Chapter 7 Troubleshoot the Kinetix 350 Drive
Logix5000 Controller and
Drive Behavior By using Logix Designer Application, you can configure how the Bulletin 2097
drives respond when a drive fault/exception occurs.
Kinetix 350 Drive Exception Behavior
For Kinetix 350 drives, you can configure exception behavior in RSLogix 5000
software from the Axis Properties dialog box, Actions category.
Table 57 - Kinetix 350 Drive Exception Action Definitions
TIP The I xx faults are always generated after powerup, but before the drive is
enabled, so the stopping behavior does not apply.
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
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, 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, 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 that is 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 that is defined by the drive (as in Stop Drive) and the power module is disabled.
Optionally, if the Shutdown Action attribute is configured for Drop DC Bus, the contactor
opens. An explicit Shutdown Reset is required to restore the drive to operation.
IMPORTANT The fault detection ability of TTL encoders is not as advanced as with
Stegmann hiperface or Tamagawa 17-bit serial encoders. When a TTL
encoder loses its A/B signals, the Kinetix 350 drive is unable to detect this
fault directly. Instead it relies on a secondary fault to detect the condition,
typically excessive position or velocity error. There are some cases,
particularly in Torque mode where the fault isn't detected at all. In this case,
the motor coasts to a stop, but is still enabled in Logix Designer application.
