This document describes the features and characteristics of DriveIT Low Voltage AC Drives Embedded Fieldbus (EFB) Control Modbus®, Metasys® N2, APOGEE® FLN, and BACnet® Protocols for ACH550-01/02/U1/U2 Drives.
The ABB ACH550 series are low‑voltage AC drives that can be controlled via Embedded Fieldbus (EFB) using protocols such as Modbus®, Metasys® N2, APOGEE® FLN and BACnet®. The manual provides detailed guidance on safety, mechanical and electrical installation, communication setup, and activation of drive control functions.
It also includes extensive technical data for each supported protocol, wiring recommendations (e.g., Belden 9842 cable with 120 Ω impedance), parameter settings, and troubleshooting information to help users configure, operate, and maintain the drives effectively.
| Power rating (ACH550‑01/UH) | 0.75‑90 kW (1‑150 HP) |
|---|---|
| Power rating (ACH550‑02/U2) | 110‑355 kW (150‑550 HP) |
Set parameter 9802 COMM PROTOCOL SEL to the desired value (1 = Modbus, 2 = N2, 3 = FLN, 5 = BACnet).
Use Belden 9842 or an equivalent dual‑twisted, shielded pair cable with a 120 Ω impedance.
The drive supports baud rates from 1.2 kbits/s up to 76.8 kbits/s.
Termination resistors (120 Ω) are enabled or disabled via a DIP switch at each end of the bus.
