Characteristics
Protection
- Overload-49
- Motor current is detected and is applied to I2t. If it reaches the characteristic curve, overload protection is on.
- The overload function can be set to be on when the current is increased by 600% in consideration of motor operating time. Since operation time can be set from 1 second to 60 seconds in 1-second increments, up to 60 classes can be decided for overload characteristic curves.
- In the definite time mode, regardless of motor heat, current after delaytime is
