● When you set Pr.06-06 or Pr.06-09 to 2 or 4, an ot1 / ot2 warning displays and the drive stops running after

over-torque detection. The drive does not run until you manually reset it.

● Prevents self-cooled motor from overheating under low speed. Use an electronic thermal relay to limit the

drive’s output power.

● Setting the parameter to 0 is suitable for an inverter motor (motor fan using an independent power supply). For

this kind of motor, there is no significant correlation between cooling capacity and motor speed. Therefore, the
