Note 1. The actual integral and derivative times are calculated using the values set
in C+2 and C+3 and the time unit set in C+6.
2. Setting the 2-PID parameter (α) to 000 yields 0.65, the normal value.
3. The only CQM1 model that can use PID(––) is the CQM1-CPU4j-EV1.
--- Target value filter-type, two degrees of freedom (forward/reverse
operation)
--- No limit (1 loop per instruction)
t 0.01 to 102.3 s (See note.)
P 0.1 to 999.9%
Tik 1 to 8191, 9999 (No integral operation for sampling period multiple or
9999.)
Tdk 0 to 8191 (No derivative operation for sampling period multiple.)
SV 0 to 65,535 (Valid up to the maximum value of the input range.)
PV 0 to 65,535 (Valid up to the maximum value of the input range.)
MV 0 to 65,535 (Valid up to the maximum value of the output range.)
Note For the C200HS and the CQM1-CPU4j-EV1, the sampling period is 0.1 to
102.3 s.
