When an excessive load is placed on the machine, the increase in
motor current is detected and alarm signal can be output.
If the current exceeds the value set in No. 38 for longer than the
time limit set in No. 39, the overtorque detection signal is output to
control circuit terminal 13 or 14 until the current falls below the
value set in No. 38.
To output the signal to control circuit terminal 13, set constant No.
34 to 4. To output the signal to control circuit terminal 14, set con-
stant No. 35 to 4.

The second digit of No. 37 determines whether overtorque will be
detected during acceleration and deceleration, and the third digit
determines whether overtorque will be treated as a fault (OL3) or
operation will continue after overtorque is detected.
