Internal memory
Parameter
This section describes the exchange of the servo parameters.
(1) Writing the servo parameters from QD74MH to servo amplifier
Some servo parameters become valid by turning OFF/ON of the power supply of
the servo amplifiers. (Refer to Section 6.8.)
Change procedure is shown below.
1) Change the servo parameters and write them to the buffer memory.
2) Execute the flash ROM write.
3) (Change the parameters after procedure 3), if not required.)
4) Turn the power supply ON of the servo amplifiers.
5) Turn the PLC READY ON. (The parameters changed can be transmitted to
the servo amplifiers.)
6) Turn the power supply OFF of the system and the servo amplifiers.
7) Turn the power supply ON of the system and the servo amplifiers.
(The parameters changed become valid.)
8) Turn the PLC READY ON.
