Troubleshooting
Configuring Faults and Warnings Group 1
You can configure which of the following faults you want to trip the
drive by using Fault Select 1 (parameter 20) and Warning Select 1
(parameter 21). Fault Select 1 and Warning Select 1 both have the
following bit definitions:
Bits 6 and 7 are reserved.
For each condition that you want the drive to fault on, set the
corresponding bit in Fault Select 1. When the drive trips on a
condition that you set to fault the drive, how the drive reacts depends
on which condition occurred.
For bits 0 through 5:
•
The red CP light turns on.
•
The motor coasts to a stop.
For bits 8 through 14:
•
The red VP light turns on.
•
The motor stops according to how bits 1 – 3 in Logic Options
(parameter 17) are set.
