大功率抑制電路

DVP-ES2/EX2系列PLC之電晶體輸出均已包含反電勢保護之二極體，對於小功率電感性負載 且ON/OFF頻率不高之應用已足夠，但在大功率或ON/OFF頻繁之場合，請依下列方法另接抑制電路以降低雜訊干擾及防止過電壓或過熱而損壞電晶體輸出電路。

因電晶體模組輸出均為開集極輸出 (Open Collector)，若Y0/Y1設定為脈波串輸出，為確保電晶體模組能夠動作正常，其輸出提升電阻必須維持輸出電流大於0.1A。

Delta’s ASDA Series AC Servo System and Coil Winding Machine

[Introduction] 
There are many daily applications that use coils, such as the pickup head of a DVD player, power supplies,
electronic transformers, switching transformers and motors. In particular, applications for motors are various and many.
 The vehicle industry is a typical example, where just one luxury vehicle requires almost 150 motors. The
requirements for motors are also very high.
In general, a motor has a stator and a rotor.
The stator is a stationary element, and the rotor is a rotating element.
A stator comprises plural stacked silicon steel plates wrapped in several sets of tightly-wound copper wires called coils.
The coil’s winding is critical in the manufacturing process of stator construction and also very important for the quality of the motor.
There are many kinds of coil winding machines for the manufacturing of many types of stators.
For coil winding machine applications, Delta provides high-resolution servo systems to facilitate the high-speed and high-precision winding process.

[Functions] 
Typically, a coil winding machine includes at least one XYZ moveable table and one high-speed rotatable spindle axis.
With single-axis point to point motion commands, the XYZ moveable table moves the motor stator to the working position where copper wires are fastened, wound and cut.
 To complete the winding automatically, the XYZ moveable table fastens the head of the copper wire on fixed pins.
The spindle axis adopts Delta’s servo systems which carry a feeder, supply copper wires, and wrap the stacked silicon steel plates in several sets of tightly-wound copper wires.
After the winding is complete, Delta’s servo systems help the system to stop precisely at the working position and ensure the copper wires are coupled and not released.
With increased winding speed production capability is enhanced substantially.

台達交流伺服A2應用於環型馬達繞線機

【基本介紹】
生活中許多電子產品都會運用到線圈，
如: DVD讀寫頭線圈、電源供應器、電子變壓器、開關電源變壓器和馬達，
尤其是馬達的運用更是多元化，一台高級汽車中可能用到將近150顆的馬達，
而馬達的製造，就要從矽鋼片的繞線開始。馬達的定子型態相當多種，
此應用案例為一環型定子的繞線機，搭配台達高解析度伺服馬達來達到高速高精度的生產。

【設備功能】
繞線機設備主要包含一 XYZ 移動平台和一高速繞線組軸，
XYZ 平台通常大多皆使用單軸點對點運動指令來實現，
在機台中使用為將未繞線的馬達定子移動到機台工作區的功能，
並在繞線完畢將線頭纏繞在固定的 PIN 上，來達成自動理線功能。
繞線過程中除了將銅線纏繞在矽鋼片上，還需要將線排列整齊，避免銅線凸出線槽。
繞線主軸採用伺服馬達，能夠精確的掌控停止位置，讓排線整齊，轉速快提昇產能。


【台達提供系統解決對策】
台達交流伺服系統主要特性:
(1)具有多種控制模式，可與各種上位控制器連結使用，使用廣泛。
(2)具有速度、位置迴路的平滑常數功能，能有效對輸入訊號作平滑化處理。
(3)強健式的控制模式，在負載慣量大的範圍變化時，系統仍然可以保持優異的性能。
(4)強大的高頻共振及低頻擺振抑制功能，能有效改善共振及低頻抖動現象。
(5)優異的命令追隨性能，伺服響應頻率達 1KH，能快速反應命令的變化達到幾乎無延遲的動作。
(6)豐富且完整的軟體操作功能，方便使用者快速調整伺服系統性能。
(7)ASDA-A2 馬達編碼器解析度可達 1280000PPR，B2 馬達編碼器解析度可達 160000PPR，位置控制更精確，動作更平順。
