AX8810 - capacitor module

The capacitor module extends the DC link capacity and is particularly suitable in combination with the 1-
phase supply of the AX8620-1000 for supporting the DC link. Voltage peaks during motor braking are
absorbed and stored. This largely avoids the need for connecting the external brake resistor and reduced the
power dissipation.

Positioning within the system

Supply voltage: 100 V
For this supply voltage, an optional AX8810-0000 capacitor module should be placed directly to the right of
the AX8620 or AX8640 power supply module. It is recommendable to configured the AX8000 multi-axis
servo system starting from the largest rated output current (e.g. AX8118) down to the smallest rated output
current (e.g. AX8108).
In our example, a system group is structured as follows:
Power supply module AX8620 → capacitor module AX8810 → axis module AX8118 (18 A rated output
current) → axis module AX8206 (2 x 6 A rated output current) → AX8108 (8 A rated output current)
