Safety Precautions ASDA-B3 is a high resolution, open type servo drive. It should be installed in a shielded control box during operation. This product uses precise feedback control and a digital signal processor (DSP) with high-speed calculation functions to control the current output generated by IGBT to operate three-phase permanent magnet synchronous motors (PMSM) and to achieve precise positioning. The ASDA-B3 series are used in industrial applications and should be installed in the control box. Servo drives, wires, and motors should all be installed in an environment which complies with the minimum requirement of UL50 Type 1.
Pay special attention to the following safety precautions at all times during inspection, installation, wiring, operation, maintenance, and examination of the servo drive. The symbols of “DANGER”, “WARNING”, and “STOP” indicate: Danger. May cause severe or fatal injuries to personnel if the instructions are not followed. Warning. May cause moderate injury to personnel, or lead to several damage or even malfunction of the product if the instructions are not followed. Absolutely prohibited activities. May cause serious damage or even malfunction of the product if the instructions are not followed.
Inspection Follow the instructions when using the B3 servo drive and servo motor, or it may cause fire or malfunction. Installation Do not expose the product to an environment containing vapor, corrosive gas, inflammable gas, or other foreign matter to reduce the risk of electric shock or fire. Wiring Connect the ground terminals to class-3 ground system. Ground resistance should not exceed 100 Ω. Improper grounding may result in electric shock or fire. Do not connect the three-phase source to the motor output terminals U, V, and W, or it may cause personnel injury or fire. Tighten the screws of the power and motor output terminals, or it may cause fire.
When wiring, refer to the description of wire selection in Chapter 3 to prevent any danger. ii
