 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. 
   
0–250% (100% corresponds to the rated current of the drive) 
 Set the maximum output current of the drive. Use Pr.11-17–11-20 to set the drive’s output 
current limit. 
Electronic Thermal Relay Selection 1 (Motor 1) 
Electronic Thermal Relay Selection 2 (Motor 2) 
0: Inverter motor (with external forced cooling) 
1: Standard motor (motor with fan on the shaft) 
 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 action of electronic thermal relays remains stable in low speed 
to ensure the load capability of the motor in low speed.
