z
Do not connect commercial power to the U, V, W terminals. Failure to observe
this precaution will cause severe damage to the Servo drive.
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

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-B2 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-B2 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-B2 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.
