Thermal overload of motor / Overcurrent in brake chopper

What does 04 mean?

This fault can signify one of two issues: either a thermal overload of the motor due to factors like high ambient temperature, inadequate heat dissipation, or excessive mechanical load; or an overcurrent condition within the brake chopper circuitry. Both conditions indicate a risk of component damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Reduce the mechanical load on the motor.

2. 4

   Increase the motor speed if the application allows.

3. 5

   Reset the fault by switching off the DC 24 V supply voltage.
