Variables

DOK-ECODR3-FL*-04VRS**-FK01-EN-P
The commands contain data which are subsets of the instruction.
These constants can also be changed on-line via the serial interface, but
not from the user program.
Using variables is an alternative for using constants. They can be
programmed in place of the constants, so that this data can also be
edited from the user program.
The variables are retained and all have the same format:
+12345678.123456
If a variable is used in a command, only the size of the constant that has
been placed here is used. If the content of the variable is greater or less
than the size of the constant, an error message is generated.
Note: The variable's operational sign is always taken into account!
e.g.
For a travel command POI, several inputs are shown.
With Constants:
POI 1 +123456.123 111
For feed length, the following data size is assigned min.: -200000.000
For velocity, the following data size is assigned
V600 = +00123456.123456
V601 = +999.9999
V602 = +01234567.123456
V603 = -999.99999
V604 = -1234.123456
POI 1 +V600 V601
The value +123456.123 is picked up from the variable V600.
The value 999 is picked up from the variable V601.
POI 1 +V602 V603
The value of variable V602 is too large. An error message is
generated.
The value of variable V603 is negative. An error message is
generated.
POI 1 -V604 V601
The content of variable V604 is negative. With the operational
sign from the command, the feed length becomes positive.
