Product Description:
The 18.F5.K1G-340F is an inverter drive produced by KEB as part of the F5 Combivert Axis Drives series. Intended for multi-axis machinery, the unit converts fixed three-phase mains power into variable voltage and frequency for controlled motor operation. This conversion allows connected motors to start, stop, accelerate, and decelerate in response to commands from a PLC. The drive mounts in the power cabinet between the mains contactor and the motor terminals, where it supplies regulated energy while processing feedback from the connected encoder.
On its I/O header, the drive provides an auxiliary frequency output in TTL format, simplifying direct connection to motion controllers that use 5 V logic. Position feedback is handled through a dedicated Hiperface interface, allowing absolute encoder data to be exchanged without an additional adapter card. The Unit B configuration supports a continuous output of 30 HP at 480 V, allowing a compatible motor to operate at its rated torque across the intended speed range. Electrical and thermal limits correspond to inverter size code 18, which establishes the applicable conductor cross sections and heat sink dimensions. The mechanical enclosure uses housing form factor G, which establishes the overall height and mounting-hole pattern needed for cabinet installation.
The drive includes a braking transistor that allows regenerative energy in the DC link to be dissipated during rapid deceleration. This integrated component eliminates the need for a separate external chopper module, although the connected braking arrangement must remain suitable for the application. The control electronics incorporate a safety board, allowing the drive to participate in safe torque-off circuits used by modern industrial machinery. Safe torque-off operation prevents torque-producing energy from reaching the motor when the associated safety circuit is activated. The control interface uses the Combivert F5 platform’s common diagnostic functions and keypad navigation, providing a consistent operating structure across compatible drive sizes.
