Car Stuck Detection (OL3, Using Overtorque detection)
The Overtorque detection function can be used to detect a stucked car. The torque detection function 1 can be
used for this. Therefore a digital output has to be programmed for “Overtorque detection 1” (H2-
= B or
17). Using this with the factory setting car stuck is detected (output is switched) torque/current is higher than
150% for 10 sec. The level can be adjusted in L6-02, the time in L6-03. The output is switched of and an OL3
fault will be indicated (see .
