LT360 Precision Turntable
DLL Programming Manual
2.22 Set Output Mode
■ Class Set (out)
■ Identifier lt_SetOutputMode
■ Hex Value 0x3B
■ Call LT360LIB_CmdValue(Handle, lt_SetOutputMode, 'xxxx');
■ Parameter 'CONT' or 'START' or 'STOP'
Description
This command selects the operating mode for the Analog Output. The
parameter string value is either CONT or START or STOP.
When CONT is the mode, the Analog Output will continuously follow the
platter position as it is moving. This is a real time output mode where the
analog output voltage always represents the current platter position.
When START is the mode, the Analog Output will only produce a single step
change output voltage representing the final destination position at the start
of the movement. For example, if the current position is 0.0 degrees and
the destination is 100.0 degrees, the Analog Output voltage will change
from 0.000V to 1.000V at the start of the movement.
When STOP is the mode, the Analog Output will only produce a single step
change output voltage representing the final destination position after the
movement stops. For example, if the current position is 0.0 degrees and
the destination is 100.0 degrees, the Analog Output voltage will remain at
0.000V during the movement and then change to 1.000V when the move-
ment stops. The final output voltage changes 2 seconds after the platter
movemet stops.
If the movement is aborted before it reaches the destination, the output
voltage will be updated to the correct final value in all modes.
