From the output of the console i see you are sending the address 0x0460 and not the address 0x602c.

Hi cnc_freak,

Please tell me how to send the 0x602c, this address.

Waiting for your kind reply.

Hi tom, thanks for your reply. What kind of converter do you have? I have below converter, and manual. https://www.hexin-technology.com/shared/manual/HXSP-485_RS-232_RS-485_UserManual.pdf https://www.hexin-technology.com/RS-232_To_RS-485_Converter-Product-257.html How is it wired? This connector has...

You have to be more specific. What have you tried exacly? Do you managed to establish serial communication with the drive via kanalog? What is the console responding when you are running the ModubusMasterv1.c ? Hi there, thanks for your reply. it looks like i was not able to establish serial commun...

It is well writen in the commends of the c programm ModbusMasterv1.c.

Hi there,

thanks for your reply.

I have tried it and its not working, any suggestions???

Waiting for your kind reply.

Hi Amit, See the \C Programs\RS232\ModBusModbusMasterVer1.c example. Modify the ModbusMaster_MonitorList table to continuously read those registers into MBRegisters. Then modify ModbusMaster_RegUnload() to convert the MBRegisters into the KFLOP Axis Positions when appropriate. Hi tom, Thanks for yo...

Modbus typically works with 16-bit registers that can be read or written. Read the manual for your drives and determine which registers contain the data you need. Then connect your Drive to a PC (not Kanalog) and use the PC example in the link to verify you can read them. Hi tom, thanks for your re...

If you need to communicate with more than one drive you will need a rs232 to rs485 converter. Go to page 159 on the leadshine manual there is a description of the modbus protocol.In page 133 you wil see the address of the motor position register which is the 0x602C and 0x602D, which is propably the...

For ModBus see here . Hi tom, Thanks for your reply. I have studied that link that you shared, but i can't find that, How do i read the current absolute position from the drive, so i can avoid homing ?? I have connected kanalog rs232 to drive rs232 via cable., Is there anything that i am missing ? ...

Hi Amit, You would have to research the interface specification. I'm guessing Modbus? If so it would be too slow to use instead of the incremental encoder but could be possibly used on power up to avoid homing. Hi tom, Thanks for the reply. Modbus is the interface that is required by leadshine serv...

Hi tom, I am using KFLOP+Kanalog+Konnect, and currently i am using servo motor with 5000ppr incremental encoder. I want to use servo with in built 23bit Absolute encoder, with kflop, what connections has to made, here is the servo motor and drive that i am using. http://leadshine.com/productdetail.a...
