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)
Overtorque Trip
Program ⇒ Protection ⇒ Overtorque Parameters
This parameter Enables/Disables the Overtorque 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 overtorque conditions.
Note: A discrete output terminal may be activated when an overtorque
alarm occurs if so configured (see F130).
Settings:
0 — Disabled
1 — Enabled
