ABB ACS880-x04, Firmware Manual

274 Parameters
31.13 User selectable
fault Defines the fault that can be automatically reset using
parameter
31.12 Autoreset selection , bit 10.
The faults are listed in chapter Fault tracing (page 519 ).
0000h
0000h…FFFFh Fault code. 10 = 1
31.14 Number of trials Defines the maximum number of automatic resets that the
drive is allowed to attempt within the time specified by
31.15
Total trials time .
If the fault persists, subsequent reset attempts will be made at
intervals defined by
31.16 Delay time .
The faults to be automatically reset are defined by 31.12
Autoreset selection .
0
0…5 Number of automatic resets. 1 = 1
31.15 Total trials time Defines a time window for automatic fault resets. The
maximum number of attempts made during any period of this
length is defined by
31.14 Number of trials .
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.
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 (or a
previous reset attempt) 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.
Note: The drive may not be able to reliably detect a phase
loss in a multimotor application: a separate protection method
(eg. a motor protection switch) should be installed for each
motor.
Fault
No action No action taken. 0
Fault The drive trips on fault 3381 Output phase loss . 1
31.20 Earth fault Selects how the drive reacts when an earth fault or current
unbalance is detected in the motor or the motor cable.
See also section
Earth (Ground) fault detection (parameter
31.20) (page 86 ).
Fault
No action No action taken. 0
Warning The drive generates an A2B3 Earth leakage warning. 1
Fault The drive trips on fault 2330 Earth leakage . 2
