Brake

What does 58 mean?

The actual status feedback from the mechanical brake (e.g., open/closed) does not match the drive's control signal for the brake. This indicates a malfunction in the brake mechanism, its feedback sensor, or the associated wiring. A malfunctioning brake poses a safety risk and can prevent proper machine operation or holding.

• Mechanical brake wear or damage preventing full engagement or disengagement.
• Brake feedback switch (e.g., limit switch) faulty, stuck, or misaligned.
• Drive output voltage to brake coil (e.g., 24VDC) lost or below required level.
• Brake coil internal short circuit or open circuit preventing proper current flow.
• Parameter P3-12 (Brake control type) incorrectly configured for the brake hardware.

Click steps to track your progress.

1. 1

   Verify drive output voltage to brake coil terminals (e.g., X1:1, X1:2) matches specified voltage (e.g., 24VDC) when commanded open/closed.

2. 2

   Measure resistance of brake coil windings; compare to manufacturer's specifications (e.g., 20 Ohms).

3. 3

   Actuate brake manually (if possible) and visually confirm mechanical movement and feedback switch activation.

4. 4

   Test continuity of brake feedback switch contacts (e.g., on terminals X2:3, X2:4) in both open and closed states using a multimeter.

5. 5

   Check drive parameter P3-12 for correct brake control configuration (e.g., '0 = No brake', '1 = Dynamic brake').

6. 6

   Inspect brake mechanism for physical obstructions, wear, or damage to pads or spring assembly.
