Questions and answers
Here is showing problems low rating speed and beep beep continues after 2 minutes automatically off
The cause of low rating speed and continuous beeping after 2 minutes on the Grant FF Series could be:
- Reamer motor RPM dropped by more than 7%. Check the frequency (Hz); if it's lower than 45Hz, this may be the issue.
- Speed reducer issues, such as:
- Faulty speed reducer motor or box – replace if needed.
- Low oil in speed reducer – replace motor/box.
- Worn bearings – replace bearings.
- Motor capacitor may be faulty – check and replace if needed.
Continuous beeping may also be due to the buzzer being enabled via DIP switch 6.
