8.4. Short-term controller loss

The controller to go down due to the overcurrent protection (the hard stop of the motor can lead to the current surge due to recuperation). In cases of using the big motors (which require the winding current up to 3A) or the big mechanical load on the motor a current surge may exceed the safe value that triggers the protection.


Generally the recuperation problem is common for controllers with serial number 12804 and 12617

The possible solution: is to decrease the acceleration and deceleration values of stepper motor settings (XiLab -> Settings menu -> Stepper motor tab).
