Exercise 2: Sensor Input I
Here we pretend the potentiometer is a pressure transducer and use it to display
a pressure value to the screen.
ADS 1=50.5,1 ‘set ADS to aunit=50.5,analog input mode
PGM 200
LBL PRNTPSI ‘name program “PRNTPSI”
PRINT "\e[2J" ‘ansi esc. to clear display
PRINT "Pressure = ", AIN 1 , " PSI"
BR PRNTPSI ‘loop to program beginning
END
PGM
Exercise 3: Sensor Input II
Once again our potentiometer is pretending to be a sensor. In this exercise the
program will call up a subroutine based upon the voltage seen on AIN 1 and
position the axis at an absolute position. The best analog to this exercise might
be a flow control application.
'****Parameters****
MUNIT=51200 ‘munits=51200
MAC=75 ‘acceleration current to 75%
MRC=50 ‘run current to 50%
ADS 1=5,1 ‘aunits 5, analog input mode
VAR LIMIT=0 ‘declare user var “LIMIT”
'****Program****
PGM 200
LBL AINTST ‘name program “AINTST”
LIMIT = AIN 1 ‘set user var “LIMIT” = AIN 1
CALL ATEST, LIMIT>3.5 ‘call ATEST if LIMIT is greater than 3.5 aunits
CALL BTEST, LIMIT<3.5 ‘call BTEST if LIMIT is less than 3.5 aunits
BR 200 ‘loop to beginning of program
END
'****Subroutines****
LBL ATEST ‘declare subroutine “ATEST”
VM=20 ‘max. velocity = 20 munits/sec.
MOVA 10 ‘index to abs. pos. 10
HOLD 2 ‘suspend prog. until motion completes
RET ‘return from subroutine
LBL BTEST ‘declare subroutine “BTEST”
VM=5 ‘max velocity = 5 munits/sec.
MOVA 22 ‘index to abs. pos. 22
HOLD 2 ‘suspend prog. until motion completes
RET ‘return from subroutine
