(b) Sequence program example of servo parameters on the positioning module
POINT
For QD75MH , the parameter error (37. ) will occur if servo parameters are not
initialized.
The number of write time to the flash ROM is limited to 100,000. Therefore, try to
write to the flash ROM only when changing the servo parameter instead of writing
with every sequence program. When controlling multiple axes, write the servo
parameters to all axes.
1) Sequence program example when QD75MH is used.
The following shows the example of writing the axis No.1 servo parameter to the flash ROM.
After changing the servo parameter, turn on the power of QD75MH again or reset the CPU,
then send the setting value to the servo amplifier. Refer to (2) (c) of this section for the address of
the special setting parameters (No.PS ) of the servo parameters.

Note 1. Configure a sequence program where the servo parameters are written to the flash ROM only when a servo parameter is changed.
2. Change the sequence program of the servo parameter No.PS08 to the following sequence program for the magnetic pole detection
without the stroke limit (FLS and RLS).

However, do not change to this sequence program if using the stroke limit (FLS and RLS) at the QD75MH side.
