Operation
Note 1. The factory setting for the speed loop proportional gain (AJ2.) is 1.0 (multiple).
Note 2. In the Adjustment Parameters Edit Mode, the set value is re-written at the point where the
number is changed by pressing the Increment Key and Decrement Key.
(2) Testing the Motor (Refer to 3-8-2 System Check Mode .)
Execute the motor test operation in System Check Mode and perform the following checks.
Is the motor's rotation direction correct?
Are there any abnormal sounds or vibration?
Is anything abnormal occurring?
(3) Checking the I/O Signal Wiring
Execute the output signal test in System Check Mode and perform the following check. (Refer to 3-8-2
System Check Mode .)
Are signals from the Position Driver being correctly read by the host controller?
Check the following item with the Check Mode's I/O signal display. (Refer to 4-2 Check Mode .)
Are signals and limit inputs from the host controller, origin proximity signals, deceleration stop input
signals, and so on, being correctly read by the Position Driver?
(4) Auto-tuning With a Load Connected (Refer to 3-9 Making Adjustments .)
Connect the motor shaft to the load (mechanical system) securely, being sure to tighten screws so that
they will not become loose.
Execute auto-tuning in System Check Mode.
(5) Turning ON the RUN Command Input
Turn ON the run command input.
Check to be sure that the motor goes into servo-lock status.
(6) Operating at Low Speed
Operate the motor at low speed.
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?
(7) Operating Under Normal Load Conditions
Operate the motor in a regular pattern and check the following items.
Is the speed correct? (Use the Monitor Mode's motor speed display and the mechanical speed
display.)
Is the load torque roughly equivalent to the measured value? (Use the Monitor Mode's motor cur-
rent display and the effective load factor 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 motor or the Driver abnormally overheating?
Is anything abnormal occurring?
