Assembled Moves (continued)
Dwell Move (continued)
1) You do not have to preset the position or home the machine before you can use a Dwell
Move. Because the Dwell Move is based on Relative Moves, it can be run from any location.
2) The Dwell Move is stored in the internal memory of the SD4840EK and can be run multiple
times once it is written to the unit. The Dwell Move data stays in memory until power is
removed, the unit is sent new Configuration Data, or a new Blend or Dwell Move is written to
the SD4840EK. As described in
Assembled Move Programming
on page 33, it is also possi-
ble to save a Dwell Move to flash memory. This move is restored on power up and can be run
as soon as you configure the SD4840EK and enter Command Mode.
Controlled Stops

The move completes without error.

You toggle the Hold Move control bit in the Network Output Data. When this occurs, the SD4840EK
decelerates the move at the deceleration rate of the present segment to the Starting Speed and ends the
move. Note that your final position will most likely not be the one you commanded. The use of the Hold
Move bit is explained in the
Controlling Moves In Progress
section starting on page 35.
Immediate Stops

The Immediate Stop bit makes a 0

1 transition in the Network Output Data.

A positive transition on an input configured as an E-Stop Input.

A CW/CWW Limit Switch is reached. If the limit that is reached is the same as the direction of travel,
for example, hitting the CW limit while running a CW move, a
Reset Errors
command must be issued
before moves are allowed in that direction again. If the limit that is reached is opposite the direction of
travel, a
Reset Errors
command does not have to be issued.
