7. AUXILIARY FUNCTION
The sequence for when servo parameters are changed is as follows.
Dual port
memory
Parameter data
(internal memory)
Servo
amplifier
2)3) 1)
Position board
Servo parameters that were
changed are set in the parameter
data area of the internal memory
(1) in Fig. 7.3).
The parameter number for the
parameter that was changed is
set in the servo parameter change
number (Note).
The "changes to servo
parameters exist"
signal (PSCHG) on
the dual port memory
is turned on.
Turn off the
"changes to
servo
parameters
exist" signal
(PSCHG).

After confirming the
servo parameter change

parameter that was
changed using the
parameter read function.

Check if the
"changes to
servo parameter
exist" signal
(PSCHG) on the
dual port
memory has
turned on.
User program
processing
Turn on the
servo

read
complete
signal (PSF)
on the dual
port
memory.
Turn off the
servo
parameter
read
complete
signal
(PSF).
Wait until the
servo parameter
read complete
signal (PSF) on
the dual port
memory is
turned on.
Wait until the
"changes to
servo
parameter
exist" signal
(PSCHG) on
the dual port
memory
turns off.

Note. Check the servo parameter change number (monitor No.0590 to 05B7) corresponding to the servo parameter change
number 11
to 13 (PSN11 to PSN13).
