Jog Speeds 1 And 2 (Modes 1,2) - Siemens SIMATIC S5 Manual

4.2.1

JOG Speeds 1 and 2 (Modes 1,2)

In these two operating modes, you can move an axis at a constant speed. The basic speeds
themselves are contained in the machine data. You can traverse at JOG speed 1 or 2 by entering
a "0" in the speed parameter.
After selecting one of the two operating modes, you can start an axis moving in the required
direction by setting the commands "forward" or "reverse". By pressing the stop key on the PG
you can stop the axis again. From the programmable controller's side, FB164 provides a special
feature. On the signal edge of the "forward" or "reverse" command from O to 1, the axis is moved
in the selected direction and is stopped again when the signal changes from 1 to O. The axis also
stops if a stop command is entered (=> Section 6.2.9.2 "Special Features of the Parameters

You can also switch from one jog speed to the other while the axis is moving. The axis then
stops and continues its movement in the new jog mode.
In the jog mode (BA 1 and 6A 2) and in the incremental mode (BA 6 and 6A 7), you can traverse
at speeds different from those in the machine data, by entering a value between 1 and 65000 in
the speed parameter, Values outside this range are restricted to the limit values. The traversing
movement is then executed at the limit speed. You cannot change the speed while the axis is
moving.
