Low-Current Detection Threshold

Program Protection Low-Current Settings
With the Low-Current Trip (F610) parameter 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 Trip Threshold Time

Program Protection Low-current Settings
With the Low-Current Trip (F610) parameter 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 — Every Start (Standard Pulse)
1 — Power On or Reset (Standard Pulse)
2 — Every Start (Short Pulse)
3 — Power On or Reset (Short Pulse)

Over-Torque Trip

Program Protection Over-Torque Parameters
This parameter Enables/Disables the Over-Torque Tripping function.
When enabled, the ASD trips if an output torque value greater than the setting
of F616 or F617 exists for a time longer than the setting of F618.
When disabled, the ASD does not trip due to over-torque conditions.
Note: A discrete output terminal may be activated when an over-torque
alarm occurs if so configured (see F130).
Settings:
0 — Disabled
1 — Enabled
