Explanation
General term for linked modules of the AX8000 series
Component to which the motors are connected.
Toolless connection of the DC link, the EtherCAT fieldbus system
and the system supply with the power supply module and the
connected modules through a rail system with quick coupling.
When the DC-DC link capacitors can no longer absorb energy
generated by braking of the motors, it is fed to a brake resistor and
converted to heat.
Braking of the motors generates regenerative energy, which is fed
back to the DC link.
Component to which up to 2 motors can be connected.
Component to which only 1 motor can be connected.
Component that is connected to the mains supply and supplies the
connected modules with direct voltage via the DC link.
Functional earth
Safety over EtherCAT protocol
Component that can make additional functions available.
Earth connection
Easily accessible diagnostic points for the main operating voltages.
Term for the Beckhoff Automation safety technology.
STO (Safe Torque Off) is a TwinSAFE safety function for drive
technology.
TwinSAFE is an open and scalable safety technology from
Beckhoff Automation.
DC accumulators (capacitors) for supplying the drive modules with
direct voltage.
Connection between the DC links of supply modules and
connected axis modules with AX bridge.
