4.2.3. State bus
By means of the state bus X6, the supply module gives status
information like ready, overvoltage, and heat sink or resistor
overtemperature to the connected axis modules. The four state bus
cables must be taken from the supply module to the axis modules.
The terminals in the axis module which are next to each other are
internally bridged.
When the modules are ready to operate, the following levels are
applied at the terminal of the state bus:
•
Temp -> GND : approx. 0...2 V
•
RDY -> GND : approx. 0...2 V
•
V
max
GND : more than 2 V
These levels can only be measured when the state bus is
connected between the supply module and the axis modules.
