IDN 14 (S-0-0014) Interface Status
The communication phase (CPx) and communication fault flags. In the event of a communication fault the drive decelerates to a stop and is disabled, and the drive's communication phase returns to 0.
The communication interface fault summary bit ( IDN 11 , bit 12) is set.
The cause of the communication fault is latched within IDN 14 along with the communication phase in which the fault occurred.
The master may retrieve this information from the drive by reading IDN 14 before issuing a „Reset Class 1 Diagnostic“ procedure ( IDN 99 ).
If both bit 3 and bit 4 (MST and MDT failures) are set, this could indicate a signal loss (e.g., a broken optical fiber cable). In this case, the MST and MDT error counters ( IDN 28 and IDN 29 ) will not be incremented.
