MVP 2021 kratmel Posted October 10, 2020 MVP 2021 Report Share Posted October 10, 2020 Hi, Some quastions: 1) Is it speed and 8E1 (simens default) settings commisioned corectly in V350 com settings? 2) Is it G120 setpoint channel sw. = Modbus, Control channel = Modbus? 3) Is it G120 correctly commisioned and all self autotune done and all autotune settings written to the drive . Drive do not allow to net control before autotune done (default). 4) What is with modbus status when command was send? maybe this document is useful: https://static1.squarespace.com/static/5357e4cfe4b02760ee8a9506/t/53ecf6f2e4b03c7a36fcfed3/1408038642976/MicroBridge+Modbus+Plus+to+G120+App+Note.pdf chapter Verifying the Installation Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted October 11, 2020 MVP 2021 Report Share Posted October 11, 2020 Do you have the wired Enable signal on the drive terminals connected (DI0)? Joe T. Quote Link to comment Share on other sites More sharing options...

Joe T. Hello Joe, DIO es connected to a sensor, The signal is ok I try with DI0 in ´1´ or ´0´ but the result is the same, the inverter is stopped. All the inputs have the right connection and I chek if the signals are OK. All is ok, but the problem persist.... 😞 Quote Link to comment Share on other sites More sharing options...

I respond your questions: 1) Is it speed and 8E1 (simens default) settings commisioned corectly in V350 com settings? The comunication it´s ok because I can write and read diffents parameters (I set 8 bits, Even and 1 stop bit) 2) Is it G120 setpoint channel sw. = Modbus, Control channel = Modbus? I can´t find the control channel parameter. 3) Is it G120 correctly commisioned and all self autotune done and all autotune settings written to the drive . Drive do not allow to net control before autotune done (default). Autotune is done 4) What is with modbus status when command was send? The modbus Status is 0 (communication OK Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted October 13, 2020 MVP 2021 Report Share Posted October 13, 2020 Hi, in Verifying the Installation chapter of document in my above post present Modbus registers that can be sw. OFF1 bit directly. Please try to do this for test - it is the same idea as Joe provide with DI0 but via software. Quote Link to comment Share on other sites More sharing options...

I try set the parameter 40003 ( number 2 in visilogic) but the communication state change to "5". Another question, the "big endian" formtat, used by Siemens, could be the origin of the problem? Thanks for your time and help! Best regards Mario Quote Link to comment Share on other sites More sharing options...
