Low Current Trip Threshold
Program ⇒ Protection Parameters ⇒ Low Current Settings
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.
Direct Access Number — F611
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Ye s
Minimum — 0.00
Maximum — 100.0
Units — %
Low Current Trip Threshold Time
Program ⇒ Protection Parameters ⇒ Low Current Settings
When the low-current monitor is 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 — Ye s
Minimum — 0
Maximum — 255
Units — Seconds
Short Circuit Test
Program ⇒ Protection Parameters ⇒ Arm Short Check Settings
This parameter determines when the system will perform an Output Short
Circuit test.
Settings:
Every Run
Every Powerup
Direct Access Number — F613
Parameter Type — Selection List
Factory Default — Every Run
Changeable During Run — No
Short Circuit Test Duration
Program ⇒ Protection Parameters ⇒ Arm Short Check Settings
This parameter sets the pulse width of the output pulse that is applied to the
ASD output during an Output Short Circuit test.
Direct Access Number — F614
Parameter Type — Numerical
Factory Default — (drive dependent)
Changeable During Run — No
Minimum — 1
Maximum — 100
Units — µS
Overtorque Trip
Program ⇒ Protection Parameters ⇒ Overtorque Parameters
This parameter Enables/Disables the Over Torque Tripping function.
When enabled, the ASD trips if a torque larger 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.
Direct Access Number — F615
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
