and reference channels support integration with PLCs and other machine-level controls. Two analog outputs are modulated at 3.4 kHz PWM with 10-bit resolution and can drive loads down to 100 Ω for speed or torque feedback. Command inputs arrive through a 12-bit differential analog channel and through 8 digital inputs that latch edge-triggered commands such as enable, direction, or quick stop, while status is returned by two digital outputs and two relay outputs. A regulated 10 VDC reference source supplies up to 4 mA for external potentiometers, keeping signal scaling stable. The absence of an encoder feedback card suits the unit for open-loop or sensorless vector control where feedback is estimated from motor parameters.
