Internal Product Review
The 04.F5.S3A-ZM00 is a KEB Combivert F5 axis drive designed for precise motion control on 460 VAC three-phase input. A rated motor power of 0.54 kW paired with an 8 kHz rated switching frequency gives the unit smooth and well-balanced low-power drive performance. The factory-installed braking transistor and EMI filter add strong integration value, making this drive a very capable choice for controlled axis applications.

Product Description:
The 04.F5.S3A-ZM00 is an AC axis drive manufactured by KEB and assigned to the F5 Combivert Axis Drives series. It converts fixed-frequency plant power into a variable output suited for vector or V/Hz control of asynchronous and synchronous motors, letting automated machinery run a rated mechanical load of 0.54 kW in continuous operation. By integrating both a braking transistor and an EMI filter, the unit minimizes conducted noise while allowing regenerative energy from decelerating axes to be dissipated safely.
The inverter accepts a three-phase supply of 460 VAC at 50/60 Hz and draws a rated input current of 1.8 A. Internally it delivers 1.0 A of sinusoidal output while the power stage is limited to 1.0 kVA. A carrier frequency of 8 kHz is the standard switching rate; at this setting the stall current is held to 1.6 A, preventing thermal overload during prolonged low-speed operation. Because no encoder feedback card is installed, the drive operates in open-loop mode unless an external feedback module is added. Pre-wired terminals accept 16 AWG conductors, simplifying cabinet assembly. The braking transistor and EMI filter are factory installed, so no extra panel space is needed for those functions. A minimum 5 A input fuse provides branch-circuit protection against line faults.
For applications that demand sharper dynamic response, the IGBT bridge can be clocked up to 16 kHz, although this raises switching losses. During rapid deceleration, the braking transistor channels up to 5.5 A through an external resistor that must not fall below 150 ohms; this keeps the intermediate DC bus within safe limits. Short bursts of 5.6 A are available for 30 s to clear inertial loads, and an overcurrent trip threshold of 6.7 A protects the drive against stalled shafts or wiring faults. These current limits help reduce stress on the power components during acceleration and deceleration.
