6 Technical description
6.1 Digital servo amplifiers in the series AX2500
Minimum complexity
l up to 8 axes in a single system
l only one power supply feed and one auxiliary voltage supply per system
l shield connection directly on the servo amplifier
l all axes in a system can be parameterized through a single interface
l strongly reduced wiring expenditure by modular structure
l simple mechanical structure on DIN rails
Standard version
l 2 supply voltage versions: AX250x up to 3x230VAC and
AX251x up to 3x400VAC
l one size for the master and axis modules each, see page 35
l analog input
l fieldbus interface is integrated (standard: CANopen)
l RS232 is integrated
l pulse-direction interface is integrated
Supply power
l directly off electrical supply input (master only, B6 rectifier bridge,
integral power input filter and inrush circuit):
1 x 115V AC (AX250x only, unearthed operation is permitted)
3 x 115V AC (AX250x only, unearthed operation is permitted)
1 x 230V AC (AX250x only, unearthed operation is permissible)
3 x 230V AC (all types, unearthed operation is permissible)
3 x 400V AC (AX251x only, TN-system or TT-system with
earthed neutral point)
l fusing (e.g. fusible cutout) provided by the user
l integrated interference suppression filter for the supply input (for category 2)
l integrated interference suppression filter for the 24V auxiliary supply (for category 2)
l all shielding connections directly on the amplifier
l output stage IGBT module with isolated current measurement
Clock frequency can be switched from 8 to 16 kHz with
ASCII command (with power reduction, please contact
our customer support)
l regen circuit internal regen resistor as standard,
external regen resistor if required
l DC Bus link voltage 160...320V DC for AX250x
320...560V DC for AX251x
160...560V DC for AX252x
