Character: F
Decimal: 70
Hexadecimal: 0x46
Command Value: Unused
The 'F' command is used to automatically set the feed forward values. After a move is made where the axis is allowed to reach constant velocity and the overdrive bit is not set, an 'F' command will set the Feed Forward for the direction last moved. This command is quick and easy, and it allows the system to adjust for changing system dynamics. This also makes setup easier.
Note: The 'F' command should be used only after the axis is moving smoothly. If the axis oscillates or doesn’t reach steady state during the move, this command will give erroneous results.
If the Null Drive is not adjusted correctly, the value for the Feed Forward will be incorrect.
