Trial Operation
After the wiring is complete and the parameter settings have been made, conduct a trial
operation. First, check with rotation of the motor without connecting a load (i.e., without
connecting the mechanical system). Then, connect the mechanical system, auto-tune
the system, and confirm that the correct operation pattern is performed.
