Introduction
This manual provides information about the RS485 DF1
Communications module (RECOMM-485) and using it with DPI

AC drives, such as SP600 drives. It is intended for qualified
electrical personnel familiar with installing, programming, and
maintaining AC drives and networks.
The RS485 DF1 Communications module allows an RS485 DF1
Master device to access the SP600 drive using:
• Logic Command/Reference (Start, Stop, Reference, etc.)
• Logic Status Feedback
• Datalinks A-D
• Explicit Messages
It also allows VS Utilities configuration software (version 1.01 or
higher) to connect to an SP600 drive using a Serial Converter
module (RECOMM-232) and communicate with other SP600 drives
using an RS485 connection.
The module is mounted in the drive and receives its required power
from the drive. It can be used with other products that implement
DPI, which is a peripheral communication interface. Refer to the
documentation for your product for specific information about how it
works with this module.
1.1 Module Features
The RS485 DF1 Communications module features the following:
• Switches that enable you to set a node address and network data
rate before applying power to the drive. Alternatively, you can
disable these switches and use parameters to configure these
features.
• Status indicators that report the status of the drive
communications, module, and network. They are visible both
when the cover is opened and when it is closed.
• I/O, including Logic Command/Reference and up to four pairs of
Datalinks that may be configured for your application using a
parameter.
