Quick Stop Fault

What does 63 mean?

The Quick Stop function has been activated, causing the drive to stop rapidly. This fault indicates an intentional or unintentional triggering of the quick stop safety feature, designed to bring the motor to a halt quickly. Understanding its activation source is crucial to prevent unintended stops.

• An external digital input configured for Quick Stop (e.g., P3.5.1.11, P3.5.1.12 assigned 'Quick Stop') was inadvertently activated.
• A safety function (e.g., Safe Torque Off - STO, Safe Stop 1 - SS1) linked to the Quick Stop sequence has been triggered by an external safety device.
• Internal drive safety monitoring triggered the Quick Stop due to a detected critical condition (e.g., severe overcurrent, braking resistor overload).
• Parameter misconfiguration for the Quick Stop function (e.g., P3.2.4.1 Quick Stop ramp time) leading to unintended activation or misinterpretation.

Click steps to track your progress.

1. 1

   1. Identify the specific digital input or safety function (e.g., check P3.5.1.11 assigned 'Quick Stop') that initiated the Quick Stop and check its associated external device status.

2. 2

   2. Verify the state of all safety-related inputs (e.g., Safe Torque Off terminals) to ensure they are not inadvertently active or faulted.

3. 3

   3. Review the drive's fault history log for any preceding faults (e.g., overcurrent, overvoltage) that might have triggered the Quick Stop as a protective action.

4. 4

   4. Ensure the Quick Stop deceleration ramp time (e.g., P3.2.4.1) is set appropriately for the application and does not cause excessive braking torque.

5. 5

   5. Inspect the wiring of the Quick Stop digital input for shorts to active signals or ground, which could cause spurious activation.
