Safety Precautions
ASDA-A3 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-A3 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 severe 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
Installation
Wiring
Please follow the instructions when using the A3 servo drive and servo motor, or it may cause
fire or malfunction.
Do not expose the product to an environment containing water, corrosive gas, inflammable
gas...etc., or it may result in electric shock or fire.
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.
Please tighten the screws of the power and motor output terminals, or it may cause fire.
Please refer to description of wire selection in Chapter 3 to prevent any danger.
