3.6.3 Effect of the Directional Enables
Description
You enable the digital outputs directionally using the DIR_M and DIR_P control bits.
● With DIR_M = 1 you can move in the minus direction.
● With DIR_P = 1 you can move in the plus direction.
Interrupting and Continuing the Run
If you reset the relevant directional enable during a run, the motion of the axis is halted, all 3
digital outputs are set to 0, and the run is interrupted.
If you set the relevant directional enable again, the run is continued.
3.6.4 Stop (MODE 0)
Definition
If you activate MODE 0, the 1PosInc/Digital stops the current run, all 3 digital outputs are set
to 0, and the run is terminated (POS_ERR = 0, POS_DONE = 1).
A run terminated with MODE 0 cannot be continued. To put the axis into motion again, you
start a new MODE.
