What to do if SAJ Controller shows running time reached?
- TthayesSep 18, 2025
If the SAJ Controller indicates that the running time has reached the set value, restore factory settings.

What to do if SAJ Controller shows running time reached?
If the SAJ Controller indicates that the running time has reached the set value, restore factory settings.
What to do if my SAJ Controller shows a controller overload error?
If the SAJ Controller displays a 'Controller overload' error, it could stem from several causes. The acceleration might be too rapid, so try increasing the acceleration time. It is also possible that the input voltage is too low, requiring you to check the input power supply and wiring. If the motor was restarted immediately after a trip-off, avoid doing this. Lastly, the load might be too heavy, suggesting the need to replace with a higher-rating controller.
Why is my SAJ Controller overheating?
If your SAJ Controller is overheating, it could be due to several reasons. There might be an instantaneous over-current, so refer to the over-current remedy. Another potential cause is an output short circuit, requiring re-wiring of the output. The ambient temperature could also be too high; if possible, decrease it. Check for loose cables or terminals and tighten them. If the power circuit is abnormal, ask for support.
What causes a communication fault in SAJ Controller?
If you are experiencing a communication fault with your SAJ Controller, there are a few things you can check. First, ensure that the baud rate is set correctly. Second, verify that the upper machine is working normally. Finally, inspect the communication devices and cables for any long-time communication interruptions.
What to do if SAJ Controller shows powering time reached?
If the SAJ Controller indicates that the powering time has reached the set value, restore factory settings.
What causes EEPROM checking failure on SAJ Controller?
If the SAJ Controller shows EEPROM checking failure, it is because the EEPROM is damaged, so ask for technical support.
What causes an output phase loss on a SAJ Controller?
If the SAJ Controller shows an output phase loss, it could be due to broken wires in the output cable, so check the wiring and installation.
What causes overload of buffer resistor in SAJ Controller?
If the SAJ Controller experiences overload of the buffer resistor, it is due to abnormal input voltage, so adjust input voltage to normal range.
What causes over-voltage during acceleration in SAJ Controller?
If the SAJ Controller shows an over-voltage during acceleration, it may be due to abnormal input voltage, so check input power. Another cause could be restarting the motor when instantaneous trip-off occurs; avoid prompt restart when trip-off.
Why am I getting over-current at constant running speed on my SAJ Controller?
If the SAJ Controller experiences an over-current at constant running speed, a sudden change of load may have occurred, so check the load. Also, the input voltage might be too low, so check the input power supply or wiring.
