6 Diagnostics
6.1 Types of malfunction
Malfunctions can have different levels of severity:
Error
An error always results in an error response. The possible error responses are listed in section 6.4.1.
Errors must be acknowledged, i.e. reset. In terms of the CMMO-ST, errors can only be reset when their
cause has been eliminated.
Warning
Warnings have no influence on the behaviour of the drive and do not need to be acknowledged. The
cause of the warning should be eliminated in order that it does not lead to a malfunction.
Information
If an error message has been parameterised as “information”, it will not appear in the 7-segment
display. It is written into the diagnostic memory, however, depending on parametrisation.
6.2 7-segment display
The 7-segment display on the CMMO-ST provides information about operating modes, errors and
warnings. 4 characters are fundamentally displayed in succession, followed by a space.

7-segment display
The numbers of error messages are displayed in hexadecimal format. Table of error messages
section 6.4.2.
Wave function
The point flashes if the radio button “Identify this CMMO: on” has been clicked on the CMMO website
( section 5.3). This enables you to identify a certain CMMO-ST amongst a group of several units
(the connected CMMO-ST “waves”).
This wave function can also be activated from the FCT: Select the menu option “Component / FCT Inter-
face” and then click the “Search” button in the “FCT Interface” dialogue window to start the “Festo
Device Tool”. Then use the context menu of the CMMO-ST that has been located by the network scan to
select the option “Identification On/Off ”.
