PID CONTROL INSTRUCTION
11.1
PID Control Loop
PID
This instruction executes PID control which changes the output value according to the input variation.
Setting data
■
Descriptions, ranges, and data types
*1 When setting using a label, use the global label assigned to the device.
■
Applicable devices
*1 Only D, SD, R can be used.
Processing details
When the target value (s1), measured value (s2), and parameters (s3) to (s3)+6 are set and a program is executed, the
operation result (MV) is stored to the output value (d) at every sampling time (s3). For details, refer to the
MELSEC iQ-F
FX5 User's Manual (Application).
