AX8108-0000-0000 | Single-axis module

The shaft module contains the DC link and inverter to supply the motor. Depending on the number of axes required, axis modules are attached to the power supply module to form a multi-axis servo system. Shaft modules with different ratings can be combined to allow optimized design of individual shafts.

Supporting a wide power voltage range from 100 to 480 V AC, the axis modules can be operated without restriction to any single power supply module. This flexibility simplifies machine configuration for any type of mains power source. The electrical connection is established without tools via the built-in AX Bridge: it automatically connects the DC link, 24 V DC control voltage and communicates via EtherCAT between linked modules . The DC link connection allows energy exchange during acceleration and braking, where the regenerative braking energy is mainly stored in the common DC link. If the energy exceeds the DC link capacitance, the brake resistor of the AX881x capacitor module is used to suppress the DC link voltage. The AX8000 multi-axis servo drive system includes new functions of safe drive technology with TwinSAFE: the AX8108, AX8118 and AX8206 axis modules include programmable TwinSAFE Logic corresponding to the EL6910 and allow for directly deploy safety application in servo drive. Users have a greater degree of freedom in implementing safety applications in drive technology systems, and programming flexibility facilitates the tailor-made design of appropriate safety drive technology with specific systems. The STO and SS1 safety functions can be implemented using the TwinSAFE axis module with ordering option -0100 (STO/SS1). These functions can be initiated via hard-wiring and via FSoE. For TwinSAFE axis modules with ordering option -0200 (Safe Motion), various internal and external drive signals are available to implement application-specific safety functionality. As usual, they can be connected to typical EL6910 pre-certified function blocks to form complex, safe drive functions such as SLS, SLP, etc. Depending on the application, the direction information Secure arrivals can be preprocessed directly in the drive so that the central TwinSAFE Logic only needs to process the information aggregated there.

The multi-response interface (ordering option -0x10) supports EnDat 2.2/22 and BiSS C digital encoding systems. Two more 15-pin D-sub connectors can be found behind the front cover. Therefore, one or two EnDat or BiSS encoders can be connected to the single-axis module. With dual axis modules, encoder interfaces are assigned to each axis.

These encoding systems can be used as primary or secondary response interfaces. Primary feedback means that these encoders are used as commutative encoders. This is the case with third party motors or if Beckhoff linear motors are operated with this feedback. Example of secondary feedback: The AM8000 servo motor has a spindle control OCT equipped with an additional linear encoder for increased accuracy.

TwinCAT 3 Drive Manager 2 serves as the testing tool. Thanks to its structured design and multiple functions, shaft operation is simple and intuitive.

TwinCAT 3 TE9000 Safety Editor and TwinSAFE TE9200 Loader/User must be used to perform safety projects.
