Lonworks is a registered trademark of Echelon Corporation. Please thoroughly read and understand the following contents to ensure correct use before operation. The content of this instruction sheet may be revised without prior notice. Please consult our distributors or
A. Introduction
Device CME-LW01 is used for communication interface between Modbus and LonTalk. CME-LW01 needs be configured via LonWorks network tool first, so that it can perform the function on LonWorks network. No need to set CME-LW01 address. This manual provides instructions for the installation and setup for CME-LW01 that is used to communicate with Delta VFD-E (firmware version of VFD-E should conform with CME-LW01 according to the table below) via LonWorks Network. The content of this instruction sheet may be revised without prior notice. Please consult our distributors or download the most updated version at http://www.delta.com.tw/industrialautomation.

These are twisted pair cables to connect to LonTalk system. Terminals 1 and 2 should be used as one group, and the same for terminals 3 and 4.
1. Check if power is 24V or plug is loose.
2. Check if flash memory IC is well-inserted to the socket.
1. Check if cable is loose.
2. Check if the communication protocol is properly set.
Check if anything wrong with power supply, clock or Neuron chip.
1. Check if anything wrong with power supply, clock or Neuron chip.
2. Check if there is a short circuit between pin 17 and
18.
If the device is not an application-less, then it could be memory problems or application code errors. A self-test failure can also turn the LED ON solid.

E. 燈號指示
CME-LW01 正面面板有三個 LED 指示燈，如下圖所示。當通訊正 常，power LED、SP LED 應是亮綠色(若紅色指示燈亮起，則表示 通訊異常)且 service LED 指示燈需是熄滅。若 LED 指示燈與上述 不同時，請參考使用手冊。
Power LED
狀態 功能描述 改善對策
綠色 LED 亮
電源正常且CME-LW01正 常運作
1. 檢查輸入電源接頭是否有鬆 脫
LED 不亮 電源或程式異常
2. 檢查 CME-LW01 的flash memory IC 是否已依 IC 座
的方向性平整的放置於 IC 座 內。

狀態 功能描述 改善對策
綠色 LED 亮
綠色 LED 閃爍
紅色 LED 亮
CME-LW01 與變頻器通訊 正常
CME-LW01 正在讀取變頻 器預設值
CME-LW01 與變頻器通訊 異常或通訊逾時
1. 檢查通訊線是否鬆脫
2. 檢查通訊格式與鮑率是否符 合 CME-LW01 之設定條件
Service LED
狀態 功能描述 改善對策
LED 以1/2 Hz 的 頻率閃爍組態 (configure)完成 後，LED 熄滅
對於一個尚未組態
(unconfigure)的 CME-LW01 而言，此乃正
常現象。CME-LW01 正常 現象
透過網路整合工具對
CME-LW01 進行組態，完成後 LED 會熄滅。
1. 檢查電源接頭與輸入規格
尚未組態
(unconfigure)， LED 即不亮
CME-LW01 硬體電路異 常
2. 檢查 CME-LW01 電路板上
的震盪器之震盪頻率是否 在 20MHz
3. 檢查神經元晶片外觀有無 損毀
1. 檢查電源接頭與輸入規格
2. 檢查 CME-LW01 電路板上
的震盪器之震盪頻率是否 LED 恆亮，即使第 一次給電亦如此。
CME-LW01 硬體電路異 常
在 20MHz
3. 檢查神經元晶片外觀有無 損毀
4. 檢查神經元晶片接腳 17、 18 之間有無短路
若非本身沒有 Application
LED 於上電初期
紅色閃爍，然後熄 滅，最後紅色 LED 恆亮。
對於一個尚未運作
(Applicationless Device)
的 CME-LW01 而言，此 乃正常現象
Image 而導致 Applicationless 的話，可能是 CME-LW01 程 式或 CME-LW01 硬體問題導 致此現象。自我測試檢查失 敗，也可能使此 LED 恆亮。
