Q7 ASD Installation and Operation Manual
Low Current Setting
Program
⇒
Protection
⇒
Low Current Set
The Low-current Trip parameter enables this function. The Low Current
Setting establishes the low-current trip threshold. 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 Time
Program
⇒
Protection
⇒
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
Low Current Trip
Program
⇒
Protection
⇒
Low Current Trip
This parameter Enables/Disables the low-current trip feature.
When enabled, the ASD will trip on a low-current fault if the output current of
the ASD falls below the level defined at the Low Current Setting parameter
for a duration that exceeds the Low Current Time parameter setting.
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Lower Deviation Limit
Program
⇒
Feedback Settings
⇒
Lower Dev 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 #1
⇒
Lower Limit Freq
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
