(2) Servo system controller setting
(a) Setting precautions
The following servo parameters will be enabled by cycling the servo amplifier power after the controller
writes the parameters to the servo amplifier.

Set the items as
required.
Set QD75MH with
sequence program.
When you start up the
direct drive motor, initial
values of these
parameters should be
set. Refer to (b) and (c)
of this section.
Note 1. The parameter whose symbol is preceded by * is enabled with the following conditions:
*: After setting the parameter, power off and on the servo amplifier or reset the controller.
**: After setting the parameter, cycle the power of the servo amplifier.
2. For QD75MH , make sure to set the default value.
3. Note the followings.
If the parameter (servo parameter) of servo amplifier has been changed, it automatically reads the servo parameter and stores in
the buffer memory of QD75MH /LD77MH . However, it does not reflect to the flash ROM.
When turning off, resetting the power of QD75MH /LD77MH or turning off the control circuit power supply of servo amplifier
right after changing the servo parameter, the servo parameter may not reflect to the buffer memory of QD75MH /LD77MH . In
such a case, change it again.
4. Set QD75MH with sequence program. (Refer to (b) of this section.)
