DB Resistance

Was bedeutet 69 ?

The measured resistance of the internal Dynamic Braking (DB) resistor is outside its specified operating range. This could indicate a damaged or incorrect braking resistor, preventing effective energy dissipation during deceleration. A faulty DB resistor can lead to overvoltage trips or poor braking performance.

• Braking resistor fault or excessive temperature detected.
• Braking resistor value out of specified range.
• Braking resistor connected improperly or shorted.
• Excessive regenerative energy requiring braking resistor activation.
