z

  Do not connect a commercial power supply to the U, V, W terminals of motor. Failure to 

observe this precaution will damage either the Servo motor or 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 and remove wiring when power is applied to the AC servo drive and 

motor.  

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. Otherwise, it may result 

in serious personnel injury. 

ASDA-B 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-B 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-B 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). 

Carefully notice 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! 

 

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 to do and if doing it may cause 
damage, malfunction and inability.
