2-24 Auto Restart (Reset/Run)
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.
The auto-reset/run feature provides 2 status bits in [Drive Status 2] – an
active status, and a countdown status.
The typical steps performed in an Auto-Reset/Run cycle are as follows:
1. The drive is running and an auto-resettable fault occurs, tripping the
drive.
2. After the number of seconds in [Auto Rstrt Delay], the drive will
automatically perform an internal Fault Reset, resetting the faulted
condition.
