Faults and Alarms Chapter 10
The list of actions that are taken can be restricted by the drive. When a previously
selected entry is no longer supported due to a configuration change, most of the
entries default to Stop Drive. In the few cases where Stop Drive does not apply,
the default is Fault Status Only. For example, Stop Drive does not apply with a
Feedback Only type configuration.

• Axis servo action is disabled
• Servo amplifier output is zeroed
• Appropriate drive enable output is deactivated
• OK contact of the servo module opens. Use this to open
the E-Stop string to the drive power supply
