Introduction
This manual provides information about the PROFIBUS
Communications module (MDCOMM-PBUS) and using it with
MD65 drives. It is intended for qualified electrical personnel familiar
with installing, programming, and maintaining AC drives and
networks.
The PROFIBUS

module is an embedded communication option
for MDI

AC drives, such as the MD65

drive. The module is
mounted in the drive and receives its required power from the drive.
The module can be used with other products that implement MDI, a
peripheral communication interface. Refer to the documentation for
your product for specific information about how it works with the
module.
1.1 PROFIBUS Module Features
The PROFIBUS module features the following:
• The low seven bits of 8-bit DIP switch let you set a node address,
and the MSB bit provides write access for the Flash update of
module firmware.
• Depending on the jumper position, “1X” or “5X”, the two operation
modes “Single” and “Multiple” are supported:
• In Single Drive Mode (default mode), the module
represents a single drive on one node and can support
one external peripheral (for example, an OIM) over MDI.
• In Multi-Drive Mode, the module represents up to 5 drives
on one node daisy-chained over the RS-485 interface. In
this case, the unit will not operate with MDI peripheral
devices such as the OIM or the MDCOMM-232.
• Status indicators that report the status of the drive
communications, module, and network.
• The I/O messages (i.e. Control/Status, Reference/Feedback) will
be exchanged with Profibus master in every bus cycle. I/O
configuration is fixed and Datalinks are not supported.
• The slave device’s parameters on the PROFIBUS network can be
configured and monitored using explicit messaging.
