4. OPERATION AND FUNCTIONS
(2) Sequence program example of servo parameters on the positioning module
POINT
For QD74MH /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. For this reason,
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.
Once the initial values are written to the flash ROM at startup, servo parameters
are not required to be written at next power on or later. If the module write with GX
Configurator-QP has been performed from QD75MH , however, initialize the
servo parameters again.
