Chapter 1 Servo Parameter Details; Explanation Of Servo Parameters - Mitsubishi Electric MELSERVO-J5 Series User Manual

SERVO PARAMETER DETAILS
Restrictions
Settable servo parameters and values depend on the controller model, servo amplifier firmware version, and MR
Configurator2 software version. For details, refer to the controller user's manual. Refer to the Mitsubishi Electric FA site for the
latest software version of MR Configurator2. In addition, the firmware version of the servo amplifier can be checked with MR
Configurator2 or by other means.
When using servo motors with functional safety, executing software reset may trigger [AL. 016 Encoder initial communication
error 1]. If [AL. 016] occurs, cycle the power.
Precautions
Never make a drastic adjustment or change to the servo parameter values as doing so will make the operation unstable.
Do not change the servo parameter settings as described below. Doing so may cause an unexpected condition, such as
failing to start up the servo amplifier.
• Changing the values of the servo parameters for manufacturer setting
• Setting a value outside the range
• Changing the fixed value in each servo parameter
When writing servo parameters with the controller, make sure that the control axis No. of the servo amplifier is set correctly.
Failure to do so may cause the servo parameter settings of another axis to be written and result in the servo amplifier being in
an unexpected condition.
Some servo parameters are adjusted automatically. For example, auto tuning automatically adjusts gain servo parameters.

Explanation of servo parameters

For how to interpret the servo parameter numbers, refer to "Interpreting servo parameter numbers" in User's Manual
(Introduction).
The following explains how to read the details of servo parameters.
Item Explanation
No. Indicates the servo parameter No., which
can be identified by the servo parameter
group and number.
Symbol Indicates the abbreviation of the servo
parameter.
"*" added to abbreviations means the
following.
* or **: After setting, cycle the power or
reset the software.
Name Indicates the name of the servo parameter.
Initial value Indicates the servo parameter initial value at factory setting.
When there is a unit in the servo parameter, the unit is shown with [ ].
Setting range Indicates the setting range of the servo parameter.
Ver. Indicates the supported firmware version of the servo amplifier. The servo parameter is available on servo amplifiers with the firmware
version or later.
Servo parameter No., symbols, and names are indicated as follows.
[Pr. PA01 Operation mode (**STY)]
Symbol
Name
No./Detail No.
