Gear Stop
Gear Stop will stop gearing motion that has been initiated from a program.
Example:
Gear.Initiate
Wait for DriveInput.2=ON
Gear.Stop
Gear.Initiate
Gear Initiate will initiate gearing from a program. Gearing will remain active until the Gear.Stop command is used.
Example:
Gear.Initiate
Wait for DriveInput.2=ON
Gear.Stop
Motion Modifiers
Using Last
When the Using Last instruction is inserted after a motion initiate instruction, the time (or master position in synch motion) of the last command complete is used as the starting point of the motion profile. Whenever a motion profile is complete, the time/position is automatically captured behind the scenes. The Using Last instruction simply references this “automatically” captured time or position.
The
If Index0 takes 3 seconds to complete, and Index1 takes 5 seconds to complete, by initiating Index0 and then Index 1 in a program, the user would expect these profiles to take a total of 8 seconds to complete. It is possible though, that because of processor timing, Index.1 does not start at exactly the same time Index0 is complete. Therefore, the two profiles could take slightly more than 8 seconds to complete. Although the amount of time lost is extremely small (less than 5 milliseconds), over a long period of time, this lost time can accumulate.
Keeping the timeline intact is most important in applications using synchronized motion. This is because in synchronized motion, time is replaced by master encoder motion. If time is lost in a synchronized motion application, then master distance is lost, and the follower position is off with respect to the master.
