Torque Detection - Veikong gpd 515/g5 Startup Manual

5 . 4 4 T O R Q U E DETECTION
Torque detection is used to compare drive rated output current with the overtorque
detection level. When the output current is equal to or greater than the defined level, an
overtorque condition exists. This will be indicated as an " OL3 " fault on the Digital
Operator. This feature can be selected to operate over a wide range of conditions.
A . L 6 - 0 1 : Torque Detection Selection 1
L 6 - 0 4 : Torque Detection Selection 2
These parameters determine whether the torque detection function of the drive is
enabled, under what conditions it will detect for overtorque, and what operation it will
perform after detecting an overtorque.

— For overtorque detection during accel or decel, set to " 2 " or " 4 ".
— For continuous operation after overtorque detection, set to " 1 " or
" 2 ". During detection, the Digital Operator displays and " O L 3 "
a l a r m ( b l i n k i n g ) .
— To stop the drive at an overtorque detection fault, set to " 3 " or
" 4 ". At detection, the Digital Operator displays an " O L 3 " fault.
B . L 6 - 0 2 : Overtorque Detection Level 1
L 6 - 0 5 : Overtorque Detection Level 2
These are the reference points for determining that an overtorque condition exists. Set as
a percent of drive rated current (see Appendix 2).
C . L 6 - 0 3 : Overtorque Detection Time 1
L 6 - 0 6 : Overtorque Detection Time 2
Determines how long an overtorque condition must exist before another event will occur,
e.g. coast to stop, multi-function output change of state, or "
display.
