Shutdown
If a fault action is set to Disable Drive, then when the associated fault occurs,
axis servo action is immediately disabled, the servo output is zeroed, and the
appropriate drive enable output is deactivated. Furthermore, this fault action
opens the OK contact associated with the SERCOS module, which can be
used to open the E-Stop string to the drive power supply. Shutdown is the
most severe action to a fault and it is usually reserved for faults which 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 output is zeroed, and the
appropriate drive enable output is deactivated. Shutdown is the most severe
action to a fault and it is usually used for faults which could endanger the
machine or the operator if power is not removed as quickly as possible.
Stop Command
If a fault action is set to Stop Command, 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 SERCOS modules Drive Enable output This is the gentlest
stopping mechanism in response to a fault. It is usually used for less severe
faults, since it is relatively easy to recover from. Once the stop command fault
action has stopped the axis, no further motion can be generated until the fault
is first cleared.
