Product Description:
The 12.F5.C3D-3A0A is an axis drive manufactured by KEB for the F5 Combivert Axis Drives series. It operates as the speed and torque regulator between a plant controller and a three-phase induction or synchronous motor. This allows coordinated motion within automated machinery such as packaging stations, material-handling lines, and test rigs.
The drive accepts a three-phase input of 3-Ph 400 V AC/DC, and its output frequency can be modulated up to 800 Hz so high-speed motors remain within closed-loop command ranges. Short transient overloads are tolerated at up to 180% of the rated current before derating logic engages. Task execution inside the controller updates every 2 ms, a scan time suitable for position loops that demand minimal lag. The IGBT bridge chops the DC link at 8 kHz, and this switching rate limits audible noise while maintaining acceptable ripple in the motor current. Eight digital inputs selectable for PNP or NPN logic, two analog inputs, two analog outputs, and two transistor outputs form the primary field interface. A braking transistor and EMI filter are integrated, eliminating the need for separate dynamic-braking hardware and reducing conducted emissions.
The inverter delivers up to 5 HP of motor power through a frame classified as Housing D. All command and feedback conductors terminate on 29 control pins, providing a centralized interface for external wiring. Internal electronics draw from a stabilized bus of 24 V DC, so auxiliary sensors can share the same low-voltage source. Over-current protection trips when phase current reaches 216% of nominal, coordinating with the earlier short-time limit to help prevent thermal damage. With 12 as its inverter size code, the unit fits mechanical clearances used by mid-range F5 drives while still reserving panel space for relay contacts rated at 30 VDC and 1 A.
