164 Naming & Configuring Your Motion Axis
Select one of the following fault actions for each fault type:
• Shutdown - If a fault action is set to Shutdown, then when the
associated fault occurs, axis servo action is immediately disabled, the
servo amplifier output is zeroed, and the appropriate drive enable
output is deactivated. Shutdown is the most severe action to a fault and
it is usually reserved for faults that could endanger the machine or the
operator if power is not removed as quickly and completely as possible.
• Disable Drive - If a fault action is set to Disable Drive, then when the
associated fault occurs, axis servo action is immediately disabled, the
servo amplifier output is zeroed, and the appropriate drive enable
output is deactivated.
• Stop Motion - If a fault action is set to Stop Motion, then when the
associated fault occurs, the axis immediately starts decelerating the axis
command position to a stop at the configured Maximum Deceleration
Rate without disabling servo action or the servo modules Drive Enable
output. This is the gentlest stopping mechanism in response to a fault. It
is usually used for less severe faults. After the stop command fault action
has stopped the axis, no further motion can be generated until the fault
is first cleared.
• Status Only - If a fault action is set to Status Only, then when the
associated fault occurs, no action is taken. The application program
must handle any motion faults. In general, this setting should only be
used in applications where the standard fault actions are not appropriate.
Drive Fault
Specifies the fault action to be taken when a drive fault condition is detected,
for an axis with the Drive Fault Input enabled (in the Servo tab of this dialog)
that is configured as Servo (in the General tab of this dialog). The available
actions for this fault are Shutdown and Disable Drive.
Feedback Noise
Specifies the fault action to be taken when excessive feedback noise is
detected. The available actions for this fault are Shutdown, Disable Drive, Stop
Motion and Status Only.
ATTENTION
!
Selecting the wrong fault action for your application can
cause a dangerous condition resulting in unexpected
motion, damage to the equipment, and physical injury or
death. Keep clear of moving machinery.
