Group 7 − Controller error
CPX error group 107 (CPX-MMI: [Controller error] )
No. Reset typeError levelMessage
74 No firmware FS Poff
Cause No firmware. No communication possible via fieldbus.
Measure  Firmware download with FCT.
75 User data damaged F2 N
Cause Inconsistent user data.
Measure  Perform data reset and re-commission the axis.
76 Unexpected restart: Possible data loss F2 N
Cause The CMAX was restarted unexpectedly; the user data could not be saved.
Measure  Check whether the user data is complete and correct.
 Check whether the CMAX is subjected to strong electromagnetic
interference, and eliminate this.
 Contact Support.
77 Firmware damaged FS Poff
Cause Checksum fault Firmware
Measure  Download Firmware.
 Contact Support.
Group 8 – Displacement encoder error
CPX error group 108 (CPX-MMI: [Encoder error] )
No. Message Error level Reset type
80 Displacement encoder not connected or communication faulty F2 N
Cause Displacement encoder/sensor interface was not detected when switching on.
Measure  Replace position measuring system/sensor interface; check the cables.
Cause Communication between CMAX and displacement encoder/sensor interface is
faulty.
Measure  Check cables of the axis string, valve and displacement encoder/sensor
interface systematically; replace if defective.
81 Hardware of the displacement encoder or sensor interface faulty F2 N
Cause Hardware of the displacement encoder or sensor interface defective.
Measure  Replace displacement encoder/sensor interface.
Cause Fault during initialization of the displacement encoder/sensor interface.
Measure  Replace displacement encoder/sensor interface.
 Check compatibility of the displacement encoder/sensor interface with the
firmware version of the CMAX.
