4.3.2 Servo system controller setting
(1) Setting instructions
When using the direct drive servo, set it as described in this section. For other servo parameters and
positioning control parameters, set them in the same method as that of MR-J3-
B servo amplifier.
The following servo parameters will be valid by turning the power of servo amplifier off once and then turning
it on again after writing to the servo amplifier from the controller.

Set as necessary.
When using QD74MH
or QD75MH
, set it with
sequence program.
It is necessary to set the
initial values of these
parameters at the startup
of direct drive servo.
Refer to (2) and (3) in this
section.
When using LD77MH
,
set it with GX
Configurator-QP
(SW2D5C-QD75P-E) as
necessary.
Note 1. The parameters having * before the symbol will be valid in the following conditions.
* : Turn the power of servo amplifier off once after the setting and then turn it on again, or execute the controller reset.
** : Turn the power of servo amplifier off once after the setting, and then turn it on again.
2. For the LD77MH
/QD74MH /QD75MH , make sure to set the initial value.
3. Pay attention on 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 LD77MH
/QD74MH /QD75MH . However, it does not reflect to the flash ROM.
When turning off, resetting the power of LD77MH /QD74MH /QD75MH 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
LD77MH
/QD74MH /QD75MH . In such a case, change it again.
4. Set QD74MH
and QD75MH with sequence program. (Refer to (2) of this section.)
