Description
Defines the maximum number of automatic resets
that the drive is allowed to attempt within the time
defined by parameter
If the fault persists, subsequent reset attempts will
be made at intervals defined by
The faults to be automatically reset are defined by

Number of automatic resets.
Defines a time window for automatic fault resets. The
maximum number of attempts made during any
period of this length is defined by
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

Time for automatic resets.
Defines the time that the drive will wait after a fault
before attempting an automatic reset. See parameter

Selects how the drive reacts when an earth (ground)
fault or current unbalance is detected in the motor or
the motor cable.

Selects how the drive reacts when a supply phase loss

Note: When this option is selected, the drive will
eventually overheat or the supply bridge may be
damaged if one supply phase is lost, unless 50%
derating is done when dimensioning the system.
