6.2.4 PID Configuration Parameters
51
INTEGRAL TIME (0000 sec, 3600 secs)
It can be changed by the user. When Tune operation stops, it can be
changed by the device. If it is 0, integral control part does not run. When
tune operation stops if this parameter is 0, this parameter can not be
changed because of integral control part does not run.
DERIVATIVE TIME (000.0 sec, 999.9 secs)
It can be changed by the user. When Tune operation stops, it can be
changed by the device. If it is 0, derivative control part does not run.
When tune operation stops if this parameter is 0, this parameter can
not be changed because of derivative control part does not run.

PERIOD
Relay Output :
Output period must be short for stable process control.
Relay must not be used in short output periods because of limited life of
their relay contact (number of open/close events). Relay output must
be used as control output in values near to 30 seconds or greater than
this value.
SSR Output :
If short output period is needed in a system
(approximately 1-2 seconds) SSR driver output as last control element
is recommended.
CONTROL PERIOD TIME (1 sec, 150 secs)
It is control period
PROPORTIONAL BAND ( 000.0% , 999.9% )
Full Scale ( - ) %.
If = 1000 °C, = 0 °C and = 50.0 then
Proportional Band = ( - ) * / 100.0
Proportional Band = (1000-0)*50.0/100.0 = 500 °C
