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
).
