6.1  Axis status LEDs
Depending on the design of the axis controller (single-axis controller, double-axis control-
ler) up to 2 times 3 LEDs are provided as status indicators. The LEDs are on the front of 
the device and are assigned to axis 1 to axis 2 from top to bottom. The signicance of 
the LEDs is the same for each axis and is as follows:

•  Axis 1/2 = Indication of which axis is accessed via 
the controller's MMi
•  ERR = Error indication using ashing code
•  RUN = Ready / power stage active
