[1] [7] [0] [1] to [F] [F] Lower limit value of each parameter setting range
Reads the permissible lower limit values of the parameters in the parameter
group specified with the command [8] [5] + data No. [0] [0]. Before reading the
lower limit values, therefore, always specify the parameter group with the
command [8] [5] + data No. [0] [0].
The decimal equivalent of the data No. (hexadecimal) value corresponds to the
parameter No.
12
[0] [8] [0] [1] to [F] [F] Each parameter symbol
Reads the symbols of the parameters in the parameter group specified with the
command [8] [5] + data No. [0] [0]. Before reading the symbols, therefore,
always specify the parameter group with the command [8] [5] + data No. [0] [0].
The decimal equivalent of the data No. (hexadecimal) value corresponds to the
parameter No.
[0] [9] [0] [1] to [F] [F] Writing enable/disable of parameters
Reads writing enable/disable of the parameters in the parameter group
specified with the command [8] [5] + data No. [0] [0]. Before reading writing
enable/disable, therefore, always specify the parameter group with the
command [8] [5] + data No. [0] [0].
0000: Writing enabled
0001: Writing disabled
