Basic Move Types (continued)
Absolute Move (continued)
Controlled Stop Conditions
The move completes without error.
You toggle the Hold_Move control bit in the Network Output Data. Note that your holding position will
most likely not be the final position you commanded. You can resume a held Absolute Move by using
the Resume_Move bit or the move can be aborted by starting another move. The use of the Hold_Move
and Resume_Move bits is explained in the
Immediate Stop Conditions
The Immediate Stop bit makes a 0
1 transition in the Network Output Data.
An inactive-to-active transition on an input configured as an E-Stop Input.
A CW or CCW 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.
CW/CCW Jog Move
Jog Moves move in the programmed direction as long as the command is active. Two commands are avail-
able. The CW Jog Move will increase the motor position count while the CCW Jog Move will decrease the
motor position count. These commands are often used to give the operator manual control over the axis.
Jog Moves are also used when you are interested in controlling the speed of the shaft instead of its position.
One such application is driving a conveyor belt. To accommodate these applications, the running speed,
acceleration, and deceleration of the Jog Move can be changed
while the move is in progress
.
The CW Limit and CCW Limit inputs behave differently for CW/CCW Jog Moves and CW/CCW Registra-
tion Moves than all other move types. Like all moves, activating a limit will bring the move to an Immediate
Stop. Unlike other moves, a Jog or Registration move can be started when an end limit switch is active pro-
vided that the commanded direction is opposite that of the activated switch. For example, a CW Jog Move
can be issued while the CCW limit switch is active. This allows you to move off of an activated end limit
switch.
