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: 1. Function availability differs for drive models CIMR-A4A0930 and 4A1200. Refer to Parameter Differences for models
CIMR-A
for details.
2. Refer to Application Selection on page 114 to set up the drive using one of the application presets.
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 set
tings in simple applications that do not require high precision.
Figure 4.7
Figure 4.8 Basic Start-up
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-T
uning should be performed again after installing an AC reactor or other such components to the output side of the drive.
