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.
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.
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.
