7. Press the DATA Key again to return to the parameter number display.
(2) Jog Operations (See
3-6-2 Jog Operations.)
•
Perform jog operations using the Parameter Unit and confirm the following:
Does the motor turn in the correct direction?
Is there any unusual sound or vibration?
Do any error occur?
•
If an error occurs, refer to
Chapter 4 Application for troubleshooting.
(3) Connect a load and auto-tune (See
3-7 Making Adjustments.)
•
Connect the motor shaft to the load (mechanical system) securely, being sure to tighten screws so that
they will not become loose.
•
Perform auto-tuning with the Parameter Unit.
(4) Turning ON the Run command Input
•
Turn ON the run command input. The Servomotor will go into servo-ON status.
•
Give a speed command, or carry out the following check with a jogging operation.
(5) Low Speed Operation
•
Operate at low speed.
Apply a low-frequency pulse command.
The meaning of “low speed” can vary with the mechanical system. Here, “low speed” means approxi-
mately 10% to 20% of the actual 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 anything abnormal occurring?
•
If anything abnormal occurs, refer to
Chapter 4 Application and apply the appropriate countermea-
sures.
(6) Operation Under Actual Load Conditions
•
Operate the Servomotor in a regular pattern and check the following items.
Is the speed correct? (Use the speed display.)
Is the load torque roughly equivalent to the measured value? (Use the torque command display.)
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 anything abnormal occurring?
•
If anything abnormal occurs, refer to
Chapter 4 Application and apply the appropriate countermea-
sures.
(7) Readjust the gain.
•
If the gain could not be adjusted completely using auto-tuning, perform the procedure in
3-7 Making
Adjustments to adjust the gain.
