The NPBA-01
PROFIBUS Adapter
Module
The NPBA-01 PROFIBUS Adapter Module is an optional device for
ACS 600 frequency converters which enables the connection of the
ACS 600 to a PROFIBUS system. The ACS 600 frequency converter
is considered as a slave in the PROFIBUS system. Through the
NPBA-01 PROFIBUS Adapter Module it is possible to:
•
Give control commands to the drive
(Start, Stop, Direction, Run enable)
•
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.
The PROFIBUS commands supported by the ACS 600 and the
NPBA-01 PROFIBUS Adapter Module are discussed in Chapter 6.
The adapter module is mounted onto a standard mounting rail inside or
outside the converter unit, depending on converter type and
configuration.
