Note: Both 10F1 hex and 1F01 hex have the same function. You can set either object.
0x10F1 Hex: 2 Sync Error Counter Limit
This object defines the allowable number of failures when receiving process data. If the value of
the internal error counter in the SERVOPACK exceeds the value of this object, the SERVO-
PACK will detect an alarm (A12 hex) and change the ESM state to SAFEOP.
The SERVOPACK increments the internal error counter by 3 if the process output data is not
updated (i.e., if a reception event does not occur) when the synchronization event (Sync0)
occurs. When the process output data is updated normally, the internal error counter is decre-
mented by 1. The internal error counter is reset when the EtherCAT communications state
changes from SAFEOP to OP.
An example of internal error counter operation is shown below.
