Troubleshoot the Kinetix 5700 Drive System
Logix5000 Controller and
Drive Module Behavior
By using the Logix Designer application, you can configure how the
Kinetix 5700 system responds when a module fault/exception occurs.
The DC-bus power supplies and servo drives support fault actions for Ignore,
Alarm, Minor Fault, and Major Fault as defined in
. The drives also
support five configurable stopping actions as defined in
Table 107 - Kinetix 5700 Module Exception Action Definitions
You can configure exception behavior in the Logix Designer application from
the Axis Properties dialog box, Actions category. These controller exception
actions are mapped to the drive exception actions.
Table 108 - Logix Designer Exception Action Definitions
TIP
The INIT FLT
xxx
faults are always generated after powerup, but before the drive is
enabled, so the stopping behavior does not apply.
NODE ALARM
xxx
faults do not apply because they do not trigger stopping behavior.
For troubleshooting SAFE FLT fault codes, refer to
(hardwired
safety) or
(integrated safety).
The iTRAK power supply cannot be configured by using the Studio 5000 Logix
Designer application, but the pre-configured faults are shown on
Exception Action
Definition
Ignore
The drive module completely ignores the exception condition. For some exceptions that are
fundamental to the operation of the planner, Ignore is not an available option.
Alarm
The drive module sets the associated bit in the Motion Alarm Status word, but does not
otherwise affect axis behavior. Like Ignore, if the exception is so fundamental to the drive,
Alarm is not an available option. When an exception action is set to Alarm, the Alarm goes
away by itself when the exceptional condition has cleared.
Minor Fault
The drive module latches the exception condition, but the drive does not execute any
exception action.
Major Fault
The drive module latches the exception condition and executes the configured exception
action.
Exception Action
Definition
Ignore
The controller completely ignores the exception condition. For some exceptions that are fundamental to the
operation of the planner, Ignore is not an available option.
Alarm
The controller sets the associated bit in the Motion Alarm Status word, but does not otherwise affect axis behavior.
Like Ignore, if the exception is so fundamental to the drive, Alarm is not an available option. When an exception
action is set to Alarm, the Alarm goes away by itself when the exceptional condition has cleared.
Fault Status Only
Like Alarm, Fault Status Only instructs the controller to set the associated bit in the Motion Fault Status word, but
does not otherwise affect axis behavior. However, unlike Alarm an explicit Fault Reset is required to clear the fault
once the exceptional condition has cleared. Like Ignore and Alarm, if the exception is so fundamental to the drive,
Fault Status Only is not an available option.
Stop Planner
The controller sets the associated bit in the Motion Fault Status word and instructs the Motion Planner to perform a
controlled stop of all planned motion at the configured maximum deceleration rate. An explicit Fault Reset is
required to clear the fault once the exceptional condition has cleared. If the exception is so fundamental to the drive,
Stop Planner is not an available option.
Stop Drive
When the exception occurs, the associated bit in the Fault Status word is set and the axis comes to a stop by using
the stopping action defined by the drive for the particular exception that occurred. There is no controller based
configuration to specify what the stopping action is, the stopping action is device dependent.
Shutdown
When the exception occurs, the drive brings the motor to a stop by using the stopping action defined by the drive
(as in Stop Drive) and the power module is disabled. An explicit Shutdown Reset is required to restore the drive to
operation.
