Motor Timed Overload Trip (Adv. Code 0)

¿Qué significa 20 ?

This fault signifies that the motor connected to the drive has experienced an overload condition exceeding the customer-defined overload settings. Sustained operation above the motor's rated current can lead to winding damage, reduced motor lifespan, or premature motor failure. The drive tripped to protect the motor.

• Motor drawing current consistently above its nameplate rated current (P1-03) due to excessive mechanical load on the driven equipment.
• Motor overload settings (e.g., P1-07 Motor Overload Factor, P1-08 Motor Current Limit) are set too low for the actual application demands.
• Improperly sized motor for the application, leading to continuous operation beyond its thermal capacity.
• Inaccurate motor parameters (P1-01 through P1-07) entered into the drive, causing incorrect overload protection calculations.
• Motor cooling fan failure or blocked air passages on the motor itself, leading to internal overheating.

1. 1

   1. Monitor output current (P0-01) during normal operation and compare it to the motor's nameplate rated current (P1-03).

2. 2

   2. Mechanically inspect the driven load for binding, excessive friction, or changes in process conditions that increase required torque.

3. 3

   3. Increase the Motor Overload Factor (P1-07) or Motor Current Limit (P1-08) within the safe operating limits of the motor and drive.

4. 4

   4. Verify all motor parameters (P1-01 Motor Type, P1-02 Motor Power, P1-03 Motor Rated Current, etc.) are correctly entered into the drive.

5. 5

   5. Perform a temperature check on the motor casing using a thermal imaging camera or contact thermometer to confirm actual motor operating temperature.
