Align by Pulse (Alignment)
Closed: Alignment function is enabled and the drive will keep the number
of quadrature follower encoder counts (displacement) between the master
and follower alignment inputs equal to the displacement reference.
Note: ELS modes only.

Save Displacement
Closed: At the transition from open to closed, the current Displacement
Reference value (which can be seen in the Displacement Reference
monitor U1-94) will be saved to the Initial Alignment Displacement
Parameter (P4-01). The data will survive a power loss.
Note: ELS modes only.
Note: Since this command saves the data into non-volatile RAM, do not
continuously use this function. The drive’s storage RAM could fail causing
drive failure.

Disable Displacement Error
Closed: Displacement error will not be corrected. However, if the Align by
Pulse (Alignment) digital input (H1-XX = 89) is closed, the displacement
feedback will still be calculated and displayed (U1-95), but the follower
drive will not correct for any displacement error. This input is useful for
troubleshooting and testing.
Note: ELS modes only.
