Brake resistor overtemperature

Hva betyr 42 ?

The brake resistor has exceeded its safe operating temperature limit. This indicates that the resistor is dissipating too much energy, possibly due to excessive braking, incorrect resistance value, or insufficient cooling.

• Brake resistor is undersized for the application's braking energy.
• Excessive regenerative energy being fed back into the drive.
• Faulty brake resistor element.
• Brake control parameters set incorrectly (e.g., P5-01, P5-02).

1. 1

   Measure the resistance of the brake resistor using a multimeter.

2. 2

   Verify the brake resistor is properly connected to terminals BR1 and BR2.

3. 3

   Check the duty cycle of braking energy and compare with resistor specifications.

4. 4

   Monitor the voltage across the brake resistor terminals during deceleration.
