Product Description:
The 12.F5.A1D-YRA0 is an axis drive produced by KEB for the F5 Combivert Axis Drives series. It converts a fixed or rectified mains supply into a regulated three-phase output for controlling the speed and torque of servo and induction motors in automated machinery. The unit combines control logic, signal processing, and power electronics on a single chassis, allowing it to support closed-loop motion tasks without additional interface cards. Its integrated design also reduces the number of separate components required within a control cabinet.
The standard control board provides eight digital inputs with a scan time of 1 ms. Two analog inputs have a resolution of 12-bit, while two analog outputs have a resolution of 10-bit. The analog channels support voltage or current signals, and the outputs use a pulse-modulation frequency of 3.4 kHz to provide smooth reference signals for connected devices. A separate encoder port accepts pulse streams up to 300 kHz and has an internal termination resistance of 150 Ω. No encoder feedback card is installed, so the port is intended for compatible incremental sensors. The I/O arrangement corresponds to inverter size code 12. Two additional relay contacts can switch low-power loads up to 30 VDC at 1 A, while a transistor output can supply 50 mA DC to status lamps or interlock circuits.
The power section accepts a three-phase input of 400 V AC or power from an equivalent DC bus. It can energize motors rated at 5 HP without derating under the stated operating conditions. Command, feedback, and field wiring connect through 29 numbered screw terminals, which provide centralized connections for cabinet wiring. The drive includes a factory-mounted braking transistor that controls excess regenerative energy by directing it to a suitable braking resistor. Standard cooling uses the drive’s internal airflow path to remove heat during continuous operation. The relay output remains suitable for low-power switching, while the open-collector output protects the onboard transistor by limiting the connected current load.
