Product Description:
The 12.F5.CBD-3A0A is an axis drive produced by KEB for the F5 Combivert Axis Drives series. This compact inverter converts three-phase mains power into controlled motor voltage and frequency, allowing a PLC to regulate speed and torque on a single machine axis. Within an automation cell, the unit can meet the dynamic requirements of synchronous or induction motors. Its slim housing supports installation in panels where available mounting space is limited. The drive uses a heat sink to transfer internally generated heat to the surrounding air.
The drive processes velocity and torque commands through an analog input with an 11-bit resolution, while its digital inputs have a 1 ms scan interval for capturing fast control events. A built-in braking transistor controls the transfer of regenerated energy to a suitable braking resistor. The input section accepts a three-phase 400 VAC supply or a compatible DC input and draws 13 A at rated load. On the output side, the converter delivers up to 6.6 kVA of apparent power. Its peak current can reach 216% of the rated value during momentary overload conditions, while shorter acceleration intervals may operate at 180% current. The drive supports motors rated up to 5 HP. Status changes are transmitted through a relay contact rated for 30 VDC and 1 A, allowing external control equipment to monitor operating conditions.
Nominal power dissipation is 160 W, and the aluminum heat sink releases this thermal energy through natural convection. The power stage operates at a rated switching frequency of 8 kHz, which balances motor current control with inverter heat generation. Upstream circuit protection can use a maximum main fuse rated at 20 A gG. The motor output supplies a continuous phase current of 9.5 A, while the internal short-time limit governs temporary torque-boost intervals. Natural airflow across the heat sink fins helps maintain acceptable semiconductor junction temperatures without a separate cooling fan. The compact control section coordinates the analog inputs, digital inputs, braking function, and relay output during axis operation.
