Low Current Trip Threshold
Program Protection Settings Low Current Trip Threshold
The Low-current Trip parameter enables this function. The Low Current
Trip Threshold establishes the low-current threshold value. The threshold
value is entered as a percentage of the maximum rating of the ASD.
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 100.00
Units — A
Low Current Trip Threshold Time
Program Protection Settings Low Current Time
When the low-current monitor is enabled, this function sets the time that the
low-current condition must exist to cause a trip.
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Units — Seconds
Lower Deviation Limit
Program Feedback Settings Lower Deviation Limit
This parameter determines the maximum amount that the feedback may
decrease the output signal.
Parameter Type — Numerical
Factory Default — 50.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 50.00
Units — %
Lower Limit Frequency
Program Fundamental Parameters Fundamental #1 Lower
Limit Frequency
This parameter sets the lowest frequency that the ASD will accept as a
frequency command or frequency setpoint. The ASD will output frequencies
lower than the Lower Limit Frequency when accelerating to the lower limit or
decelerating to a stop. Frequencies below the Lower Limit may also be output
when operating in the PID Control mode, Torque Control mode, or the
Vector Control modes (sensorless or feedback).
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Upper Limit
Units — Hz
Low Output Disable Boost Level
Program PID Setup Low-output Disable Boost Level
The Low Output Disable feature adds the user-input frequency value to the
commanded frequency (Hz).
Parameter Type — Numerical
