Dear experts,

Iam facing a problem in sinamics G120, i have configured two G120 drive with S71500 cpu through profibus DP (G120 CU240E-2DP and S7-1516-3PN/DP) . I configured drive through profibus GSD with free telegram and communication also established without any error . I configured some word in TRANSMIT direction (status word) because i need only feedbacks from drive and i didnt configure any word in RECEIVE direction (through DP iam not giving any commands or setpoint) screenshot attached for reference

Drive is running fine,but all of sudden drive goes to fault with fault codeF01910 FIELDBUS INTERFACE SETPOINT TIMEOUTwhen i check the drive while fault i didnt find any BUS fault indication only READY led is blinking in red, and I also checked in hardware configuration (PLC side ) while fault i didt find any communication loss in drive , its shows healthy. i dono why this fault is coming

when i remove profibus cable from drive it shows same fault but this time with BUS fault indication on both drive and PLC side so i hope cable is fine because iam getting feedbacks.

Problem is i cant figure out whether it is a profibus fault or some other because iam not getting bus fault while F01910

Please guide me to resolve this issue, i have changed some time parameters like P2044 and P2047 but still this fault is coming

Please help me to solve this issue
