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.
