No-Load Operation Test Run
This section explains how to operate the drive with the motor decoupled from the load during a test run.
■
Before Starting the Motor
Check the following items before operation:
• Ensure the area around the motor is safe.
• Ensure external emergency stop circuitry is working properly and other safety precautions have been taken.
■
During Operation
Check the following items during operation:
• The motor should rotate smoothly (i.e., no abnormal noise or oscillation).
• The motor should accelerate and decelerate smoothly.

No-Load Operation Instructions
The following example illustrates a test run procedure using the digital operator.
Note:
Before starting the motor, set the frequency reference d1-01 to 6 Hz.
Operating Procedure
LCD Display
1
The control power supply is powered up. The initial display will appear.
2
Press the
key to select LOCAL.
The LO/RE light will turn on.
3
Press
to give the drive a Run command.
RUN will light and the motor will rotate at 6 Hz.
4
Ensure the motor is rotating in the correct direction and that no faults or alarms
occur.
5
If there is no error in step 4, press
to increase the frequency reference.
Increase the frequency in increments of 10 Hz, verifying smooth operation at all
speeds. For each frequency, check the drive output current using monitor U1-03.
The current should be well below the motor rated current.
Example: 6 Hz
→
60 Hz
