ASCII Object Description
The Beckhoff AX2000 and AX2500 drive contains numerous ASCII objects to read or manipulate internal parameters. These ASII objects can be accessed fieldbus-independently via ASCII commands in read- and some of them even in write mode. Some networks are using the ASCII commands during initialization of the axes through TwinCAT (e.g. Beckhoff Lightbus or Real-Time Ethernet). However, not all parameters are relevant in combination with TwinCAT NC-PTP or TwinCAT NC-I.
In any case, the support of the individual command depends on the Firmware revision of the drive (=> VER)!
A listing of the supported commands can be found under: AX2xxx Reference - ASCII Object Description.
At drives used under SERCOS, similar parameters are defined according to the IEC 61491 standard. For a description of the Sercos IDent Numbers supported by AX2000 respectively AX2500, please refer to: AX2xxx-B750 Reference. If a dedicated IDN matches the function of one of the ASCII objects, it is named in the table of the correlating IDN (for example: S-0-0030 == VER).
