Overview

The PROFIBUS-DP communication module allows the LSLV-G100 inverter to connect to a PROFIBUS network.

What is the PROFIBUS-DP Communication Module?

Using the network features, controlling and monitoring of the inverter can be performed via a PLC sequence program or a master device. Because multiple inverters can be operated with one communication cable, this reduces the total installation cost. In addition, installation time is reduced and easy maintenance is made available because installation and routing of cables has become simpler. Factory automation can also be easily implemented by linking various auxiliary devices with a PLC and by utilizing other control systems, such as a PC, for controlling the inverter.

Set drv parameter (Cmd Source) to "4 (Fieldbus)" using the keypad to operate the G100 Inverter via the PROFIBUS-DP communication board. Set Frq parameter (Frq Ref Src) to “8(Fieldbus)” using the keypad to provide frequency reference via the PROFIBUS-DP communication board.

PROFIBUS-DP Communication Parameter List

Inverter Parameters

Communication module Version

CM-06 is used to display the version of PROFIBUS-DP communication module installed on the inverter.

Station ID Setting

The following parameters are used to set the Station ID for the PROFIBUS-DP communication module:

• CM-07: FBus ID
• CM-94: Comm Update

The parameters above are used to set the Station ID for the PROFIBUS-DP communication module. A Station ID can be set to a value within a range of 1–125. The station ID cannot be duplicated. Make sure the same Station ID is not used by another module in the network. After changing the Station ID, you must set "CM-94 (Comm Update)" to "1" to apply the change to the PROFIBUS-DP Communication module.

LED Indication for Communication Status

CM-09 is used to indicate the operation status of the three LED indicators (NODE, ERROR, CPU) on the PROFIBUS-DP communication module. On the keypad display, the status of the 3 LED indicators are displayed, in an order of blank (reserved), NODE, ERROR, and CPU, from left to right.

(Example of an LED indicator status expressed with CM-09)

[Diagram showing digital displays representing LED status: Reserved (OFF), NODE (GREEN ON), ERROR (RED OFF), CPU (GREEN ON).]

Number of Para Status settings

The parameters above are used to determine how much "Para Status" data will be sent to the master device by the inverter through PROFIBUS-DP network communication. The number of the "Para Status" can be set to a number between 0 and 8. After setting the number of "Para Status," each "Para Status" has to be set using the matching number of parameters from CM-31 to CM-38. For example, if CM-30 is set to "3," "Para Status" should be set for CM-31 to CM-33. If CM-30 is set to "6," the "Para Status" should be set for CM-31 to CM-36. After changing the number of "Para Status," you must set "CM-94 (Comm Update)" to "1" to apply the changes to the PROFIBUS-DP communication module.

Para Status 1–8

The following parameters are used to set the Station ID for the PROFIBUS-DP communication module:

The "Para Status" setting defines which status information will be sent to the master device through PROFIBUS-DP network communication. Para Status 1–8 are set in the form of inverter address. The inverter's common area and keypad parameter addresses are used as the setting values. The keypad parameter addresses can be expressed according to the following formula: 0x1000 + ("Group number" x 0x100) + ("Code number"). For example, if you want to set "Para Status1" to "In.90 (DI Status)," you can set it as an address, "0x155A." (0x1000 + 0x05 x 0x100 + 0x5A (Dec 90) = 0x155A)

Number of Para Control settings

The parameters above are used to determine how much "Para Control" data will be sent to the master device by the inverter through PROFIBUS-DP network communication. The number of the "Para Control" can be set to a number between 0 and 8. After setting the number of "Para Control", each "Para Control" has to be set using the matching number of parameters from CM-51 to CM-58. For example, if CM-50 is set to "2," "Para Control" should be set for CM-51 to CM-52. If CM-50 is set to "5," the "Para Status" should be set for CM-51 to CM-55. After changing the number of "Para Control," you must set "CM-94 (Comm Update)" to "1" to apply the changes to the PROFIBUS-DP communication module.

Para Control 1–8

The "Para Control" setting defines which control information will be sent to the master device through PROFIBUS-DP network communication. Para Control 1-8 are set in the form of an inverter address. The inverter's common area and keypad parameter addresses are used as the setting values. The keypad parameter addresses can be expressed according to the following formula: 0x1000 + ("Group number" x 0x100) + ("Code number"). For example, if you want to set the jog frequency set "Para Control 1" to "dr-11 (Jog frequency)," you can set it as an address, "0x110B." (0x1000 + 0x01 x 0x100 + 0x0B (Dec 11) = 0x110B)

Comm Update

After changing the Station ID, and the number of Para Status and Para Control, set the "CM-94 (Comm Update)" to "1" to apply the changes to the PROFIBUS-DP communication module. The changes will be applied to the PROFIBUS-DP communication module automatically even if you do not set the "CM-94 (Comm Update)" to "1", and the new setting values will be applied to the PROFIBUS-DP communication module again when "CM-94 (Comm Update)" is set to "1."

Setting PROFIBUS Bit Swap

You can set whether the LSB and MSB bits in the data transmitted during network communication will be swapped. (This setting is required if the upper-level controller has an interface that reads the LSB and MSB data from the PROFIBUS communication module in a reverse order.)

GSD File (Electronic Data Sheets)

A GSD file includes information about the PROFIBUS-DP communication module. The GSD file is required to utilize the PROFIBUS Configuration Software. You can download the GSD file from the technical support page of LS ELECTRIC website (https://www.lselectric.co.kr).
