Brake wear Display error

What does 106 mean?

The brake lining wear sensor indicates that the brake lining is worn down. Worn brake linings reduce braking effectiveness, increase stopping distances, and can lead to mechanical failure or unsafe conditions if not replaced promptly.

• Normal wear and tear of brake linings due to exceeding the specified number of braking cycles (e.g., 1 million cycles) or operating hours.
• Excessive or frequent braking applications (e.g., high-cycle stopping, emergency stops) without sufficient cool-down.
• Incorrect brake adjustment (e.g., brake air gap too small), causing continuous rubbing of linings when disengaged.
• Overloading the motor/drive system, requiring higher brake torque and increasing wear rates during deceleration.
• Malfunction of the brake wear sensor itself, providing a false positive signal (e.g., sensor short-circuit or internal fault).

Click steps to track your progress.

1. 1

   1. Physically inspect the brake linings through inspection ports (if available) to confirm visible wear level against manufacturer specifications.

2. 2

   2. Measure the brake air gap with a feeler gauge; adjust to manufacturer specification (e.g., 0.2-0.5 mm between armature plate and coil body).

3. 3

   3. Verify the number of accumulated braking cycles against the manufacturer's specified service life via drive diagnostics (if available).

4. 4

   4. Check the brake control voltage (e.g., 24VDC) at the brake coil terminals to ensure proper disengagement.

5. 5

   5. Plan and schedule replacement of the brake linings or the entire brake assembly, using original spare parts (e.g., brake kit BMG150).
