202 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:
0000h
0000h…FFFFh 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 345).
Note: The fault codes are in hexadecimal. The selected
code must be converted to decimal for this parameter.
0
0000h…FFFFh Fault code. 10 = 1
31.14 Number of trials Defines the number of automatic fault resets the drive
performs within the time defined by parameter 31.15 Total
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
31.19 Motor phase loss Selects how the drive reacts when a motor phase loss is
detected.
