Error
A high indication on this register indicates that one of the analog parameters specified
above is invalid or the stepper action was aborted before the operation was complete.
This register is cleared on the next start command if the error was corrected.
The stepper requires one discrete register to control the stepper action. Setting this register
starts the stepper cycle. This register must remain set to complete the entire cycle. Clearing this
register before the cycle is complete aborts the step sequence and sets the error bit.
Note that setting the PLC mode to Stop while the stepper is in operation causes the
stepper output to immediately drop to zero and the current stepper count to be lost.
Note that stepper output level may cause damage or be incompatible with some motor
driver inputs. Consult drive documentation to determine if output level and type is
compatible.
