The following figure shows an example of an output sequence for the forward direction when
DIn.0 is being used as a limit switch.
Figure 4-11 Example of an output sequence (limit switch)
Aborting the output sequence
If you reset the SW_ENABLE control bit, the software enable is deactivated and the current
output sequence is aborted. If canceled, the last period will not be completed. The feedback
bit STS_ENABLE and DQn.A and DQn.B are reset (engine stop).
If you use the HW enable, you can alternatively cancel the output sequence with a falling
edge at DIn.0. If you use the limit switch instead of the HW enable, you can alternatively
cancel the output sequence with a rising edge at DIn.0.
A renewed pulse output is only possible after a restart of the output sequence.
