Hi@ Krupashankar
I am Trying to Read IU current Value when I send Command
Note: Motor is Stop mode not running
0x01,0x05,0x01,0x7A,0x00,0x00,0xFE,0x80
data received
0x1,0x85,0x1,0x7A ,0xF9,0xFF,0x5,0x1
Motor Ampere iU = FFF9,in decimal = 65529
again Send
0x01,0x05,0x01,0x7A,0x00,0x00,0xFE,0x80
data received
0x1,0x85,0x1,0x7A,0x5,0x0,0xF9,0x0
Motor Ampere iU = 5,in decimal = 5
I don't understand Why I get FFF9 value?
when I run motor got Correct Rpm by reading Register 0x7D; // Motor speed Register 125=7D
but IU current give 40,60,70 Reading & also FFC9 or different value FF
PL guide what I am doing Wrong & From where FF values came.
Thanks

Hi @sohail,
Register Iu is a signed 16-bit value representing the current in the U phase so you are reading both positive and negative current.
For more details please refer to section 3.2.7.1 Iu in iMOTION SRM.
Please let us know if further details is needed.
Thanks,
Krupashankar
