↓

Enter the programming mode

S10

↓

Set the Start-stop rate to 100

steps/sec.

T100

↓

Set the Slew speed rate to 1000

steps/sec.

R50

↓

Set the Ramp length to 50 steps.

G500000

↓ Goto the target position

↓

End of the programming session.

The GS-C starts the program exe-

cution.

The G500000 command can be substituted by the

+500000 command. The program can also be

stored in the GS-C EEPROM by typing an M

↓

command before the E

↓ command.

Example 2

The program chosen for this example drills 5 equi-

distant holes on a metal bar. A GS-C and GS-D

motion system is used to control the vertical posi-

tion of the drill, while a second GS-C and GS-D

motion system is used for the proper bar loading

and positioning. To better clarify the operations to

be executed and to show the program simplicity, the

two command sequences and the relative process

flowcharts are also reported.

The programming session is entered following the

points 1 to 4 of the previous example. The first

command sequence, used to correctly position the

metal bar, is the following:

S10

↓

Set the Start-stop speed to 100 steps/sec

T100

↓

Set the Slew speed to 1000 steps/sec

R40

↓

Set the ramp length to 40 steps

↓

Wait for the external Start

+250

↓

Reach the first drilling position

↓

Loop starting point

↓

Activate the unit 2 forcing UO2 = 1

↓

Wait 0.1 sec

↓

Then reset UO2

↓

Wait until drilling completion

+120

↓

Reach the drilling position 120 steps CW

↓

Repeat the loop 4 times

↓

Activate the unit 2 forcing UO2 = 1

↓

Then reset UO2

↓

Wait until drilling completion

+250

↓

Reach the cutting position 250 steps CW

↓

Activate the cutting blade forcing UO1 = 1

↓

Wait 0.5 sec

↓

Clear cutting command resetting UO1

The second command sequence, used to drill the

metal bar, is the following:

S15

↓

Set the Start-stop rate to 150 steps/sec

T200

↓

Set the Slew rate to 200 steps/sec

R25

↓

Set the Ramp length to 25 steps

↓

Wait for start

↓

Wait for a drilling command from unit 1

↓

Activate the drill motor forcing UO2 = 1

+150

↓

Pull down the drill

↓

Wait 0.1 sec

↓

Lift the drill up

↓

Stop the drill motor

↓

Notify drilling completion to unit 1 forcing

UO1 = 1

↓

Wait 0.1 sec

↓

Then clear UO1

The combination of these two programs operates

only on one bar, then the two GS-C become avail-

able again to the Host both for the repetition of the

program or for the entering of a new command

sequence.

If the operation has to be repeated till the exhaus-

tion of bars, it will be sufficient to add, at the

beginning of the first sequence, the command;

↓

execute until UI3 = 1

which allows the drilling cycle to continue until the

controller which takes care of the bar positioning, is

notified to stop the operations.

This notification is accomplished by clearing the

User input UI3 of GS-C devoted to the positioning.

To demonstrate the efficiency of the GS-C program-

ming language it is worth to mention that the pro-

gram for the bar positioning uses 50 memory

locations, while the program for the drill control

needs only 36 memory locations. The two programs

can be contained in the GS-C memory thus making

the system simpler and easier to maintain.
