Low-Current Detection 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.
Direct Access Number — F612
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
Units — Seconds
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
2 — Never
Direct Access Number — F613
Parameter Type — Selection List
Factory Default — Check at Every Run
Changeable During Run — No
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.
Direct Access Number — F614
Parameter Type — Numerical
Factory Default — 50
Changeable During Run — No
Minimum — 1
Maximum — 100
Units — µS
Over-Torque Trip Selection
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
Direct Access Number — F615
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — Yes
Over-Torque Detection Level During Power Running
Program

Protection

Over-Torque Parameters
This parameter sets the torque threshold level that is used as a setpoint for over-
torque tripping during positive torque. This setting is a percentage of the
maximum rated torque of the ASD.
This function is enabled at F615 .
Direct Access Number — F616
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0.00
Maximum — 250.00
