Dear Team,
I want to communicate s7-300 & yaskawa a1000 vfd via PROFIBUS using PPO type 01 .
As per the manual i have sent the correct value to the first control word in PPO channel.
{ Move value 15 into PQW 264}
But my drive still shows Alarm BB at the startup.
Please advice me what could be gone wrong.
