4.4 Start-Up Flowcharts
4.4 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.
Note: To set up the drive using one of the Application Presets, refer to Application Selection on page 103.
◆ Flowchart A: Basic Start-up and Motor Tuning
Flowchart A in Figure 4.8 describes a basic start-up sequence. This sequence varies slightly depending on the
application. Use drive default parameter settings in simple applications that do not require high precision.

Figure 4.8 Basic Start-up
Note: 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.
Note: Auto-Tuning should be performed again after installing an AC reactor or other such components to the output side of the drive.
