Product Description

The 13.F4.087-E409 frequency inverter provides efficient motor control for various industrial automation applications. It offers robust performance, precise speed control and customizable settings. This inverter supports a wide range of motor types.

The 13.F4.087-E409 frequency inverter is designed to deliver a nominal output current of 12 A for medium to high power motor applications. The system's line cross section is 2.5 mm², providing adequate current handling for most industrial environments. The inverter’s stall current at 16 kHz is 12 A that offers reliable torque delivery at high frequencies. The inverter also features a maximum heat sink temperature of 73 °C. The inverter incorporates a voltage boost function for the lower speed range to increase torque without compromising efficiency. However, in closed loop operation, this function is disabled. The inverter is sensitive to capacitive or inductive coupling in its input lines which can cause motor drift at standstill. Despite the presence of analog input filters, voltage fluctuations in the signal source can affect performance. Careful attention to signal quality and system grounding is recommended.

The KEB F4 Combivert frequency inverter series module operates with a maximum frequency of 16 kHz to provide precise speed regulation across a variety of applications. The inverter is equipped with 14 fixed parameter groups along with one free to define group that provides extensive flexibility for configuration. It features one differential voltage input for setpoint control (REF1 ±) and one programmable differential voltage input (REF2 ±). Additionally, two programmable analog outputs (A1, A2) enable integration with various control systems. These outputs along with the input signals can be finely tuned for offset and gain adjustments. The nominal input current of the model is 13.2 A ensuring efficient power usage for connected equipment.
