132 Q9 ASD Installation and Operation Manual
Low-Current Detection Hysteresis Width
Program Protection
During a momentary low-current condition, this parameter provides a current
threshold level to which the low-current condition must return within the time
setting of F612 or a Low-Current Trip will be incurred.
Direct Access Number — F609
Parameter Type — Numerical
Factory Default — 10
Changeable During Run — Yes
Minimum — 1
Maximum — 20
Units — %
Low-Current Trip
Program Protection
This parameter Enables/Disables the low-current trip feature.
When enabled, the drive will trip on a low-current fault if the output current of the
drive falls below the level defined at F611 and remains there for the time set at
F612.
Settings:
0 — Disabled
1 — Enabled
Direct Access Number — F610
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Low-Current Detection Threshold
Program Protection
With the Low-Current Trip (F610) parameter enabled, this function sets the low-
current trip threshold.
The threshold value is entered as a percentage of the maximum rating of the drive.
Direct Access Number — F611
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 100
Units — %
Low-Current Trip Threshold Time
Program Protection
With the Low-Current Trip (F610) parameter enabled, this function sets the time
that the low-current condition must exist to cause a trip.
Direct Access Number — F612
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Units — Seconds
Short Circuit Detection At Start
Program Protection
This parameter determines when the system will perform an Output Short
Circuit test.
Note: Selection 3 is recommended for high-speed motor applications.
Because of the low impedance of high-speed motors the standard-
pulse setting may result in a motor malfunction.
Settings:
0 — Every Start (Standard Pulse)
1 — Power On or Reset (Standard Pulse)
2 — Every Start (25 µS Pulse)
3 — Power On or Reset (25 µS Pulse)
4 — Every Start (10 µS pulse)
5 — Power On or Reset (10 µS Pulse)
Direct Access Number — F613
Parameter Type — Selection List
Factory Default — Every Start (standard
pulse)
Changeable During Run — No
