When the low-current monitor 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 Parameters
When the low-current monitor is enabled, this function sets the time that the
low-current condition must exist to cause a trip.
Short Circuit Test
Program ⇒ Protection Parameters
This parameter determines when the system will perform an Output Short
Circuit test.
Settings:
Every Run
Every Powerup
Short Circuit Test Duration
Program ⇒ Protection Parameters
This parameter sets the pulse width of the output pulse that is applied to the
