DA180 series basic AC servo drive
P1.03 Mechanical rigidity
A greater mechanical rigidity value indicates quicker response and high rigidity performance, but it
increases the possibility to cause vibration. In stable working condition, you can set a greater value
to obtain quicker response.

Modbus address
P1.04* Tune inertia offline
This parameter is used to obtain the load inertial ratio of the motor rotation inertia. After inertia
identifying is enabled, the motor runs six cycles to identify inertia. In each cycle, the motor runs at
the mode specified by P1.05 [Inertia identifying mode]. The maximum rotation number of the motor
is determined by P1.06 [Max. rotations by inertia identifying], and the ACC command time is
determined by P1.07 [ACC time for inertia identifying].
Setting
[0]
Note:
 The motor speed is fast during identifying if P1.06 and P1.07 are set to great values.
 If the drive reports the alarm Er25-7 during identifying, see section 9.1 "Servo drive faults and
workarounds" to handle it.
 This parameter is invalid when the servo is enabled.
