Reading setting values
The setting values of servo parameters can be read. Specify a servo parameter group in advance.
■
Transmission
Transmit the command [1] [5] and the data No. corresponding to the servo parameter No. [0] [1] to [F] [F]. The data No. is
represented in hexadecimal. The decimal converted from the data No. value corresponds to the servo parameter No.
■
Return
The slave station returns the data and processing information of the requested servo parameter No.
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).
"000000000000" is transmitted when the read servo parameter is the one that cannot be written/referenced according to [Pr.
PA19] (parameter writing prohibited).
Reading setting ranges
The setting ranges of servo parameters can be read. Specify a servo parameter group in advance.
■
Transmission
When reading an upper limit value, transmit the command [1] [6] and the data No. [0] [1] to [F] [F] corresponding to the servo
parameter No. When reading a lower limit value, transmit the command [1] [7] and the data No. [0] [1] to [F] [F] corresponding
to the servo parameter No.
The data No. is represented in hexadecimal. The decimal converted from the data No. value corresponds to the servo
parameter No.
■
Return
The slave station returns the data and processing information of the requested servo parameter No.
For example, data "FFFFFFEC" means "-20".
