External interlock activated

What does 60 mean?

An external interlock, configured to stop the drive, has been activated via a digital input. This prevents the drive from operating until the interlock condition is cleared and a reset signal is sent, ensuring safety or process integrity.

• An external safety circuit (e.g., E-stop, guard switch) connected to a digital input has been activated.
• A process fault signal (e.g., high temperature, low pressure, level switch) has triggered an interlock via a digital input.
• Wiring fault to the digital input (e.g., loose wire, short to common) causing a false interlock signal.
• Incorrect configuration of a digital input function (e.g., P5-10 to P5-15) leading to unintended interlock activation.
• Faulty external sensor or switch providing a continuous interlock signal.

Click steps to track your progress.

1. 1

   1. Identify the specific digital input (e.g., DI1, DI2) configured as an interlock using parameters P5-10 to P5-15.

2. 2

   2. Monitor the status of the identified digital input in the drive's monitoring menu (e.g., P16-20) to confirm its active state.

3. 3

   3. Trace the wiring from the digital input terminal back to the interlock device (e.g., limit switch, safety relay).

4. 4

   4. Verify the physical state of the interlock device (e.g., check if a guard is open, if an E-stop button is pressed).

5. 5

   5. Confirm the digital input parameter (e.g., P5-10) is correctly set for the desired logic (e.g., Normally Open/Normally Closed).

6. 6

   6. Test the external interlock device and its wiring for continuity with a multimeter to ensure proper operation.
