SDC2130 - Overheat fault

5 years 3 months ago - 5 years 3 months ago #29530710 by DCON
Hello,
I'm using an SDC2130 with a reducted motor, and sometimes the controller does not power anymore the motor.
I've wired it to the PC, and an Overheat fault is detected. The script is still running.
This fault seems weird because it occurs even if the external temperature is about 20°C and the controller wasnt in duty before.

When I power OFF and power ON the controller, it works correctly. I can ask higher duty to the controller and no more fault happens anymore.

Can someone explain me this fault, and if there is something to do to reset it ?

Sounds like it may have been damaged from voltage spike. What is the source of power to the controller; Power supply or battery?

At any point of time, did you ever remove the power when the motor was running; damage from motor regen?

The power source is a battery and can be shutdown at anytime. Most of the time this is done when the motor is not in duty.
Is the damage irreversible ?

If the overheat comes on, it sounds like the problem is in the output stage. The damage in itself if it is faulty, was possibly caused by motor regen. The overheat if not a true fault, can come on if something in your setting is not correct and the motor tries to do something. Sometimes a closed loop mode setting can cause this.

Are you running in open loop or closed loop mode? Have you tried doing a reset to defaults, power cycling the controller afterwards, and then seeing if the fault clears?

I'll try this.
