Technical Note 096
E-Clipse bypass configuration for GP1
Siemens FLN support
The purpose of Technical Note 096 is to provide guidance for the configuration of the ACH580-01 and ACH580-31 drive
with an E-Clipse (electronic bypass) package to utilize the GP1 fieldbus. The following topics will provide guidance on
how to implement the GP1 fieldbus in support of a Siemens FLN network. This document will refer to the drive as an
ACH580 drive and the electronic bypass (RBCU) unit as an E-Clipse.
Topics:
1. GP1 introduction & ACH580 E-Clipse support of FLN
2. EIA-485 network wiring configuration for ACH580 drive and E-Clipse
3. Programming of the E-Clipse to support FLN communication
4. Point support differences between ACH550 and ACH580 drive and E-Clipse
5. FLN point support for the ACH580 drive
6. FLN point support for the ACH580 E-Clipse
Topic 1 - GP1 introduction & ACH580 support of FLN
The ACH580-01 E-Clipse and ACH580-31 E-Clipse includes the GP1 fieldbus. This generic protocol will allow the ACH580
drive and E-Clipse to communicate on a Siemens FLN network.
Just a few points on why we need to do this:
1. Siemens is moving away from the FLN protocol and has stopped issuing new application numbers for new
products, such as the ACH580.
2. There is a significant installation base of older drives on existing FLN networks. GP1 allows the ACH580 to
replace those drives.
The GP1 embedded fieldbus connection to the ACH580 drive and E-Clipse bypass is based on an industry standard RS-485
physical interface. For ease of retrofit, the ACH580 uses the same interface (Siemens 2734 application number for the drive and
Siemens 2737 application number for the E-Clipse) as the ACH550. The ACH580 supports the majority of the FLN features that
were previously supported in the ACH550. The points list for both the ACH580 and its E-Clipse bypass are included in topics 5 &
6 of this document.

Topic 2 - EIA-485 network wiring configuration for the E-Clipse bypass
All communications wiring for GP1 support for the ACH580 drive and E-Clipse is done at the RBCU.
Figure 1 EIA-485 network wiring configuration for the E-Clipse bypass.
Topic 3 - Programming of E-Clipse bypass
All programming for GP1 for FLN support for an ACH580 drive with an E-Clipse bypass is programmed at the E-Clipse
bypass control panel.

Control over the FLN Network
In the typical FLN network it is not necessary to modify any other parameters in the ACH580 Drive or E-Clipse to be able
to gather data from either the ACH580 drive or the E-Clipse bypass. If the drive was not available (failed), the points
listed in this document for the bypass would be available to the FLN network. The following parameters are only to be
modified if there is the need to start/stop the drive using the FLN network.
For run/stop over the FLN network for an ACH580 drive:
• E-Clipse bypass parameter 1601 must be set to 2: COMM
• To establish the frequency reference over the FLN network, the ACH580 drive parameter 28.11 must be set to
EFB 1.
For run/stop over the FLN network with E-Clipse to run the motor across the line:
• E-Clipse bypass parameter 1601 must be set to 2: COMM.
• E-Clipse bypass parameter 1625 must be set to 1: SYSTEM.
• E-Clipse bypass parameter 5003 must have a node ID assigned to it.
Topic 4 - Differences between FLN point support between ACH550 and ACH580 drive and E-Clipse bypass
Topic 5 & 6 includes a list of all points FLN points supported by the ACH580 drive as well as the E-Clipse bypass.
There are a few points that lack the functionality of the ACH550 and always report “0” in the ACH580 drive:
• Point 18 – Revolution counter (not supported in ACH580)
• Point 39 – Reference 2 source (only Reference 1 source bit is supported in ACH580)
• Point 48 – Maintenance trigger (not supported in ACH580)
• Point 88 – Alarm word 1 (not supported in ACH580)
• Point 89 – Alarm word 2 (not supported in ACH580)
There are a few points that lack the functionality of the 550 E-Clipse bypass and always report “0” in the ACH580 E-
Clipse bypass:
• Point 48 – Maintenance trigger (not supported in 580 E-Clipse)
• Point 88 – Alarm word 1 (not supported in 580 E-Clipse)
• Point 89 – Alarm word 2 (not supported in 580 E-Clipse)

Conclusion
This document provides the information needed to support the wiring and programming of the ACH580 E-Clipse bypass
package using native fieldbus GP1 for the support of an existing Siemens FLN network. The ACH580 drive and E-Clipse
bypass support this through the same interface (Siemens 2734 application number for the drive and Siemens 2737
application number for the E-Clipse) as the ACH550.
