Stall prevention

¿Qué significa E.OLT ?

The running frequency has fallen to 0 due to the activation of stall prevention, indicated by 'OL' during operation. This signifies that the motor is operating under an overload condition, causing the inverter to reduce frequency to prevent an overcurrent shutdown.

• Motor speed has dropped too low, causing overcurrent or stall condition (P1-18).
• Excessive mechanical load preventing the motor from reaching commanded speed.
• Low voltage to the motor causing reduced torque.
• Incorrect motor parameters set in the drive (e.g., P1-07, P1-08).

1. 1

   Measure the actual current drawn by the motor and compare it to its nameplate Full Load Amps (FLA) value.

2. 2

   Reduce the mechanical load on the motor.
