Operation
Turning OFF the Servomotor
In order that the Servomotor can be immediately turned OFF if an abnormality occurs in the machinery,
set up the system so that the power and the RUN command can be turned OFF.
H Trial Operation
1. Turn ON the Power Supply.
• Turn ON the power supply to the control circuits and main circuits, and then turn ON the RUN
command.
• Check that the Servomotor is ON.
2. Low-speed Operation
• Send a low speed command from the host controller to rotate the Servomotor. (The definition of
low speed varies depending on the mechanical system, but a rough estimate is 1/10 to 1/5 nor-
mal operating speed.)
• Check the following items.
Is the emergency stop operating correctly?
Are the limit switches operating correctly?
Is the operating direction of the machinery correct?
Are the operating sequences correct?
Are there any abnormal sounds or vibration?
Is any error (or alarm) generated?
Note 1. If anything abnormal occurs, refer to Chapter Troubleshooting and apply the appropriate
countermeasures.
Note 2. If the system vibrates due to insufficient gain adjustment, making it difficult to check the opera-
tion, refer to 4-7 Making Adjustments, and adjust the gain.
3. Operation Under Actual Load Conditions
• Operate the Servomotor in a regular pattern and check the following items.
Is the operating speed correct? (Use the speed feedback monitor.)
Is the load torque roughly equivalent to the measured value? (Use the torque command monitor and
the accumulated load monitor.)
Are the positioning points correct?
When an operation is repeated, is there any discrepancy in positioning?
Are there any abnormal sounds or vibration?
Is either the Servomotor or the Servo Driver abnormally overheating?
Is any error (or alarm) generated?
Note 1. Refer to 4-9-3 Monitor Mode for how to display the speed feedback monitor, torque command
monitor, and the cumulative load rate monitor.
Note 2. If anything abnormal occurs, refer to Troubleshooting and apply the appropriate countermea-
sures.
Note 3. If the system vibrates due to insufficient gain adjustment impeding, making it difficult to check
the operation, refer to 4-7 Making Adjustments, and adjust the gain.
4. Completing the Trial Operation
• Performing the above completes the trial operation. Next, adjust the gain to improve command
efficiency. (Refer to 4-7 Making Adjustments for details.)
