The control can be equipped with an optional offset jogging feature,

activated by a switch installed by the system installer. When this feature is

active, all jog moves are used to offset the current work coordinate system

and no position registers are changed. See page 4-6 for details.

Only normal single-axis jogs (one axis at a time in the continuous,

incremental, or HPG modes) are permitted during a jog retract operation.

See 7-17.

Important: S--Curve Acc/Dec is not available during manual jogged

motion.

To continuously jog an axis:

1.

Select CONTINUOUS under

<JOG SELECT>

.

2.

Select the feedrate for continuous jog under

<SPEED/MULTIPLY>

.

3.

Press the

<AXIS/DIRECTION>

button for the axis and direction to jog.

The axis moves while the button is held down.

If you want to:

Then:

alter the feedrate selected with
<SPEED/MULTIPLY>

select a <FEEDRATE OVERRIDE> %

jog the axis at a special AMP assigned

traverse feedrate and ignore the setting

<SPEED/MULTIPLY>

press and hold the <TRVRS> when jogging

jog moves that use the traverse feedrate

select a <RAPID FEEDRATE
OVERRIDE>

%

Important: It is possible to jog more than one axis at a time. To jog

multiple axes, press and hold more than one axis direction button. The

selected axes will drive at the feedrate chosen under

<SPEED/MULTIPLY>

.

If the selected feedrate is above a specific axis maximum allowable

feedrate, that axis drives at its maximum feedrate. The feedrate for the

other selected axes is not affected.

Incremental jog manually moves an axis a predetermined amount each
time an

<AXIS/DIRECTION>

button is pressed. To use incremental jog:

1.

Select INCREMENTAL under

<JOG SELECT>

.

2.

Select the jog increment under

<SPEED/MULTIPLY>

. The jog

increment is equal to an amount specified in AMP for each selection

under

<SPEED/MULTIPLY>

.
