When the run signal is removed from the master drive the slave drive will follow the master to a stop.
When the alignment process has completed the “Align Slave” input may be removed to prevent continuous
alignment. The “Aligned Output” will not reset until the “Align Slave” input has been removed and reactivated.
1.4 Alignment Check Description
When operating in lineshaft mode an alignment check is performed. This check monitors the difference in
quadrature counts that separates the trigger inputs. The alignment offset is factored into the calculation. If the
error count exceeds the value set in P1-10 the alignment check output will be off. This output will only change
states after an alignment check. When the alignment check output is on it indicates that the error count between
the master and slave trigger inputs was less than the value set in P1-10 when last checked.
