Preface|ASDA-AB Series
ii
Revision January 2009
z Ensure that the motor and drive are correctly connected to a ground. The grounding
method must comply with the electrical standard of the country (Please refer to NFPA 70:
National Electrical Code, 2005 Ed.).
z Do not disconnect the AC servo drive and motor while the power is ON.
z Do not attach, modify or remove wiring while power is applied to the AC servo drive.
z Before starting the operation with a mechanical system connected, make sure the
emergency stop equipment can be energized and work at any time.
z Do not touch the drive heat sink or the servo motor during operation, this may cause
serious personnel injury.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
Carefully note and observe the following safety precautions when receiving, inspecting, installing, operating,
maintaining and troubleshooting. The following words, DANGER, WARNING and STOP are used to mark
safety precautions when using the Delta’s servo product. Failure to observe these precautions may void
the warranty!
ASDA-AB series drives are open type servo drives and must be installed in an NEMA enclosure such as a
protection control panel during operation to comply with the requirements of the international safety
standards. They are provided with precise feedback control and high-speed calculation function
incorporating DSP (Digital Signal Processor) technology, and intended to drive three-phase permanent
magnet synchronous motors (PMSM) to achieve precise positioning by means of accurate current output
generated by IGBT (Insulated Gate Bipolar Transistor).
ASDA-AB series drives can be used in industrial applications and for installation in an end-use enclosure that
do not exceed the specifications defined in the ASDA-AB series user manual (Drives, cables and motors are
for use in a suitable enclosure with a minimum of a UL50 type 1 or NEMA 250 Type 1 rating).
The words, DANGER, WARNING and STOP, have the following meaning:
Indicates a potentially hazardous situation and if not avoided, may result in serious injury
or death.
Indicates a potentially hazardous situation and if not avoided, may result in minor to
moderate injury or serious damage to the product.
Indicates an improper action that it is not recommended. Doing so may cause damage or
malfunction.
Unpacking Check
¾ Please ensure that both the servo drive and motor are correctly matched for size (power rating). Failure to observe this
precaution may cause fire, seriously damage to the drive / motor or cause personal injury.
Installation
¾ Do not install the product in a location that is outside the stated specification for the drive and motor. Failure to observe this
caution may result in electric shock, fire, or personal injury.
