6. Phase loss alarm
The driver has a motor phase loss alarm function, which can detect the phase loss state of the motor
during stationary and movement. During the operation of the stepper motor, due to mechanical reasons,
the winding wire of the motor may be loosened and disconnected. At this time, the driver will output an
alarm signal to prevent the device from making an erroneous action.
Since this function relies on the current detection of the motor windings, this function has a false alarm
when the motor current is too small (less than 300 mA). At this point, the user can turn off this function. In
the parameter management and setting interface of the debugging software, set parameter No.
188(phase loss detection enable) to 0.
7. Internal motion control function
When operating in the internal pulse command mode, the PUL and DIR ports are used as IO input
signals. The function of the IO needs to be set by the debugging software. As shown below:
