14.5.3 Parameter
(1) Specification of the parameter group
To read or write the parameter settings, etc., the group of the parameters to be operated must be
specified in advance. Write data to the servo amplifier as follows to specify the parameter group.
Command Data No.
Transmission
data
Parameter group
[8] [5] [0] [0] 0000 Basic setting parameters ([Pr. PA_ _ ])
0001 Gain/filter parameters ([Pr. PB_ _ ])
0002 Extension setting parameters ([Pr. PC_ _ ])
0003 I/O setting parameters ([Pr. PD_ _ ])
0004 Extension setting 2 parameters ([Pr. PE_ _ ])
0005 Extension setting 3 parameters ([Pr. PF_ _ ])
000B
(Note)
Linear servo motor/DD motor setting parameters
([Pr. PL_ _ ])
Note. This is not available with the MR-J4-03A6 servo amplifier.
(2) Parameter group reading
The following shows how to read the parameter group set with slave station.
(a) Transmission
Transmit command [0] [4] and data No. [0] [1].
Command Data No.
[0] [4] [0] [1]
(b) Return
The slave station returns the preset parameter group.
0 0
Parameter group
0: Basic setting parameters ([Pr. PA_ _ ])
1: Gain/filter parameters ([Pr. PB_ _ ])
2: Extension setting parameters ([Pr. PC_ _ ])
3: I/O setting parameters ([Pr. PD_ _ ])
4: Extension setting 2 parameters ([Pr. PE_ _ ])
5: Extension setting 3 parameters ([Pr. PF_ _ ])
B: Linear servo motor/DD motor setting parameters ([Pr. PL_ _ ])
0
(3) Reading symbols
The following shows how to read symbols of parameters. Specify a parameter group in advance. (Refer
to (1) of this section.)
(a) Transmission
Transmit the command [0] [8] and the data No. [0] [1] to [F] [F] corresponding to the parameter No.
(Refer to section 14.4.1.)
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 symbol of the parameter requested.
0 0 0
Symbol characters (9 digits)
