Overcurrent

Was bedeutet 1 ?

The frequency converter has detected a motor current exceeding four times the nominal current (>4*IN) in the motor cable. This condition typically results from a sudden heavy increase in motor load, a short circuit in the motor cables, or the use of an unsuitable motor for the application, posing a risk of damage to the motor or drive.

• Motor draws excessive current.
• Short circuit in motor windings or cables.
• Mechanical overload or jamming.
• Rapid acceleration or deceleration ramps (P1-16, P1-17).
• Output voltage too low relative to motor speed.

1. 1

   Check the motor loading to ensure it is within the rated capacity of the drive and motor.

2. 2

   Verify the motor size matches the application requirements and the frequency converter specifications.

3. 3

   Inspect all motor cables for any signs of physical damage, insulation breakdown, or short circuits between phases or to ground.
