Meaning
:
Accesses the numerical input screen.
:
Initializes the system.
:
Returns to the numerical values set one
step previously.
:
Allows you to enter values directly using
the cursor keys.
Operators (For details, see Appendix.3.8.)
For multiplication, always use the "*" sign.
Out of the MOV, SLI, DIF, DIF2, INT, and INT2 operators, up to four can
be used in the same equation (for example four MOV operators or two
MOV and two SLI operator, etc.).
The maximum number of digits for a constant is 30.
If division by 0 is specified (1/0), an overflow value is output.
Equations are calculated in ascending order, from Z1 to Z8.
The data that can be used in an operational equation (channel data and
results of operation) must be smaller than in the preset operation numbers
(for example, Z5 cannot be used on Z4).
Up to eighty characters can be entered in an operational equation. However,
only the first line of the expression is displayed on the waveform operation
screen.
(2) Entering the constant values
1. Move the flashing cursor to
CONST.
2. Use the function keys to select
input
.
The setting range is -9.9999E+29 to
+9.9999E+29 (exponent: -29 to +29).
3. Use the cursor keys or
SHUTTLE
key to move the
cursor. Enter the constant value with the
function key, the
JOG
control or the numerical
input key.
