Product Description:
The 07.F5.B3A-Z000 is a variable-frequency axis drive produced by KEB for the F5 Combivert Axis Drives series. Installed between the mains supply and an AC motor, it creates a programmable output so manufacturing cells can coordinate spindle speed, feeder velocity, or indexing motion without mechanical gear changes. The drive acts as the regulated power stage in industrial automation loops, accepting commands from PLCs and delivering controlled current and voltage to the connected machine axis. This makes it suitable for motion tasks that need adjustable speed, controlled acceleration, and stable torque delivery across changing process conditions. Its role is to vary motor output electronically rather than through fixed mechanical transmission components.
The power section accepts an input of 230 V and can modulate the motor field up to 800 Hz. One differential analog input with a resolution of 11 bit captures speed or torque references, while a single analog output of the same precision feeds back process variables. A bank of 17 control terminals supports hard-wired signals, including 5 PNP-logic digital inputs, two form-C relay outputs, and four software-defined I/O points. Eight parameter sets allow quick changes between stored motor or recipe configurations without reprogramming. The unit is supplied without an encoder feedback card, and its braking transistor plus EMI filter are already mounted in the housing, which simplifies installation.
Dynamic behavior is tied to a carrier switching frequency of 2 kHz, which helps minimize current ripple during high-speed operation. For short acceleration bursts, the inverter can supply up to 125% of its nominal current, and an overcurrent trip threshold at 150% activates protective shutdown before semiconductor limits are exceeded. Control intelligence completes its scan loop every 2 ms, so torque commands and protection masks are refreshed quickly during variable load conditions. This response rate supports precise indexing and repeatable speed control during rapid start-stop operation.
