Servo Parameter Read/Change Function
The servo parameters can be changed or displayed individually from Motion CPU. Use the following special registers to
change or display the servo parameter.
"Servo parameter write/read request" device
*1 Do not execute the automatic refresh.
Servo parameter write/read request procedure
■Procedure to write
1. Set the axis No., servo parameter No. and servo parameter setting value in SD805 to SD807.
2. Set "1: Write request" in SD804.
3. Check that "0" is set in SD804. (Completion of write)
■Procedure to read
1. Set the axis No. and servo parameter No. in SD805 and SD806.
2. Set "2: Read request" in SD804.
3. Check that "0" is set in SD804. (Completion of read)
4. Stores the read value in SD552.

write/read request
flag
• The "write/read request" is executed after setting of the axis No. and servo
parameter No.
1: Write request
2: Read request
• "0" is automatically set by Motion CPU after completion of servo parameter write/
read request. ("-1" is stored by Motion CPU at write/read error.)
User/System
SD805 Axis No. The axis No. to write/read servo parameter is stored.
R64MTCPU: 1 to 64
R32MTCPU: 1 to 32
R16MTCPU: 1 to 16
Sensing module (station mode): 601 to 608
User
SD806 Servo parameter
No.
The servo parameter No. to be written/read is stored in hexadecimal.
• Using sensing module (station mode)
SD807 Servo parameter
setting value
The setting value of servo parameter to be written is stored when "1: Write request"
is set in SD804.
