9-1 Jogging
This section describes the JOG operation and the data needed for performing
it.
9-1-1 Outline of Operation
While JOG is ON, axis operation is started using the designated direction,
speed, and acceleration time. When it is turned OFF, positioning decelerates
with the designated deceleration time and then stops. The JOG operation can
be executed even when the origin has not been established.
9-1-2 Procedure for Executing JOG
1,2,3... 1. Set the operating data area using the parameters.
2. Set the speed and acceleration/deceleration times in the operating data ar-
ea.
3. Designate the start direction in the operating memory area.
4. Turn ON the JOG Bit. If the initial speed is set in the parameters, it will be
in effect.
9-1-3 Beginning Words of Memory Areas
The beginning words of the operating memory area, operating data area, and
common parameter area used for a Position Control Unit (PCU) are deter-
mined (or set) according to the following.
• Beginning word of the operating memory area, n = CIO 2000 + 10

• Beginning word of the operating data area, l, is specified in m and m+1.
Set the beginning words of the operating data area and designate the axis
parameters used with the common parameters as shown below.
