8.2 Operating mode and error messages
8.2.1 Operating mode and error display
A 7-segment display is supported. The display and the meaning of the symbols shown are
illustrated in the following table:
Display Significance
The outer segments "rotate" on the display in the speed control operating mode.
The display depends on the current actual position or speed.
The central bar is also active when the controller release is active.
Controlled torque mode.
(7-segment display = "I")
P xxx Positioning ("xxx" represents the position record number)
The digits are sequentially displayed.
PH x Homing run. "x" represents the respective phase of the homing run:
0 : Search phase
1 : Slow moving phase
2 : Travel to zero position
The digits are sequentially displayed
E xxy Error message with index "xx" and sub-index "y"
-xxy- Warning message with index "xx" and sub-index "y". Warnings are shown at

8.2.2 Error messages
When an error occurs, the CMMD-AS motor controller shows a warning message cyclically
in the 7-segment display. The error message consists of an E (for error), a main index and
sub-index, e.g.: E 01 0.
The meaning and the measures for the error messages are compiled in the table below:
