Starting Conditions - Mitsubishi Electric MELSEC iQ-R Series User Manual

Starting conditions

To start the control, the following conditions must be satisfied.
The necessary conditions must be incorporated in the program so that the axis is not started when the conditions are not
satisfied.
Starting conditions of the axis are mainly controlled by the state transition and the signal state of the axis and axes group.
