4) parameter setting and explanation
a)
PID parameter settings
(1) Scan time (%MW4800)
Scan time is the period of reading data (sampling), and also 10 times scaled up. The range of sampling time is
0.1 ~ 10 seconds, and actual input range is 0 ~ 100. Generally, Scan time of Digital PID control should be less
than 1/10 of time constant of system response for better performance. Time constant is the time taken the
system’s step response reaches to the 63% of steady state.
(2) Operation mode (%MW4801)
Select automatic or manual operating mode
(3) Manual operate range (%MW4802)
When manual operation is designates , manual operation value designates. (input range: 0 ~ 4000)
(4) Output limit value (%MW4803, %MW4804)
Designate minimum and maximum values of available manipulate value. (range: 0 ~ 4000)
(5) Proportional gain (%MW4805)
Indicates the proportional gain. It uses10 times scaled up value. (range: 1 ~ 10000)
