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, objects, or by other means.
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.
Some servo parameters correspond to the objects that can be updated periodically in cyclic communication. For example, [Pr.
PT45 Homing method] corresponds to [Homing method (Obj. 6098h)]. When a relevant object is mapped in cyclic
communication, the controller overwrites the servo parameter value written with engineering tools. Thus, do not write a value
with the engineering tools.

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.
*: After setting, cycle the power, or reset
either the controller or the software.
**: 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.
(unit)
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)]
