•= If an error occurred during the read or write request, this will be indicated to

the master by Resp1:Resp0 changing from 0:0 to 1:1. The parameter

number response (12 bits) will equal the parameter number that the master

was attempting to access, and an error code reflecting the failure cause will

be placed in the data / error code response word. For a list of possible error

codes, refer to section 10.4.

6. In order to perform another parameter read or write, the master must once again

send a “no action” code (Req1=0 and Req0=0), and the drive must once again

respond with an idle state acknowledge (Resp1=0 and Resp0=0) before the next

read or write action can take place. Until a “no action” code is sent to the drive,

the drive will ignore all data in the Parameter number / action word and

Parameter write data word. Also, as long as the master sends the “no action”

code, the drive will loop-back in the parameter number / action response word

and parameter data / error code response word whatever data is sent to it in the

corresponding output words.
