Product Description:
The 18.F5.M1G-344A axis drive is produced by KEB for the F5 Combivert Axis Drives series. This inverter applies closed-loop, field-oriented algorithms to control three-phase induction motors in material-handling, packaging, and general automation applications. Acting as a bridge between the plant supply and the motor windings, it modulates voltage and frequency according to real-time feedback so that speed and torque follow commands issued by a central controller.
It connects to either a three-phase mains supply or a DC bus rated at 400 V AC/DC. The unit draws current through an inverter size code 18 power stage. The switching network operates at a carrier frequency of 2 kHz, a setting that balances motor acoustics and drive efficiency. Under nominal conditions, the drive can supply up to 30 HP of mechanical power. Transient demands are accommodated by a short-term current reserve of 150%, while an overcurrent trip threshold of 180% protects the semiconductors and motor windings from sustained overloads. A built-in braking transistor dissipates regenerated energy during rapid deceleration, and convection cooling maintains thermal limits without external fans.
For mounting inside control cabinets, the housing follows form factor code G and carries a protection rating of IP20. The housing has a width of 170 mm, a height of 340 mm, and a depth of 255 mm, allowing tight side-by-side placement with other F5 modules. A TTL incremental encoder can be connected through the incremental and SSI ports, which support signal frequencies up to 300 kHz. An internal 150-ohm termination matches typical line drivers and helps preserve feedback signal integrity. The drive also accepts an optional second sensor and routes both feedback channels into its digital regulator, keeping position error minimal throughout closed-loop operation.
