Response Data Details
There are positive responses and negative responses.
The positive response indicates normal operation and the negative response indicates an error.
14.7.1
Positive Responses
There two kinds of positive responses, responses that return data (for commands such as
PRM) and responses that do not return data (for commands such as SVON).
For commands that require data to be returned, refer to the description of the individual com-
mand for details on the structure of the response’s character string.
For commands that do not require data to be returned, the positive response is “OK” unless
parameter PnB02 is set to 0. If PnB02 = 0000h, there is no response.
Structure of the Response “OK”
OK [SP] [SP] [SP] [SP] [SP] [SP] [SP] [SP] [SP] [CR] [LF]
Note: In ASCII, the [SP] character is 20h, the [CR] character is 0Dh, and the [LF] character is 0Ah.
14.7.2
Negative Responses
There will be no response if one of the following errors is detected: a parity error (E48E), fram-
ing error (E49E), or overrun error (E4AE). There will be no response to a global command or a
command with an incorrect axis number.
In all other cases, a negative response will be returned if an error is detected.
Structure of the Negative Response
Note: In ASCII, the [SP] character is 20h, the [CR] character is 0Dh, and the [LF] character is 0Ah.
