12.24.7 Performing resetting automatically
• I want to reset an error with an operation for which
an operation instruction is turned off.
• I want to perform starting up by releasing a trip
automatically when a releasable error occurs.
• When the "[bb-10] automatic reset selection" is set
to 01, resetting is performed after the "[bb-12]
automatic resetting stand-by time" has elapsed
from when an operation instruction has been turned
off.
• When the "[bb-10] automatic reset selection" is set
to 02, resetting is performed after the "[bb-12]
automatic resetting stand-by time" has elapsed
from when an error has occurred.
Example operation of automatic resetting
Example 1) When [bb-10]=01
*) When [bb-11]=00, the error output becomes the
"[AL] output."
Parameters
• When the "[bb-10] automatic reset selection" is set
to 01, resetting starts when the STOP/RESET key
is pressed as long as an instruction is given through
the operation panel.
• When resetting is performed manually, and a
control power supply is turned on again, the number
of automatic resetting counted in internal is cleared.
•
By setting the "Alarm output selection [bb-11]" to 01 while
automatic resetting is valid, you can invalidate the output
of the "Alarm [AL]" during automatic resetting operation.
• Upon automatic resetting has been performed for
the number of times set with the "[bb-13] automatic
resetting count setting," no error will be released,
but a trip occurs.
Example 2) When [bb-10]=02
