B-8 Parameter Information
Jam Jam A Lvl 69 %FLC 0…1000 0
Allows the user to set an instantaneous over
current level (% of line FLC) that will cause an
Alarm. A zero value is the “off” setting.
Jam Jam A Dly 70 Secs 0…99 0
Allows the user the ability to prevent some
nuisance Alarms by entering a delay period
that provides a window that the motor over
current condition must persist within for the
controller to Alarm.
Stall Stall Delay 71 Secs 0.0…10.0 0
This feature allows the user to program the
amount of time beyond the initial start
maneuver for the motor to be at speed. A
setting of zero means that the stall detection
feature is disabled.
