Product Description:
The KEB F5 Combivert Axis Drives, particularly the model 21.F5.A1R-76-A, boast unique features and specifications that are ideal for industrial use.
This model presents a rated power of 45 kW featuring high workload capacity due to the rated current of 180 A and a maximum current of 270 A. The capability to manage high-demand situations is also enhanced by a dual switching frequency control that can be programmable at 8 kHz and 16 kHz to suit the prevailing working conditions. The drive is fully compliant with the EMC standards EN 61800-3 and EN 61000-6, which means that it will not interfere with the electromagnetic emission in sensitive industrial environments. This 21.F5.A1R-76-A has an IP 20 protection class according to VBG 4 which is an indication of protection from solid objects but not water and this makes it suitable for indoor installations where there is no exposure to water splash. The drive’s operational reliability is also bolstered by its extensive thermal range with a storage temperature of -25 to 70 °C and an operating temperature of -10 to 45 °C. The safety measures are well enhanced with short-circuit and earth fault monitoring in compliance with the EN 60204-1 standards to promote the safety and durability of the system. The drive is designed with a modular housing style, and it has an optional book-style configuration that allows for compact design and versatile installation in different industrial systems.
It has dimensions of 450mm in width, 180mm in height, and 324mm in depth to offer a workable yet spacious platform for major configurations. It contains an output choke as an integral part of its design, to reduce voltage and current stress on the motor windings, and a harmonic filter can be installed to conform to international standards and minimize electrical interference. An integrated filter according to EN 55011/C1 is also provided, with housing options for B, D, or E, to minimize electromagnetic interferences and guarantee maximum performance in a wide range of industrial applications.
