Current Processor Faults & Warnings – Both the fault and warning
queues are configurable for either the Current or the Velocity processor.
You can configure which Current processor faults you want to trip the
Drive by setting Parameter 86. When the Drive trips on one of the faults
set in parameter 86, the CP light on the Main Control board will turn red.
When the drive trips, it will coast the motor to a stop. Parameter 87 has
the same bit definitions as parameter 86, but instead of tripping, the Drive
will display a warning fault, which in turn causes the CP light to flash
green, indicating a warning. The Drive will continue to run when there is a
CP warning. Parameter 82 displays which CP fault caused the Drive to
trip, while parameter 84 displays any CP warnings that have occurred.
Most of the setup for the current processor Fault/Warning configuration
deals with DC Bus conditions. These Bus conditions deal with the Bus
precharge and any type of ride through conditions.
Configuring CP Faults and Warnings – You can configure which of the
following faults you want to trip the drive by using CP Fault/Warning
Configuration Select (parameter 86) and CP Warning/None Configuration
Select (parameter 87). Parameters 86 and 87 both have the following bit
definitions:
This
bit:
With this text: Is defined as:
0 RidethruTime A bus ridethrough timeout occurred.
1 Prechrg Time A precharge timeout occurred.
2 Bus Drop
A bus voltage drop of 150V below the bus tracker
voltage. This is covered in detail later in this
chapter.
3 Bus Undervlt
A bus voltage drop to a level below the value set
in Undervoltage Setpoint (parameter 224).
4 Bus Cycles>5
More than 5 ridethroughs occurred within a 20
second period.
5 Open Circuit
The fast flux up current is less than 50% of
commanded.
6–15 RESERVED, Always leave zero.
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.
