Reverse Rotation Prevention Function; Torque Ladstop Function - Omron 3G3RX User Manual

4-2 Function Mode

Reverse Rotation Prevention Function

•This function is enabled when "03" (sensorless vector control), "04" (0-Hz sensorless vector
control), or "05" (sensor vector control) is selected in control method A044/A244.
•Because of the Inverter's control characteristics, the Inverter may output a rotation signal in the
direction opposite to that of the RUN command (e.g. in a low-speed range). If the motor's reverse
rotation may cause a problem (e.g. damage to the machine driven by the motor), set reverse
rotation prevention selection b046 to "enabled".

Torque LADSTOP Function

•If "03" (sensorless vector control), "04" (0-Hz sensorless vector control), or "05" (sensor vector
control) is selected in control method A004/A244, this function temporarily stops the frequency
deceleration function (LAD) when the torque limit function is activated.
