Note:

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	V7\V3: where V7=30 and V3=7, the result
	(formation of the whole number	is:
	component)	V7\V3=4
		V7/V3=4.2857...; whole number
		component= 4
%	for the formation of the division	S12%P40 with S12=30 and P40=7, the
	remainder (Modulo)	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-V39are 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

Variable	Global assignment:
voltage

Note!

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!
