SPECIFICATIONS
1. Control system configuration
There are two methods of control system configuration
for CC-S, one is configuration by Basic PID and the other
is by wafer connection.
Various types of configuration examples are shown
"VARIOUS CONTROL EXAMPLES" stated hereafter.
(1) Configuration by basic PID (fixed configuration)
Basic PID control function is fixedly defined as standard control function in the controller beforehand.
Configuration of basic PID can be performed through
simple operation on the front panel keys, where wafer
connection mentioned below is unnecessary.
Computation wafers such as square root, filter, Iimiter,
non linear, etc. can be made valid or invalid by simple
operation of front panel keys.

VARIOUS CONFIGURATION EXAMPLES
Basic PID control (Fixed configuration)
Basic PID control function is
fixedly defined as standard control
function in the controller
beforehand. Configuration of
basic PID can be performed
through simple operation on the
front panel keys, where wafer
connection is unnecessary. Computation functions such as square
root, filter, limiter, non linear, etc.
can be made valid or invalid by
simple operation of front panel
keys.
PID control
PID control is carried out by using
only the MAln control block. PID
control by means of an external
set point is also performed.
