Ports to connect to on The Attendant: BUS1 – BUS4
These devices should be powered directly from the power center or breaker panel. Do not connect any wires other than Data+ and Data- to any BUS ports on The Attendant.
Wiring/Connections
Data Communication
Use two conductor 18-22AWG cable to connect the EFB (Embedded Field Bus) connector on the ACS580 drive to one of the Bus ports on The Attendant.
| ACS580 Drive | Attendant Bus Port |
| EFB Port B+ | D+ |
| EFB Port A- | D- |
Connect the cable to The Attendant as per the diagram below
Before you begin programming
Please note/record the following values from pump/motor data plates before starting programming. These are very important values that may already be configured for your pump and must be carried over into the Attendant configuration.
| Value |
| Min motor RPM |
| Max motor RPM |
| Min motor Frequency |
| Max motor Frequency |
Configuration
To control ABB ACS580 VFD drives with The Attendant you must configure the VFD to enable communication using Modbus. Settings changes on the drive are performed using the display and buttons on the unit itself. The image below depicts the display and control buttons found on all ABB ACS580 drives:
| Button | Description |
| 2 | Left Soft Key |
| 3 | Right Soft Key |
| 6 | Navigation Arrow Keys |
| 7 | Stop Button |
| 8 | Start Button |
| 9 | Local/Remote Control Key |
Configuration for Modbus Control
From the home screen press the right soft button to enter the Menu.
Scroll down to select the Parameters option and press the right soft button to Select.
Once you are inside the Parameters menu you can navigate using the up-down arrow keys (6) and the left/right soft keys (1,2). Parameters on the drive are grouped together by functional area. For example parameter group 58 is used to configure Embedded Field Bus communication. When you pick a parameter group you can scroll through all parameters available in that group. To modify a specific parameter you can highlight it with the arrow keys and then press the right soft key to “Select” it. Parameter specific choices will appear on the screen and you can make your selection. For example:
| Parameter Group | Parameter | Parameter Name | Value |
| 20 | 1 | Ext1 commands | Embedded Field Bus |
| 20 | 3 | Ext1 in1 source | Always Off |
| 20 | 4 | Ext1 in2 source | Always Off |
| 28 | 11 | Ext1 frequency ref1 | EFB ref1 |
| 58 | 1 | Protocol enable | Modbus RTU |
| 58 | 3 | Node address | 1 Set an integer address you wish to assign to the drive. This is the address you will enter into the pump configuration in the Attendant. If you are connecting more than one drive per bus port these must be unique on each drive. |
| 58 | 4 | Baud Rate | 19.2 |
| 58 | 5 | Parity | 8 NONE 1 |
| 58 | 14 | Communication Loss Action | Fault This is a very important safety setting that must be set |
| 58 | 25 | Control Profile | DCU Profile |
| 58 | 28 | EFB act1 Type | Transparent |
| 58 | 29 | EFB act2 Type | Transparent |
| 58 | 101 | Data I/O 1 | CW 16bit |
| 58 | 102 | Data I/O 2 | Ref1 16bit |
| 58 | 103 | Data I/O 3 | Ref2 16bit |
| 58 | 104 | Data I/O 4 | SW 16bit |
| 58 | 105 | Data I/O 5 | Act1 16bit |
| 58 | 106 | Data I/O 6 | Act2 16bit |
| 58 | 107 | Data I/O 7 | None |
Note:
ABB drives will occasionally require a restart/power cycle to have new settings take effect.
Set Drive Mode
ABB Drives can be operated in Local or Remote modes. In local control mode the drive is controlled directly from the keypad and will not operate using external commands sent by The Attendant. When you are finished configuring the drive settings per the Configuration for Modus Control section you must place the drive into remote mode by pressing the Loc/Rem button (9).
Please be sure your drive is in REMOTE mode if you are not able to operate the motor from The Attendant
