Start-Up Flowcharts

The flowcharts in this section summarize basic steps required to start the drive. Use the flowcharts to determine the most
appropriate start-up method for a given application. The charts are intended as a quick reference to help familiarize the
user with start-up procedures.

application. Use drive default parameter settings in simple applications that do not require high precision.

Note: 1. When the motor cable length has changed for more than 50 m after Auto-Tuning has been performed (e.g., after the drive has been set
up and then later installed in a different location), execute Stationary Auto-Tuning for resistance between motor lines once the drive
is installed in its final installation location.
2. Auto-Tuning should be performed again after installing an AC reactor or other such components to the output side of the drive.
