Why use the Motion Profile Table?
The PLC can issue only a Command and Command Value in a single command cycle.
Therefore, the Go command can only give the Requested Position as the command value,
so to set the entire motion profile and give the Go command would require five
commands. While this is flexible, it requires a great deal of programming and run-time.
By using the Motion Profile Table, a complete move including all four motion profile
fields can be set with a single Go Using Profile command, speeding up both execution
and development time.
How is the Motion Profile Table Used?
The Go Using Profile and Open Loop Using Profile commands select one of the 16
motion profiles in the table and use that profile to issue the command.
How is the Motion Profile Table Changed?
There are two ways to the change the motion profiles table:
• Use the Motion Profile Table Editor. On the Tools menu, click Profile Editor to start
this editor; see Editing the Profile Table for details.
• Use the Set Profile commands to change the table from the PLC.
How do I Save the Motion Profile Table?
There are three places where the Motion Profile Table can be saved:
• FLASH memory. Use the Update FLASH command to store the current profile table
in the FLASH memory.
• Disk file. The table can be saved to disk from within the Motion Profile Table Editor .
• PLC memory. Use the Set Profile and Get Profile commands to send the table to and
from the PLC.
What are the Default Motion Profile Values?
When the motion controller starts, it first does a checksum on the profile table in the
FLASH memory. If the FLASH-stored profile table checksum is correct, it is used. If
the checksum is incorrect, then the following default profiles are used:
Profile 0 1 2 3
MODE 0 0 0 0
ACCEL 1000 2000 5000 8000
DECEL 1000 2000 5000 8000
SPEED 1000 2000 5000 8000
Profile 4 5 6 7
MODE 0 0 0 0
