Product Description:
The 13.F5.A1D-39-A belongs to the F5 Combivert Axis Drives series manufactured by KEB. It is a field-oriented inverter intended to regulate the speed and torque of asynchronous motors used in conveyors, mixers, and general motion cells within automated plants. By converting fixed mains power into a variable AC waveform, the drive allows motor performance to match process demand without mechanical gear changes or throttling devices.
The power stage is supplied by a three-phase 400 V line and can deliver up to 7.5 HP of mechanical output when paired with a compatible motor. The output current can reach 21.6 A during transient peaks, while the continuous output current is 12 A under steady-state conditions. The IGBT bridge can switch at up to 16 kHz; this elevated carrier frequency helps reduce audible noise but increases switching losses, so a lower setting can be used when high current is required. The control logic refreshes all field-level signals every 1 ms, aligning the inverter’s response with fast PLC scan rates for coordinated multi-axis tasks. A built-in braking transistor protects the DC bus by diverting regenerated energy to an external resistor during overhauling loads or rapid deceleration.
The standard control board provides eight digital inputs that accept PNP/NPN signaling, two analog input channels, two analog output channels, and a pair of open-collector digital outputs rated for a combined 50 mA. An isolated relay block provides two changeover contacts that can switch auxiliary loads up to 30 VDC at 1 A. When applications require lower acoustic emissions, the carrier frequency can be set to the rated 4 kHz value, which balances electromagnetic stress and operating efficiency. The size 13 housing accommodates the control connections, relay outputs, and braking circuitry in a compact enclosure suitable for cabinet installation. The available input and output channels support direct connections to common sensors, switches, reference signals, and auxiliary control devices. This arrangement reduces the need for separate interface modules when the inverter is integrated into an automated machine.
