Note:
The system acknowledges an interchange of the encoder systems ERN 1387 (previous
incremental system) and EQN 1325 (absolute encoder system) during parameterization or
connection by aborting the measured value acquisition. The following incorrect combinations
are possible:
ERN 1387 present, EQN 1325 parameterized:
Abortion via recognition of missing EnDat interface on ERN 1387 (MD 1023, bit 11 or bit 12
set)
Only for FDD:
EQN 1325 present, ERN 1387 parameterized:
Abortion via recognition of missing C/D tracks for EQN 1325 (MD 1023, bit 9 set)
