CY545 Stepper System Controller

Also note that very slow stepping is possible by a loop that consists of a single-step relative
motion followed by a time delay. For example:
Y 10<cr>
E<cr>
-
N 1<cr>
+<cr>
G<cr>
D 2000<cr>
L 50,16<cr>
0<cr>
Q<cr>
Y 10<cr>
X<cr>
Set to 1 step relative
Select CW direction
Take a step
Delay 2 seconds
Loop back to G command, 50 times
Stop program
Quit entering program to memory
Reset address
Run the program
Select address 10 to start code
Enter to memory
The above example will take 50 steps, with a delay of two seconds between steps. Other delay
values will provide different step rates.
Query Command
Display CY545 Status
Along with display strings, the CY545 allows you to query the values of various working
parameters. The command is:
? Cmd
Query specified parameter value
The “Cmd” portion of the
Query
command is a single letter, selecting the parameter for display.
Possible choices are:
N
P
R
F
S
Y
B
Number of Steps value
Current position value
Current final rate value
Current first rate value
Current slope value
Current memory address pointer value
Current user bits input value
When the Query command is received or read from memory, the CY545 displays the parameter
value as follows:
X=vvvvv<cr>.....ie:.....S=00220<cr>
