174 [Auto Rstrt Tries]
Sets the maximum number of times the
drive attempts to reset a fault and restart.
Default:
Min/Max:
Units:
0
0/9
1
Important: The drive will re-start after a reset if the start input is still asserted.
Specifies the maximum number of times the drive attempts to reset a fault and
restart when the auto restart feature is enabled.
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. Only
certain faults are permitted to be reset, see chapter 12 for more information.
When the auto restart feature is enabled (that is, Auto Rstrt Tries is set to a value
greater than zero), and an auto-resettable fault occurs, the drive will stop. After the
number of seconds in [Auto Restrt Delay] has elapsed, the drive will automatically
reset the faulted condition. The drive will then issue an internal start command to
start the drive.
If another auto-resettable fault occurs, the cycle will repeat up to the number of
attempts specified in Auto Rstrt Tries.
If the drive faults repeatedly for more than the number of attempts specified in
Auto Rstrt Tries with less than five minutes between each fault, the drive will
remain in the faulted state. The fault Auto Rstrt Tries will be logged in the fault
queue.
The auto restart feature is disabled when the drive is stopping and during
autotuning. Note that a DC Hold state is considered stopping.
The following conditions will abort the reset/run process:
•
Issuing a stop command from any control source. (Note that removal of a
2-wire run-fwd or run-rev command is considered a stop command.)
•
Issuing a fault reset command from any active source.
•
Removing the enable input signal.
•
Setting Auto Restrt Tries to zero.
•
Occurrence of a fault that is not auto-resettable.
•
Removing power from the drive.
•
Exhausting an auto-reset/run cycle.
Note that two autotuning status bits are provided in [Drive Status 2]: an active
status bit and a countdown status bit.

ATTENTION: Equipment damage and/or personal injury may
result if this parameter is used in an inappropriate application. Do
not use this function without considering applicable local, national
and international codes, standards, regulations or industry
guidelines.
ATTENTION: The drive may start immediately after a fault is
auto-reset when 168 [LevelSense Start] is enabled.
When LevelSense Start is enabled, the user must ensure that
automatic start up of the driven equipment will not cause injury to
operating personnel or damage to the driven equipment. In
addition, the user is responsible for providing suitable audible or
visual alarms or other devices to indicate that this function is
enabled and the drive may start at any moment. Failure to observe
this precaution could result in severe bodily injury or loss of life.
