■Mode selection and permissible travel distance input
Select "Amplifier command method" in the one-touch tuning window of MR Configurator2. Input permissible travel distance of
the amplifier command method. For the fully closed loop control mode, input permissible travel distance in the load-side
resolution unit. For other control modes, input it in the servo motor-side resolution unit. In the amplifier command method, a
servo motor drives in a range between "current value ± permissible travel distance". Input the value of the permissible travel
distance as large as possible within a range that the movable part does not collide against the machine. Inputting a small
permissible travel distance decreases the possibility that the moving part collides against the machine. However, the
estimation accuracy of the load to motor inertia ratio may be lower, resulting in inaccurate tuning.
