Product Description:
The 29.F5.A1P-90-D belongs to the F5 Combivert Axis Drives series from KEB. It is an AC drive intended for cabinet installation, where it converts three-phase mains power into regulated output for large-frame servo or induction motors used on extruders, presses, and coordinated multi-axis lines. By integrating power electronics with a standard control board, the drive provides closed-loop speed and torque regulation within the Combivert platform.
The drive is powered by a three-phase 400 V AC supply and provides a continuous output of 250 kW. Under nominal conditions, it delivers a phase current of 460 A, while transient overloads can reach 575 A without derating. An internal braking transistor dissipates regenerative energy, so external choppers are unnecessary for most deceleration profiles. The housing has an IP20 protection rating, which provides protection against accidental contact but requires installation in a clean electrical enclosure. A 10 VDC reference output is available for potentiometer speed setpoints, and the relay contact can switch 30 VDC at 1 A for run or fault signaling. The transistor outputs provide a combined current capacity of 50 mA DC for external status indicators or logic inputs. The base switching frequency can be set to 2 or 4 kHz to balance acoustic noise and semiconductor losses.
The control section accepts two analog inputs with 12-bit resolution. Retransmitted signals pass through an analog output filter operating at 178 Hz or a PWM stage operating at 3.4 kHz. The controller has eight digital inputs scanned every 1 ms for start, direction, and limit commands. Auxiliary encoder feedback enters through an incremental TTL D-sub connector, and a TTL auxiliary signal output supports follower drives. The mechanical envelope measures 340 × 960 × 454 mm, allowing the unit to mount beside other high-power converters. Its thermal design supports operation at a selectable carrier frequency of 2 or 4 kHz without additional cooling hardware.
