8.4.30.2 Arithmetic and variables
Values can be linked with one another using the four basic types of calculation and
the result can be assigned to a parameter or a variable.
A simple arithmetic term is:
♦
<Operand> <Operator> <Operand>
♦
P10+10; V1-S1; 2*P13; P13/P14;
V7\V3; S12%P40
♦
<Befehl> <Operand>
♦
POSA .V10; SPEED .V30; ...
Operations are not allowed after commands; use variables instead for such cases,
e.g..
N001: V001= S1 + 100.5 not allowed: POSA S1 + 100.5
N002: POSA .V001
Function Example:
+
for addition P10+10
-
for subtraction V1-S1
*
for multiplication 2 * P13
/
for division P13/P14
\
for whole number division
(formation of the whole number
component)
V7\V3: where V7=30 and V3=7, the result
is:
V7\V3=4
V7/V3=4.2857...; whole number
component= 4
%
for the formation of the division
remainder (Modulo)
S12%P40 with S12=30 and P40=7, the
result is:
S12%P40=2
S12/P40=4 remainder 2; division remainder
= 2
The following operands may be used:
•
constants,
•
parameters,
•
status values, (S1-S15, S30, S40ff)
•
variables (V1-V39); after commands with preceding point (full stop): POSA .V1
Not all status values can be used as operands.
Status values S01 to S15, S30, and S40ff are permitted.
In addition to the 10 user parameters P40 to P49, 39 variables V1-V39 are
available. V0 is used for global assigning of a value to all variables.
The variables are automatically buffer-stored in the ZPRAM, i.e. after Power On
they contain the old value.
When the cam controller is switched off (V50=0), it is possible to use the variables
V51 ... V70 as free variables
After commands the variables (like user parameters P40 to P49) are
preceded by a "point" (full stop): POSA .V1, ACCEL .V22
V0 is used for globally assigning a value to all variables.
Example:
V0=0: V1...V70=0
V0=17: V1...V70=17
With the instruction V0=x, variables V50 ... V70 and therefore the settings of the
cam controller are also changed!
