This constant determines whether the overtorque detection function of the GPD
205 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 “ 3 ” or “ 4 ”.
— For continuous operation after overtorque detection, set to “ 1 ” or
“ 3 ”. During detection, the Digital Operator displays and “ o o L L 3 3 ”
alarm (blinking).
— To stop the drive at an overtorque detection fault, set to “ 2 ” or
“ 4 ”. At detection, the Digital Operator displays an “ o
o L L 3 3 ” fault.
— To output an overtorque detection signal, set output terminal function
selection (n n 0 0 9 9 or n n 1 1 0 0 ) to “ 6 ”.
Overtorque detection compares GPD 205 actual output current with the overtorque
detection level. When the output current is equal to or greater than the detection
level, an overtorque condition exists. This will be indicated as on “ o
o L L 3 3 ” fault or
warning on the Digital Operator, or an equivalent indication on the Status Indicator
LEDs. (The detection level is a percent of GPD 205 rated output current; see
Appendix 1.)

This is the reference point for determining that an overtorque condition exists. Set
as a percent of GPD 205 rated current (see Appendix 1).

Determines how long an overtorque condition must exist before another event will
occur, i.e. coast stop, multi-function output change of state, or o
o L L 3 3 warning or fault
display.
