Collective brake fault, KPP/KSP (axis)

Hva betyr 26133 ?

This fault indicates an issue detected by the brake cable monitoring device, signaling a short-circuit, overloading, or a break in the brake connection, or that no brake is connected. This compromises the safety function of the motor brake, potentially leading to uncontrolled axis movement or dropped loads.

• Short-circuit in the brake circuit or brake cable.
• Overloading of the brake circuit.
• Break in the brake cable connection.
• No brake connected to the axis.
• Fault in the KSP module's brake control.

1. 1

   Check brake voltage at the brake terminals (note if fault occurs in all axes).

2. 2

   Measure the motor brake resistance for opens or shorts.

3. 3

   Check brake cable and motor cable for damage, continuity, and proper connections.

4. 4

   Reinitialize the drive bus: Power Off / Power On.

5. 5

   Check KSP module for faults related to brake control.
