9.1.10 Operating time counter
An operating time counter is implemented, which is designed for at least 200,000 operat-
ing hours. The operating time counter is displayed using the FCT parameterising software.
9.2 Operating mode and error messages
9.2.1 Operating mode and error display
A seven segment display is supported. The display and the meaning of the symbols shown
are illustrated in the following table:
Controlled RPM mode
The outer segments "rotate" on the display in this operating mode. The display
depends on the current actual position or speed.
The central bar is also active when the controller release is active.
The CMMP-AS servo positioning controller still needs to be parameterised.
(seven-segment display = "A")
Controlled torque mode.
(seven-segment display = "I")
Positioning ("xxx" represents the position number)
The digits are sequentially displayed
Reference travel "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
Error message with index "xx" and sub-index "y"
Warning message with main index "xx" and sub-index "y". Warnings are shown
at least twice on the seven segment display
"Safe standstill" is active for devices in the CMMP-AS family.
(seven-segment display ="H", flashing at 2 Hz)

9.2.2 Error messages
When a fault occurs, the CMMP-AS servo positioning controller displays an error message
cyclically in the seven segment display. The error message consists of an E (for Error), a
main index and sub-index, e.g.: E 0 1 0.
Warnings have the same number as an error message. The difference is that a warning is
displayed with a prefixed and suffixed hyphen, e.g. - 1 7 0 -.
