Block Title	Parameter	Description
Advanced	Current	Rated Current – (View Only) this value is the continuous current rating of the control.
		Low Current – If on, activates low current trip protection. Useful to detect a low current
		condition (broken belt, coupling, pump etc.) on driven equipment.
		Low Current Level – The value of the low current trip detection. Value can be 0 to 100%
		of the Rated Current parameter value. Parameter 28.
		Low Current Time – The number of power cycles the motor current is allowed to remain
		below the low current level before a low current trip occurs. Value can be 5 to 255
		cycles. Parameter 29.
		C/L Time Out – If on, allows current limit time out trip (active).
		Current Limit – The value of the current limit trip detection. Value can be 1 to 7.9 times
		the Rated Current parameter value. Parameter 30.
		Limit Time Out – The number of seconds
		Value can be 0 to 255 seconds. Parameter 31.
		Shearpin – If on, Shearpin protection is active. Useful to detect a high current condition
		(such as a jammed conveyor or press) on driven equipment.
		Shearpin Level – The value of the high current Shearpin trip detection. Value can be 1 to
		5 times the Rated Current parameter value. Parameter 32.
		Shearpin Time – The number of power cycles the motor current is allowed to remain
		above the low shearpin level before a Shearpin trip occurs. Value can be
		cycles. Parameter 33.
		Overload Level – Provides overload protection for SCR’s. (Not for motor thermal
		overload). The value of the overload current trip detection. Value can be 0.6 to 2
		times the Rated Current parameter value. Parameter 34.
		Overload Delay – A numerical value that represents the time and current characteristics
		for overload integration. Value can be 10 to 140. Parameter 35.
		Note: For applications that have frequent Start/Stop sequences, it is necessary to
			maintain 115VAC at terminals X1 and X2. Removing 115VAC from these
			terminals resets the overload delay integration to 140.

	Optimise Rate	A numerical value that represents the rate at which the motor voltage is reduced during
		optimizing. When this number is large, improves efficiency on stable loads. A lower
		number for unstable loads will reduce speed variations. Value can be 4 to 30.
		Parameter 19.
	Kick Start	If on, Kick Start feature is active.
	Kick Pedestal	For traction or “frozen” loads, this boost pulse of higher voltage helps the load to start
		moving. Value can be 60% to 90% of line voltage. Parameter 13.
	Kick Time	Number of cycles duration the kick pedestal voltage is applied. Value can be 10 to 40.
		Parameter 14.
	Dwell Time	Number of seconds that full voltage is applied to the motor before optimizing begins (if
		optimizing is selected). Value can be 1 to 255. Parameter 15.
	Low Volts Stop	Allows decel to zero volts (not just to the level of the start pedestal). (Sometimes helpful
		for unstable loads or regeneration).
