How to Set Up BACnet Enabled ABB Variable Frequency Drives for Use With Continuum

Product Line

Andover Continuum, Other

Environment

• ABB Variable Frequency Drives
• Continuum

Cause

ABB VFDs must wired and configured properly to be used with a BACnet Continuum network.

Resolution

When wiring an ABB drive up to the Continuum BACnet MSTP network make the following connections:

Terminal X2

Type	(+)	(-)	Reference
Drive Only	29	30	31
Bypass	27	28	29

 ABB recommends that when using a two conductor cable with shield that the shields not be connected  to any pin (Note that pin 29 would be unused) but simply connected together with a wire nut. However, they do say that the shields can be connected to pin 29 if the drive communication is intermittent. 

• If the ABB drive does not have an E-Clipse bypass (E-Clipse is the ABB brand name for the bypass portion of the VFD) use the following settings:

Parameter	Setting	Notes
9802	BACNET	Sets the communications protocol of the VFD.
5302	MAC ID	Create a unique ID. A good practice is to set this to the Infinet ID + 1000. For example, if the Infinet ID is 5 then set this to 1005.
5303	Baud Rate	Set the baud rate being used on your BACnet network.
5311	Device Instance ID	This is the Infinet ID and should be set to an available number between 1-127. This will display as a hexadecimal value in the BACnet side of Cyberstation.
1001	COMM	Set this if you want to start & stop the VFD over BACnet.
1103	COMM	Set this if you want to control the drive speed over BACnet.
1604	COMM	Set this if you want to reset VFD faults over BACnet.

• If the ABB drive does include a bypass the following settings must all be entered (notice that 5302 and 5311 are now specific to the VFD portion of the unit whereas the 5002 and 5011 are specific to the bypass portion) All of these parameters as well as the parameters listed above must be entered at the bypass.

Parameter	Setting	Notes
5302	Drive MAC ID	Create a unique ID specific to the VFD.
5311	Drive Device Instance ID	This is the Infinet ID specific to the VFD.
5002	Bypass MAC ID	Create a unique ID specific to the bypass.
5011	Bypass Instance ID	This is the Infinet ID specific to the bypass.

NOTE
If the ABB drive is ACH550. Then the parameter below need to be set as a minimum. Other points will also need to be set depending on your site requirements, but the ones below will get communications up and running

Parameter	Setting	Notes
5301	x5xx	-This parameter indicates the active protocol and its revision. It should read x50xx if BACnet is properly loaded. If this is not the case, confirm that drive parameter 9802 = BACNET (5).
5302	MAC ID	-This parameter sets the drive’s BACnet MS/TP MAC ID. A temporary value of 0 places the protocol channel in reset.
5303	Baud Rate	-Set the baud rate being used on your BACnet network.
5304	Set to 0	-This parameter sets the BACnet MS/TP character format as follows: 0 = 8N1 1 = 8N2 2 = 8E1 3 = 8O1.
5311	EFB PAR 11	- Instance ID part1 This parameter, together with parameter 5317, EFB PAR 17, sets BACnet instance IDs: • For the range 1 to 65,535: This parameter sets the ID directly (5317 must be 0). For example, the following values set the ID to 49134: 5311 = 49134 and 5317 = 0. • For IDs > 65,535: The ID equals 5311’s value plus 10,000 times 5317’s value. For example, the following values set the ID to 71234: 5311 = 1234 and 5317 =7
5317	EFB PAR 17	- Instance ID part2 This parameter works with parameter 5311 to set BACnet instance IDs. See parameter 5311.
1001	COMM	-Set this if you want to start & stop the VFD over BACnet.
1103	COMM	-Set this if you want to control the drive speed over BACnet.
1604	COMM	-Set this if you want to reset VFD faults over BACnet.
