Warning — Risk of damage and/or personal injury When testing the
installation of drives, use safe methods suitable for your particular
application.
Replacing a Unit in the Network
If you need to replace a drive, do the following:
1. Remove the old unit from the network.
2. Connect the new drive to a PC that is not part of the multi-drop network.
3. Apply power to the drive.
4. Using terminal emulation software, send the following command—
Ø_ADDRi (where i is the address you want to assign the new unit).
5. If you can communicate with the old drive, upload its configuration using
the Aries Support Tool. Alternatively, you can create a new configuration
file using the Aries Support Tool. Then download the configuration file to
the new drive.
6. Remove power to the drive. The drive can now be installed in the multi-
drop network.
Sending Commands to a Specific Unit
You can send ASCII commands from the master unit (for example a personal
computer, PLC, or controller) to a specific unit in the multi-drop network.
Prefix the command with the unit address and an underscore (_). For
example, 3_ERES4ØØØ sets the encoder resolution to 4000 for unit 3. The
master unit can receive data from any unit in the network.
Note: Make sure you can access each unit on the network. See “Setting up
Drives for a Multi-Drop Network” on page 76.
RS-232/485 Dongle for Communications Setup The Aries Dongle is a Y-cable (part number 71-021609-01) that breaks out
the RS-232/485 portion of the DRIVE I/O cable so that you may simultaneously
communicate with the Aries Drive while it is also connected with a motion
controller.
Note: When using the Aries Dongle, you must use a null-modem (cross-
over) cable between your PC and the Aries drive
Caution — The dongle is designed for setup and troubleshooting purposes
only. Do not use the dongle in a permanent installation; it does not meet
EMC requirements.
