Servo Parameter Read/Change Function - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

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
No. Name Meaning
SD552 Servo parameter Servo parameter
write/read request read value
*1
SD804 Servo parameter
write/read request
flag
SD805 Axis No.
SD806 Servo parameter
No.
SD807 Servo parameter
setting value
*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.
Details
The read value of servo parameter which executed "2: Read request" in SD804 is
stored.
• 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.)
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
The servo parameter No. to be written/read is stored in hexadecimal.
H
Parameter No.
Parameter group No.
• 0: PA • 5: PF
• 1: PB • 9: Po
• 2: PC • A: PS
• 3: PD • B: PL (MR-J4(W)- B only)
• 4: PE • C: PT (MR-J4(W)- B only)
Fixed to 0
• Using sensing module (station mode)
H
Parameter No.
Parameter group No.
• 0: Sensing SSCNET µ /H head module
(MR-MT2010)
• 1: Sensing extension module (MR-MT2100,
MR-MT2200, MR-MT2300, MR-MT2400)
The setting value of servo parameter to be written is stored when "1: Write request"
is set in SD804.
