13. USING A LINEAR SERVO MOTOR
(2) Servo system controller setting
(a) Setting instructions
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.

Note 1. The parameter whose symbol preceded by * can be validated with the following conditions.
* : Turn off the power and then on again, or reset the controller after setting the parameter.
**: Turn off the power and then on again after setting the parameter.
2. For the QD75 MH , make sure to set the factory setting.
3. GX Configurator-QP(SW2D5C-QD75P) of Ver.2.29F or later supports the MR-J3- B linear.
4. Note that the following.
When a servo amplifier parameter (servo parameter) is changed, the controller automatically reads the servo parameter and
stores the new servo parameter in the buffer memory of the QD74MH , QD75MH or LD77MH. However, the new servo
parameter is not reflected in the flash memory.
Right after the servo parameter is changed, if the QD74MH , QD75MH or LD77MH is turned off or reset, or if the control circuit
power supply of the servo amplifier is turned off, the new servo parameter may not be reflected in the buffer memory. In this case,
change the servo parameter again.
