How to read the torque value from V90 to S7-300?

Split from READING TORQUE VALUE FROM V-90 TO S7-1200 VIA PROFINET.

Hello,

There is no any block. User need to establish the communication, set appropriate telegram & can read/write parameters. Please read earlier posts of this thread. You need to read V90 drive r030, data type DW in PLC to know the actual torque smooth value.

Hi,

There is not standard block for data exchange between drive and plc. You just have to define drive in PLC hardware configuration then select telegram e.g. 2/2 (2 Words as inputs and 2 words as outputs). 

please note max count drive can send and receive is 16384 not 27648. If you need to see or adjust scale you may see reference speed, reference torque, reference voltage, reference current parameters. PIW 256 or PQW256 is represented in PLC program as input and output. 

sir i have s7 300 and set up the communication link between sinamics v90drive .can you tell me the step by step procedure to  read all trhe parameter from v90 to s7300 especially torque value and i am using 6/10 telegram
