Auto Restart (Reset/Run)

7. If a terminal has Manual control and clears its DPI reference mask (disallows
reference ownership), then Manual control will be released. By extension, if
the drive is configured such that the HIM can not select the reference (via
reference mask setting), then the drive will not allow the terminal to acquire
Manual control.
8. If a terminal has Manual control and clears its DPI logic mask (allowing
disconnect of the terminal), then Manual control will be released. By
extension if the drive is configured such that the HIM can be unplugged (via
logic mask setting), then the drive will not allow the terminal to acquire
Manual control. The disconnect also applies to a DPI HIM that executes a
soft “Logout.”
9. If a com loss fault occurs on a DPI that has Manual control, then Manual
control will be released as a consequence of the fault (on that port which had
Manual control).
10. There will be no way to request and hence no support of the Auto/Manual
feature on old SCANport based HIMs.
11. You can not acquire Manual control if you are already an assigned source for
the DPI port requesting Manual.
12. When a restore factory defaults is performed Manual control is aborted.
Auto Restart (Reset/Run)
The Auto Restart feature provides the ability for the drive to automatically
perform a fault reset followed by a start attempt without user or application
intervention. This allows remote or “unattended” operation. Only certain faults
are allowed to be reset. Certain faults (Type 2) that indicate possible drive
component malfunction are not resettable.
Caution should be used when enabling this feature, since the drive will attempt to
issue its own start command based on user selected programming.
Configuration
This feature is configured through two user parameters
Setting [Auto Rstrt Tries] to a value greater than zero will enable the Auto Restart
feature. Setting the number of tries equal to zero will disable the feature.
The [Auto Rstrt Delay] parameter sets the time, in seconds, between each reset/
run attempt.
174 [Auto Rstrt Tries]
Sets the maximum number of times the drive attempts
to reset a fault and restart.
Default:

175 [Auto Rstrt Delay]
Sets the time between restart attempts when [Auto
Rstrt Tries] is set to a value other than zero.
