4 AUXILIARY AND APPLIED FUNCTIONS
(b) Procedure to servo parameter write/read
1) 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)
2) 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.
POINT
(1) New servo parameter is reflected to Motion CPU, therefore, the servo
parameter of Motion CPU side does not need to change.
(2) When the axis No., servo parameter No. or servo parameter setting value is
outside the setting range, "-1: write/read error" is stored in the servo
parameter write/read request flag. The setting value of servo parameter is
reflected to Motion CPU even when the write error occurred. Be sure to set
within the setting range.
