Modes of Operation
This chapter contains information about:
• Powering up the drive with an installed 160-DN2 DeviceNet
communication module.

.
Powering Up the Drive After you have installed the 160-DN2 module, apply power to the
drive and to the Network. The COMM LED should flash green or turn
solid green. If it does not, refer to Chapter 7
, Troubleshooting.
Modes of Operation The 160-DN2 module operating modes are:
• Power-up reset mode
• Run mode
• Error mode
Power-up Reset Mode
During power-up or reset, the COMM LED is off.
The 160-DN2 module follows this sequence of operation:
1. When power-up occurs, the COMM LED flashes green for 1/4
second, red for 1/4 second, and then goes blank while the 160-
DN2 module finishes its initialization.
2. Performs power-up initialization.
3. Reads and stores the DIP switch settings.
4. Performs a duplicate node address check to verify that another
node is not assigned the same DeviceNet address as the 160-DN2
module.
If the power-up or reset is successful, the 160-DN2 module enters the
Run mode and the COMM LED flashes green or turns solid green.
