1. Give the AL XYZW command or ABCDEFGH for DMC-4080, to arm the latch for the main encoder and
ALSXSYSZSW for the auxiliary encoders.
2. Test to see if the latch has occurred (Input goes low) by using the _AL X or Y or Z or W command.
Example, V1=_ALX returns the state of the X latch into V1. V1 is 1 if the latch has not occurred.
3. After the latch has occurred, read the captured position with the RL XYZW command or _RL XYZW.
Note: The latch must be re-armed after each latching event.
Example:
#Latch Latch program
JG,5000 Jog Y
BG Y Begin motion on Y axis
AL Y Arm Latch for Y axis
#Wait #Wait label for loop
JP #Wait,_ALY=1 Jump to #Wait label if latch has not occurred
Result=_RLY Set value of variable ‘Result’ equal to the report position of y axis
Result= Print result
