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.

E. LEDs Indications 
There are three LEDs in front panel of CME-LW01. If the 
communication is normal, power LED, SP LED should be green 
(red LED means abnormal communication) and service LED 
should be OFF. If LEDs display do not match, refer to user 
manual for details.

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。
