Chapter 15 The PID function of K200S MASTER-K
15-18
10) BIAS
The BIAS data is used for the compensation of offset in the proportional control. The
range is 0 ~ 4000.
11) SV (Set value)
SV (setting value : the designated value) and PV (process value : present value) of
K200S PID operation have the range 0 ~ 4000. The range is set with the consideration of
the resolution of A/D and D/A module of K200S series (12 bits) and offset value.
12) F/R (Forward / reverse operation)
The operation mode (forward or reverse) can be set with F/R word. If the value of F/R is 0,
the PIDCAL instruction performs forward operation. If the F/R is 1, reverse operation is
performed.
13) STAT
The PIDCAL instruction output a relevant error code when an error occurs during PID
operation. See the chapter 15.4.3 error code list for details
14) MV (Manipulation value)
The result of PID calculation is output to this word.
The other control modes other than P, PI, PID, and On/off operation are not allowed. For
example, PD or I operation is not available.
