Example: Command All MicroSpeed 196 units to Stop
Message Sent- stx00000l00000etx
Message Returned- stx00l00l00000etx
Command Message Type Definitions:
Start - 0 - Starts the specified MicroSpeed 196. If the front or back panel stop has been
enabled (with Var 30) and Stop is held, this command will be ignored.
Stop -1 -
Stops the specified MicroSpeed 196.
E-stop - 2 - E-stops the specified MicroSpeed 196.
Set to Factory Defaults - 3 -
Sets all variables, except Node Address (Var 19) and
Baud Rate (Var 20), to the default values.
Set Point Changes:
Only the active set point can be changed via commands 4 - 8. To change a nonselected
set point, use the write message type. The decimal location is fixed by Variable 02 in
the Master mode or Variable 23 in the Follower mode. You cannot write to the active
set point’s variable while running.
Change Set Point - 4 - Changes the presently selected set point to the value sent.
Load Master Set Point - 5 - Allows for a new speed set point to be loaded, but not
executed. The value will be stored in Variable 49.
Execute Master Set Point - 6
-
Moves the loaded speed set point into the active set
point (1 - 4), and ramps to the new value.
Load Follower Set Point - 7 - Allows for a new ratio set point to be loaded, but not
executed. The value will be stored in Variable 49.
Execute Follower Set Point - 8 -
Moves the loaded ratio set point into the active set
point (1 - 4), and ramps to the new value.
Error Message - 3 -
If the MicroSpeed 196 detects an error in a message, it will
respond with a 3 in the Character #4 position. The type of error will be specified in the
Character #6 position.
