6.6.3 Effect of the Directional Enables
Description
Using control bits DIR_M and DIR_P, you can enable control of the drive in the
corresponding direction:
● 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 by
deceleration to 0 V at the analog output, and the run is interrupted.
If you set the relevant directional enable again, the run is continued.
6.6.4 Stop (MODE 0)
Definition
If you start MODE 0, the 1PosSSI/Analog stops the current run by deceleration to 0 V at the
analog output, and the run is completed (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.
