PrefaceASDA-A2R Series
ii Revision December, 2014
Safety Precautions
ASDA-A2R series is the high resolution and open type servo drive. It should be installed in
a shielded control box during operation. This servo drive uses precise feedback control and
the digital signal processor with high-speed calculation function to control the current output
which generated by IGBT so as to operate three-phase permanent magnet synchronous
motors (PMSM) and to achieve precise positioning.
ASDA-A2R is applicable on industrial application and is suggested to be installed in the
panel-board of the user manual. (Servo drives, wire rod and motors all should be installed
in the environment which complies with the minimum requirement of UL Level 1.)
Pay special attention to the following safety precautions anytime during inspection,
installation, wiring, operation and examination.
The symbol of danger, warning and stop represent:
It indicates the potential hazards. It is possible to cause severe injury or fatal
harm if not follow the instructions.
It indicates the potential hazards. It is possible to cause minor injury or lead to
serious damage of the product or even malfunction if not follow the instructions.
It indicates the absolute prohibited activity. It is possible to damage the product or
cannot be used due to malfunction if not follow the instructions.
Inspection
Please follow the instruction when using servo drive and servo motor, or it is
possible to cause fire or malfunction.
Installation
It is prohibited to expose the product with the environment which containing
water, corrosive gas, inflammable gas, etc. Or it is possible to cause electric
shock or fire.
Wiring
Please connect the ground terminal to class-3 ground system (under 100 Ω),
poor grounding may result in electric shock or fire.
Do not connect the three-phase source to the motor output terminal U, V and
W. Or it is possible to cause personnel injury or fire.
Please tighten the screws of the power and motor output terminal. Or it is
possible to cause fire.
Please connect wiring according to the wire rod in order to prevent any
danger.
