Product Description:

The 09.F5.MDD-Y0P0 is an AC axis drive from KEB that belongs to the F5 Combivert Axis Drives series. This unit interfaces with 3-phase mains supplies and delivers regulated power to synchronous or induction motors used on conveyors, gantries, and positioning tables. By converting a fixed 400 V AC line into a variable voltage and frequency output, the drive lets machine controllers command speed, torque, and direction without mechanical gear changes or contactors.

The power section accepts a nominal line of 400 V and draws a rated input current of 6 A when operating at full load. Internally, the inverter stage can supply a continuous motor current of 4.1 A, corresponding to a rated apparent power of 2.8 kVA. Pulse-width modulation is generated at a factory setting of 8 kHz, while users may raise the carrier to 16 kHz for quieter motor acoustics at the expense of additional thermal stress. A short-time current capability of 7.4 A supports brief acceleration peaks, and overcurrent protection trips if phase demand becomes excessive. The drive contains no encoder feedback card, so applications that need speed or position loops must rely on open-loop V/Hz control or use an external feedback module.

Heat dissipation is managed through a finned heat sink with convection cooling, and the enclosure has an IP20 rating. The aluminum heat sink may reach 90 °C before derating occurs, with steady-state thermal losses of 80 W and DC-bus standby losses of 75 W. An electronic comparator trips at an instantaneous phase draw of 8.9 A, protecting the IGBTs from short circuits, while the nameplate output of 1.5 kW indicates the motor size the unit can drive continuously at sea level. The controller maintains rated operation up to 2000 m altitude, and the listed parameters are based on the standard switching frequency to balance audible noise and semiconductor heating.
