Overload in motor

Was bedeutet 84 ?

The motor has been operating under an overload condition, causing its temperature to rise excessively or its current draw to exceed safe limits for an extended period. This can lead to motor damage if not addressed.

• Excessive mechanical load on the driven equipment
• Incorrect motor nominal current parameter setting in the drive
• Degradation of motor winding insulation leading to increased current

1. 1

   Verify mechanical load on the motor and driven equipment for any obstructions, jamming, or excessive resistance.

2. 2

   Verify motor data parameters (Nominal Current, Nominal Power, Nominal Voltage) in the SEW Eurodrive unit match the actual motor nameplate data.

3. 3

   Measure actual motor current on all three phases using a clamp meter and compare it against the motor's nominal current rating.

4. 4

   Inspect motor cooling fan for proper operation and ensure cooling fins are free from dust, dirt, or other obstructions.

5. 5

   Inspect motor cable for damage, proper sizing, and secure connections at both the SEW Eurodrive output terminals and the motor terminal box.
