Delta Electronics — 2.4 Safety precautions for using motors

ASDA-B3 Installation 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 2 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 rather than stopping the motor. Caution: 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), which is caused by the structure of brake module, not a malfunction. It will not affect the motor’s function.  When using a servo motor with a brake, do not use the 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. 2-7
