12. COMMUNICATION FUNCTION (MITSUBISHI ELECTRIC GENERAL-PURPOSE AC SERVO PROTOCOL)
(4) Reading the setting
The following shows how to read the parameter setting. Specify a parameter group in advance. (Refer to
(1) in this section.)
(a) Transmission
Transmit the command [1] [5] and the data No. corresponding to the parameter No [0] [1] to [F] [F].
(Refer to section 12.4.1.)
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value
corresponds to the parameter No.
(b) Return
The slave station returns the data and processing information of the parameter No. requested.
For example, data "00120000270F" means 999.9 (decimal display format) and data
"000000003ABC" means 3ABC (hexadecimal display format).
When the display type is "0" (hexadecimal) and the decimal point position is other than 0, the display
type is a special hexadecimal display format and "F" of the data value is handled as a blank. Data
"0001FFFFF053" means 053 (special hexadecimal display format).
"008000000000" is transferred when the parameter that was read is the one inaccessible for
reference in the parameter writing inhibit setting of [Pr. PA19].
