Speed control mode
235
Programming:
Configuration:
P93 = +4 i.e. speed control operating mode
P94 = +2 i.e. smooth ramp shape
Names of the inputs and outputs:
I7 light barrier 0 # not activated 1 # activated
I8 shutter 0 # open 1 # closed
I9 interlock 0 # open 1 # closed
I10 operating mode 0 # remove 1 # centrifuge
O7 interlock 0 # closed 1 # open
List of programs:
N001: ACCEL 10 000......................................... ;sets the accelerating and braking ramps to 10s
N002: IF I8=1 GOTO locks (5) ........................... ;checks whether the shutter is closed
N003: OUTPUT O7=1 ........................................ ;opens interlock
N004: IF I8=0 GOTO 4....................................... ;waits until the shutter is closed
Lock:............................................................. ;mark
N005: OUTPUT O7=0 ........................................ ;closes interlock
N006: IF I9=0 GOTO 6....................................... ;checks whether interlock is closed
Operating mode query:
N007: IF I10=1 GOTO centrifuges (18).............. ;queries operating mode switch
Remove:....................................................... ;mark
N008: SPEED 0.1............................................... ;sets the speed to 0.1%
N009: WAIT 500................................................. ;waits 500 ms
N010: IF I7=0 GOTO 10..................................... ;waits until the light barrier is activated
N011: SPEED 0 ................................................. ;sets the speed to 0
N012: OUTPUT O7=1 ........................................ ;opens interlock
N013: IF I8=1 GOTO 13..................................... ;waits until shutter is opened
N014: IF I8=0 GOTO 14..................................... ;waits until shutter is closed again
N015: OUTPUT O7=0 ........................................ ;closes interlock
N016: IF I9=0 GOTO 16..................................... ;checks whether interlock is closed
N017: GOTO operating mode query (7)............. ;goes to data record N007
Centrifuge:.................................................... ;mark
N018: SPEED 100.............................................. ;sets speed to 100%
N019: IF I10=0 GOTO removing (8)................... ;operating mode query
N020: GOTO 19 ................................................. ;goes to data record N019
