Controlling Moves In Progress
Each SV160E2 has the ability to place a running move on hold and later resume the move if an error did not
occur while the move was in its Hold state. One potential application for this feature is bringing a move to a
controlled stop when your controller senses an end-of-stock condition. The move can be put in its Hold state
until the stock is replenished and then the move can be resumed.
Note that you do not have to resume a move once it has been placed in its Hold state. You can place a move in
its Hold state to prematurely end the move with a controlled stop and issue a new move of any type from the
stopped position.
The figure below shows a profile of a move that is placed in its Hold state and later resumed.

Jog Moves
Jog Moves can be brought to a controlled stop by issuing a Hold Move command, but they cannot be
restarted.
Registration Moves
Registration Moves can be brought to a controlled stop by issuing a Hold Move command, but they cannot be
restarted.
Absolute and Relative Moves
Absolute and Relative Moves can be placed in a Hold state and resumed if error conditions, such as program-
ming errors, have not occurred. New Acceleration, Deceleration, and Programmed Speed parameters can be
written to the SV160E2 while these moves are in their hold states. If the parameters are accepted without
error, the move can be resumed and it will use the new parameter values. Note that a change to the Target
Position is ignored.
Disabling the Motor
It is possible to disable the motor while a move is in progress. If this occurs, the SV160E2 uses the move’s
programmed deceleration rate to bring motion to a stop before removing power from the motor. The
SV160E2 also issues a command error when the motor is disabled during a move.
