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).
