What causes a motor overload on a SAJ Controller?
If you are experiencing a motor overload with your SAJ Controller, it could be due to incorrect settings of parameters FA.01 and FA.02; set the parameters correctly. Another possible cause is a load that is too heavy or a motor that is stuck; reduce the load or check the motor.
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.
What does external fault mean on SAJ Controller?
If your SAJ Controller is showing an external fault, it is because of an external fault signal through DI terminals. Check external faults to resolve it.
What to do if SAJ Controller shows over-voltage during deceleration?
If the SAJ Controller shows an over-voltage during deceleration, the issue might stem from a too-fast deceleration, so add proper braking units. Another cause could be abnormal input voltage; in this case, check the input power supply and wiring.
Why is there no display on my SAJ Controller keypad?
If you are getting no display on the keypad of your SAJ Controller, check whether the input voltage is in the normal range. Also, verify the connection cable between the keyboard and control board to ensure there is good contact. If these steps don't resolve the issue, the inner instrument may have failed, and you should seek technical support.
How to fix SAJ Controller interference?
If the SAJ Controller is experiencing interference, it might be due to an abnormal carrier frequency, so reduce it properly. Another cause could be an incorrect grounding method; the controller and pump should both be grounded, but not together with other external devices. Finally, if the cable between the controller and motor is too long, install an output reactor or reduce the cable length.
What causes over-current during deceleration in SAJ Controller?
If your SAJ Controller experiences an over-current during deceleration, it could be due to a couple of reasons. The deceleration might be too fast; in this case, try increasing the deceleration time. Alternatively, the load might be too heavy and have large-inertia, so add proper braking units.
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.
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 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.
