NMBA-01 ABB Modbus Adapter module
Description:
The NMBA-01 Modbus Adapter Module is an optional device for ABB drives which enables the connection of the drive to a Modbus system. The drive is considered as a slave in the Modbus network. Through the NMBA-01 Modbus Adapter Module it is possible to: 
• Give control commands to the drive (Start, Stop, Run enable, etc.) 
• Feed a motor speed or torque reference to the drive 
• Give a process actual value or a process reference to the PID controller of the drive 
• Read status information and actual values from the drive 
• Change drive parameter values 
• Reset a drive fault 
• Use Multiple Drive Control. 
The Modbus commands and services supported by the NMBA-01 Modbus Adapter Module.  
NMBA-01 is mounted onto a standard mounting rail inside or outside the drive unit, depending on drive type and configuration.
