CHAPTER 3 OPERATION
(2) +OT/-OT / positive software OT / negative software OT
If +OT or -OT is detected during motor rotation (inactive due to normally closed contacts) or
positive software OT or negative software OT is detected, operation is stopped and immediate
controlled stop is caused according to the torque specified in parameter PA2_60 (third torque
limit).
When +OT is detected with hardware:

(1) OT detection, +OT detection and -OT detection do not turn on if OT detection at
homing is reverse. In addition, deceleration follows the setting of parameter
PA2_18 (selection of operation at OT during homing).
(2) The in-position [INP] signal shown in the figure indicates the state in the level
output mode.
(3) If the forward torque limit (parameter PA1_27) or reverse torque limit (PA1_28) is
smaller than the third torque limit (parameter PA2_60), the torque settings of the
forward torque limit and reverse torque limit are effective.
