Tips: what circumstance is offline signal of hybrid stepper driver generally used?
When the offline signal FREE is low level, the current output to the motor by the driver is cut off and the motor rotor is at free state (offline state). as for some automatic device, under the circumstance that the power of drive is not disconnected, it is required to directly rotate the motor shaft (manual mode) to put the signal FREE on the bottom, so that the motor is at offline state. As for manual operation or adjustment, after manual completion, the signal FREE can be put in higher position to realize continuous automatic control.
