432 Parameters
79.19 Underload event
reaction
Defines response to the underload condition.
If the underload supervision signal stays under active
underload limit as long as set in defined delay time, then the
underload protection function triggers the reaction defined in
this parameter setting.
Warning
Not selected Underload event reaction is inactive. 0
Warning Underload condition triggers the drive event D205 Underload
warning. It will stay on as long as underload condition is
present. Warning will automatically disappear if underload
supervision signal stays above the underload limit for the time
defined in parameter 79.18 Underload delay time.
1
Warning with
shutdown
Underload condition triggers the drive event D205 Underload
warning and immediate stop command. Drive will stop
according to parameter 21.03 Stop mode setting.
2
Fault Underload condition triggers the drive event D102 Underload
fault which immediately trips the drive.
3
URT Recovery -
Warning
Underload condition triggers the underload ride through
recovery sequence. In case recovery routine helps, motor
speed returns to production speed. If not, drive generates the
event D205 Underload warning. It will stay on as long as
underload condition is present. Warning will automatically
disappear if underload supervision signal stays above the
underload limit for the time defined in parameter 79.18
Underload delay time.
4
URT Recovery -
Fault
Underload condition triggers the underload ride through
recovery sequence. In case recovery routine helps, motor
speed returns to production speed. If not, drive generates the
D102 Underload fault which immediately trips the drive.
