2.5.4 ManualJog
In ManualJog the drive/tool can be moved by means of manual operator inputs. This type of
operation may be required, for example, to clean or change a tool.
In this context it is important that when functioning in manual mode, the drive moves in "inching
mode" but does not follow the cam (or motion profile). ManualJog movement is not determined
by the motion profile (cam) but follows linear speed curves independently of the profile. In this
operating mode, a master value entry and the cam function will have no effect on drive motion.
In ManualJog, the g_bGlobalError global variable is evaluated. Setting the g_bGlobalError
global variable to TRUE during ManualJog in a positive or negative direction will stop the drive
on the quick stop ramp. By resetting the error (g_bGlobalError=FALSE) the drive direct start
moving in the selected direction as long as there is a signal for manual movement. There is no
new positiv edge necessary to restart the manual movement.
