Hexadecimal: 044
Command Value: New DECELERATION value (units depend on Accel/Decel
Mode in the MODE word)
This command sets the DECELERATION parameter to the value in the COMMAND
VALUE field. The change in deceleration takes place immediately if a move is in
progress.
Start Events Command
Character: E
Decimal: 69
Hexadecimal: 045
Command Value: Event Step to Start Execution
This command starts an event step sequence at the step specified in the COMMAND
VALUE field. If the axis already was in the middle of an event sequence, that sequence
will end and the new event sequence will begin.
Set Feed Forward Command
Character: F
Decimal: 70
Hexadecimal: 046
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.
Go Command
Character: G or g
Decimal: 71 or 103
