Product Description

AX2516-B900 is a Beckhoff AX2500 series digital servo amplifier master module. Its input voltage rating is 230 to 400 Volts. The amplifier works with three-phase input. The maximum installed load for operation can go up to 12 kVA in a multi axis system. Rated DC bus link voltage is 320 to 560 Volts. Rated output current of the AX2516-B900 amplifier is 6 Amps rms at 8 kHz. The peak output current at 8 kHz is 12 Amps rms. Range of output stage clock frequencies is 8 to 16 kHz. The default is 8 kHz and increasing the frequency leads to output power reduction. Valued for minimum and maximum load inductance are 7.5 and 40 millihenry. The rated and quiescent heat dissipation values are 60 Watts and 15 Watts.

The amplifier weighs 3 kilograms. It approximate dimensions are 267 x 100 x 240 millimeters. The normal mounting position is vertical. With an IP20 rated enclosure, the AX2516-B900 amplifier is designed for indoor use. Outdoor use requires mounting in a suitable cabinet. A cooling fan provides ventilation and effective heat dissipation. Beckhoff requires adequate forced ventilation in the cabinet where the amplifier is mounted. Ambient temperature and altitude for rated output are 0 to 45 degrees and 0 to 1000 meters AMSL. The relative humidity in the operating environment should not exceed 85% without condensation. Pollution level compliance of the unit is 2 as per EN 60204. The vibration class of the unit is 3111 according to IEC 721-3-3. During operation, the amplifier emits noise that does not exceed 45 dB(A). Beckhoff recommends wires with 1.5 mm2 for the AC power connection. The maximum permitted motor cable length is 25 meters.
