ASDA-A3
 When the motor or brake is undergoing high-voltage component tests, cut off the power
supply for the controller. To maintain the product lifespan, do not perform this kind of test
unless necessary.
Operation
 AC servo motor operation is controlled by the servo drive. Do not directly connect a
commercial type power supply (100/200V, 50/60 Hz) to the servo motor circuit; otherwise
the motor cannot operate normally and may be permanently damaged.
 Follow the motor specifications when using the product. The motor's operation
temperature must not exceed the specified range.
 The material of the motor shaft is not rustproof. To ensure a longer motor life, apply
rustproof oil during operation.
 The built-in brake is for clamping, not for stopping the motor. Note that the built-in brake is
not a device for safely stopping the machine. Install another safety device for stopping the
machine. When the built-in brake is clamping the motor, rotation backlash can still occur
and the maximum rotation is 1° to 2°. When a motor with a brake is operating, the brake
lining sometimes generates a noise (a swishing or clicking sound) caused by the structure
of brake module, which is not a malfunction. It will not affect the motor's function.
 When using a servo motor with a brake, do not use the built-in brake for dynamic braking.
 If any odor, noise, smoke, heat, or abnormal vibration occurs during motor operation, stop
the motor and turn off the power immediately.
Others
 Delta servo motors have no user-replaceable parts.
 Do not disassemble the motor or change its parts, or it will void the warranty.
 Do not disassemble the motor by yourself, or it may lead to permanent malfunction or
damage.
 Do not splash any water or oil on the product.
