The stepper provides two Boolean registers to provide stepper status:
Ready/Done
A high indication on this register indicates the stepper sequence can be started
(i.e. not currently busy) and also when the move is completed.
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.

Boolean Registers
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:
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:
The stepper output level may cause damage or be incompatible with some motor drive inputs.
Consult drive documentation to determine if output level and type is compatible.
