(3) Test run and adjustment
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never make a drastic change to the parameter values as doing so will make the operation unstable.
(4) Usage
Provide an external emergency stop circuit to ensure that operation can be stopped and power switched
off immediately.
For equipment in which the moving part of the machine may collide against the load side, install a limit
switch or stopper to the end of the moving part. The machine may be damaged due to a collision.
Do not disassemble, repair, or modify the product. Otherwise, it may cause an electric shock, fire, injury,
etc. Disassembled, repaired, and/or modified products are not covered under warranty.
Use the direct drive motor with the specified servo amplifier.
Wire options and peripheral equipment, etc. correctly in the specified combination. Otherwise, it may
cause an electric shock, fire, injury, etc.
If the dynamic brake is activated at power-off, alarm occurrence, etc., do not rotate the servo motor by an
external force. Otherwise, it may cause a fire.
(5) Corrective actions
When it is assumed that a hazardous condition may occur due to a stop or product malfunction, use a
motor with an external brake to prevent the condition.
When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
After an earthquake or other natural disasters, ensure safety by checking the conditions of the
installation, mounting, wiring, and equipment before switching the power on to prevent an electric shock,
injury, or fire.
