Low-Current Trip Selection
Program Protection Low-Current Settings
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
at F612.
Settings:
0 — Disabled
1 — Enabled
Low-Current Detection Current
Program Protection Low-Current Settings
When the Low-Current Trip Selection (F610) is enabled, this function sets the
low-current trip threshold.
The threshold value is entered as a percentage of the maximum rating of the
drive.
Low-Current Detection Time
Program Protection Low-Current Settings
When the Low-Current Trip Selection (F610) is enabled, this function sets the
time that the low-current condition must exist to cause a trip.
Short Circuit Detection at Start
Program Protection Special Protection Parameters
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 — Check at Every Run
1 — Check at Only Power On or Reset
Short Circuit Pulse Run Duration
Program Protection Special Protection Parameters
This parameter sets the pulse width of the ASD output pulse that is applied to
the motor during an Output Short Circuit test.
