If a brake motor is getting very hot or suffering from position errors, it
may be wise to test the brake.
There are a few ways to test the brake.
In a quiet environment, it is possible to listen for the brake.
- Go to Setup, Diagnostics
- In the upper right, click the brake box and read the warning.
- Listen for a click coming from the motor.
- After exiting setup, restart the software to ensure the brake is back
to proper state.
For a noisy environment:
- Position the system to move the braked axis downwards.
- Perform the procedure to access the Lag
test.
- Prepare the system to move the braked axis downwards slowly. (negative
number in the text box for that axis, set G IPM to a low number)
- Run the lag test for that axis
- While the system is running the test, click the button "Pulse brake".
- Watch the graph.
- If the graph shows no sign of change, the brake is likely not engaging.
- If the graph spikes or a position error is received, the brake is likely
working properly.
