Basic Move Types (continued)
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 Profile Position while the CCW Jog Move will decrease the Profile
Position. 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.
As shown below, a Jog Moves begins and accelerates at the programmed rate to the Programmed Speed and
continues until a stop condition occurs.
It is possible to change the speed of a Jog Move without stopping the motion. The Programmed Speed, Accel-
eration, and Deceleration parameters can be changed during a Jog Move. When the Programmed Speed is
changed, the motor will accelerate or decelerate to the new Programmed Speed using the new accelerate/
decelerate parameter values.

Controlled Stops

The Jog Move Command bit is reset to “0”.

An inactive-to-active transition on an input configured as a Stop Jog or Registration Move Input.

You issue a Hold Move command in the Network Output Data. This brings the move to an end.
Immediate Stops

You issue an Immediate Stop command through the Network Output Data.

An inactive-to-active transition on an input configured as an E-Stop Input. A Reset Errors command
must be issued before moves are allowed again.

A CW or CWW Limit Switch is reached. A Reset Errors command must be issued before moves are
allowed again.

If set to a non-zero value, the Immediate Stop Deceleration parameter, described on page 26, is used to
decelerate the load.
Note that it is possible to start a move while a CW or CCW Limit Switch is active as long as
the direction of travel is opposite that of the activated Limit Switch. For example, it is possible
to start a CW Jog Move while the CCW Limit Switch is active.
