Hi Mathan,
If it is the same iMOTION controller then we have to keep the node number same and
change the parameter set number to 0 and 1.
The node will be different for different iMOTION controllers.

Hi Mathan,
Request you to provide more details regarding your query
1) It would be great if you can provide more details regarding the design/application
2) Processor/iMotion device you would like to use and power board

Hi Viswa,
I am using Eval IMM101T-046M and controlling this eval board by stm32.
I have generated two different parameter files as User UART (the only change is UART node address and parameter set number) Multiple Motor parameter set support is Motor ID from UART.
I have merged this two-parameter file as mentioned in AN2020-25 and uploaded it by the MCE designer.
Then I tried the Load Parameter command to access the specific motor parameter file . But it is not worked.
How to Select a specific motor configuration?
SRM & AN2020-25 Both documents have load parameter command details but both have a different frame and CRC calculation.
So I need your support in controlling the motor.
Thanks
Mathan

Hi Mathan,
Thanks for your patience,
The SRM shall be the correct one. The multiple parameter AN will be revised soon.

Hi Viswa,
What is the procedure for controlling multiple motors?
How to active parameter set number?
Shall I use the same node address for more than one motor parameter file?
Thanks

Hi Mathan
PF the process to work with multiple motor parameters
- Set the multiple motor parameter, shown below is UART selection “Unique Identification number”
- Repeat for parameter set number 2 and 3 as desired for different configurations
- Use the VB script to generate combined file and program it using MCE designer.
PF the excel to generate combined file.
- Parameter load command for parameter set 01
0x01, 0x20, 0x20, 0x00, 0x00, 0x01, 0xDE, 0xDF

Hi Viswa,
the communication is not working, while it is handling multiple parameter files.
Here I have attached VBA & .ldf files(page 1 & 2 ). I have tried in both 57600 & 115200bps.
Can you re-confirm the load parameter buffer frame in the previous reply?
How to control the motor from MCE on handling multiple motors?

Hi Mathan
1) Is it possible to provide the screenshot as shown in the previous reply,
for both the parameter configurations generated?
2) What is the response received when the command is sent?
3) Can you power OFF the unit after programming the parameters and then check the communication.
4) Request you to follow the below thread to communicate with iMOTION controller using stm32
User Mode UART and Register Read (0x05) command not working

Hi Viswa,
Now I can able to handle multiple motor parameter files.
Upload files from pages 0 to 15 without any empty pages in-between. then only, can handle parameter files. Now I have uploaded the parameter files on pages 0 and 1. Previously I have used pages 1 & 2, and 2&3, that's why I didn't handle them.
Why are these issues occurring?
I can control the motor with both the parameter files. But there are differences in the Pole, inductance & resistance.
How is Motor working on both files?
Thanks
Mathan

Hi Viswa,
In the previous reply, I mentioned I could control the multiple parameter files. But now I could control only page 0. even though uploaded the parameter file through the MCE designer.
Today I tried, Both parameter file has the same configuration, only changes in the node address.
Page 0 Node 1 & Page 1 Node 2 and Page 0 Node 2 & Page 1 Node 1.I have used the same motor for both parameters files.
I could able to control only page 0, not page 1.
Thanks
