7.8.4 Identifying the encoder. Consistency check (error 4026).
At the end of the Sercos initialization process (system start-up, machine value reset or
validation), a consistency check is performed on the encoder data. If the data detected and
saved do not match all the FeeDat and EnDat feedbacks, the CNC will display error 4026
(encoder FeeDat/EnDat data mismatch), indicating the ID of the feedback in which the
mismatched data has been detected. Error 4026 will continue until the mismatch causing
it has been corrected.
Correcting error E4026.
When an error 4026 occurs, the person responsible for the position in operation must check
the configuration of the feedback producing the error, and ensure that the detected data and
the validated data match, using one of the following methods:
• Changing the encoder, replacing it with the previously validated one. Substituting the
encoder, even it is with another with equivalent functions, will continue to show error
E4026.
• Expressly adding the new encoder, validating the new data. This option must be
implemented in Setup mode so that the changes are made permanent.
Exceptions to error E4026.
The CNC only displays error E4026 when the FeeDat/EnDat feedback has valid data and
is active.
• If a FeeDat/EnDat feedback does not have an encoder connected, or the parameter
reading process is erroneous (incorrect CRC), the error will not appear, even if there are
validated data. The CNC displays the feedback errors reported by the module itself.
• If all the axes that use a FeeDat/EnDat feedback are parked, the CNC thinks that the
feedback is not being used. The CNC disables the counter alarms and therefore will not
report the error E4026.
The User mode can also be used to modify the parameter settings of the feedbacks and add the new
encoder data (either from the machine parameters or from the diagnosis mode), but this change will
be temporary. When the CNC is shut down, the data are lost.
