E-Stop reset
Important: The slave servo of the deskewed pair moves independently
to compensate for any skew that may exist between the master and slave
servo when E-Stop is reset. This eliminates any skew that may have
occurred from servo drift during E-Stop or any skew that may have
existed before entering E-Stop. This move occurs at the Medium/Low
jog speed.
ATTENTION: The Deskew feature is used to control the skew
when two servos drive one axis. Skew occurs when one servo’s
position is not the same as the other servo in the pair. If too
great a skew occurs, damage may result to the axis and its drive
components due to mechanical binding of the drive system.

Damage could occur if the servos are not
closely synchronized.
