4.5 Powering Up the Drive 4.5 Powering Up the Drive u Powering Up the Drive and Operation Status Display n Powering Up the Drive Review the following checklist before turning the power on. n Status Display When the power supply to the drive is turned on, the LED operator lights will appear as follows: Setting the V/f pattern according to the application. Refer to E: Motor Parameters on page 86 for details on setting the V/f pattern. n Notes when Setting the V/f Pattern Set the maximum output frequency to match the motor characteristics. If the V/f pattern voltage is increased motor torque may also increase. However, if the V/f voltage is set too high these problems may occur:
• Excessive motor current. • Motor overheat or vibration.
