Product Description:

The 14.F5.M1D-384A is an AC axis drive manufactured by KEB as part of the Combivert F5 Axis Drives series. Designed for induction motors, the unit uses closed-loop, field-oriented control to provide precise speed and torque regulation in industrial automation cells. It accepts three-phase mains power and adjusts the output frequency and voltage according to the motor’s operating requirements. This electronic control allows the connected machine to respond to changing loads without using mechanical throttling. Feedback from a compatible motor encoder helps the inverter maintain stable performance during acceleration, deceleration, and steady-speed operation.

The drive operates on networks with voltages up to 400 V AC. It supplies a continuous line current of 16.5 A and supports a rated motor output of 7.5 kW. During acceleration or rapid load changes, the permissible output current can rise to a peak of 29.7 A. The drive trips at 216% of rated current to protect its power semiconductors against excessive electrical loading. Its IGBT bridge supports a selectable carrier frequency of up to 16 kHz, allowing the switching rate to be adjusted according to motor noise and thermal requirements. A short-duration overload capacity supports temporary current surges that occur when machinery starts or encounters a sudden increase in load.

The D-size housing measures 90 × 250 × 181 mm, providing a compact format for installation in a standard control cabinet. It has an IP20 ingress protection rating and is intended for use inside a suitable ventilated enclosure. EMC performance is classified as C1, helping properly installed systems meet applicable emission limits. The nominal base switching frequency is 2 kHz, while the short-time current capacity reaches 180% of rated current for brief overload conditions. An integral braking transistor handles regenerated energy without requiring a separate external chopper. Motor feedback can be connected through TTL or SSI encoder interfaces, supporting closed-loop operation with compatible induction motors. Incoming power conductors connect to terminals associated with inverter size code 14, which provides an organized connection point for the three-phase supply.
