260 Parameters
31.12 Autoreset selection Selects faults that are automatically reset. The parameter is a
16-bit word with each bit corresponding to a fault type.
Whenever a bit is set to 1, the corresponding fault is
automatically reset.
WARNING! Before you activate the function, make
sure that no dangerous situations can occur. The
function restarts the drive automatically and continues
operation after a fault.
The bits of this binary number correspond to the following
faults:
0x0000
0x0000…0xffff Automatic reset configuration word. 1 = 1
31.13 Selectable fault Defines the fault that can be automatically reset using
parameter 31.12 Autoreset selection, bit 10.
Faults are listed in chapter Fault tracing (page 424).
0x0000
0x0000…0xffff Fault code. 10 = 1
31.14 Number of trials Defines a time window for automatic fault resets. The
maximum number of attempts made during any period of this
length is defined by 31.15 Total trials time.
Note: If the fault condition remains and cannot be reset, each
reset attempt will generate an event and start a new time
window. In practice, if the specified number of resets (31.14)
at specified intervals (31.16) take longer than the value of
31.15, the drive will continue to attempt resetting the fault until
the cause is eventually removed.
Defines the number of automatic fault resets the drive
performs within the time defined by parameter 31.15 To tal
trials time.
0
0…5 Number of automatic resets. 10 = 1
31.15 Total trials time Defines the time the automatic reset function will attempt to
reset the drive. During this time, it will perform the number of
automatic resets defined by 31.14 Number of trials.
30.0 s
1.0…600.0 s Time for automatic resets. 10 = 1 s
31.16 Delay time Defines the time that the drive will wait after a fault before
attempting an automatic reset. See parameter 31.12
Autoreset selection.
0.0 s
0.0…120.0 s Autoreset delay. 10 = 1 s
