Rockwell Automation 1336E IMPACT Adjustable Frequency AC Drive User Manual V 1-4.XX - Manual (Page 287)

Troubleshooting 12-5
For each condition that you want the drive to display a warning fault
on, you need to:
1. Set the corresponding bit in Warning Select 1.
2. Make sure the corresponding bit in Fault Select 1 is set to 0.
When the drive trips on a condition that you set to display a warning:
• The CP light flashes green.
• The drive continues to run.
If a particular bit is not set in either Fault Select 1 or Warning
Select 1, the drive ignores the condition when it occurs.
Most of the group 1 fault/warning configuration options deal with DC
bus conditions. These bus conditions deal with the bus precharge and
any type of ridethrough conditions. The bus precharge and
ridethrough conditions are covered later in this chapter.
If you are using bits 9 – 14 to ignore communication errors, please
read the following:
Configuring Faults and Warnings Group 2
You can configure which of the following faults you want to trip the
drive by using Fault Select 2 (parameter 22) and Warning Select 2
(parameter 23). Fault Select 2 and Warning Select 2 both have the
following bit definitions:
Bits 2, 7, 8, 11, 12, and 14 are reserved.
For each condition that you want the drive to fault on, you need to set
the corresponding bit in Fault Select 2. When the drive trips on a
condition that you set to fault the drive, how the drive reacts depends
on which condition occurred.

ATTENTION: Hazard of personal injury or equipment
damage exist. If you command a start or jog and then
disconnect the programming device, the drive will not
fault if you have the SCANport communications fault
set to be ignored for that port.
