Hi i am using EVAL M3 IM564 and EVAL M3 102T.

QUESTION 1
I want to run using UART.

So, first i send a message to MCE
(01 06 01 20 00 00 FE D9)

And i sent a message to operate at 3000rpm
like below.

01 03 00 00 b8 0b 47 f1

But operation is different that using ISD.

ISD is good condition.(3000rpm)
UART is working and then it stops.(2000rpm->stop)

why is it that?

QUESTION 2
Where are parameter lists?

I can't find it.

Thank you at all times.

Hi @kkkkjeong,

1) The USER UART protocol in section 2.3 User Mode UART of document iMOTION™ Motion Control Engine
Software Reference Manual is for Firmware version V1.03.03

This protocol snippet is valid only with MCE Designer and MCE wizard for older firmware version V1.03.03.

Can you please tell us what do you mean by ISD is it iMOTION Solution Designer?

2) Parameter list and register ID is present in document iMOTION™ Motion Control Engine Software Reference Manual:

•  Section 3.2 Motor Control Register.
•  Section 3.1 System Control Register
• Section 3.3 PFC Control Register
• Section  3.4 Script Register 

Index represents the register ID.

3) iMOTION supports multiple parameter to control different set of motors and hardware configurations, Parameter set number can be set from MCE Wizard Ques 31 Parameter Set Number.

For more details please refer to application note AN2020-25 Handling multiple motor parameters with iMOTION™2.0 

Thanks,

Krupashankar

1) Yes ISD is imoction solution designer.

Is this frame 3000 rpm control?
b8 0b(low, high) = >  3000

2,3) I got it. Thank you.

I solved that.

The relevant information was here.
0x3fff(16383) = 100%
