Page 11: Overview
1 OVERVIEW MELSEC-Q 1 OVERVIEW This manual describes the process control instructions equipped for the QnPHCPU/QnPRHCPU. 1.1 Features The process control instructions have the following features. (1) Use of floating-point data Capable of handling floating-point type real number data, the instructions can perform wide- range and accurate operations.
Page 12 1 OVERVIEW MELSEC-Q (3) Free combination of process control instructions for application to a wide range of control As an option, a process control instruction can be inserted in a loop that links process control instructions. Add the square root operation instruction (S.SQR) to perform the square root operation of an input signal to provide an output signal as shown below.
Page 13 1 OVERVIEW MELSEC-Q (5) PID algorithm using a velocity type incomplete differential format Partial differential has the following advantages over the complete differential format. (a) The differential gain is 1/ and the limit value can be set. (b) The output contains time amplitude, so the system actually responds to the operation edge so the derivative operation makes the movement valid.
Page 14: Pid Control Overview
1 OVERVIEW MELSEC-Q 1.2 PID Control Overview PID control is applied to the process control of flow rate, speed, air volume, temperature, tension, compounding or like. In a configuration shown in Fig. 1.1, PID control maintains the object to be controlled at a preset value.
Page 15: Forward Oprration And Reverse Operation
1 OVERVIEW MELSEC-Q 1.3 Forward Operation and Reverse Operation (1) Forward operation is the action that increases the manipulated value when the process value increases more than the set value. (2) Reverse operation is the action that increases the manipulated value when the process value is decreasing more than the set value.
Page 16: Pid Control
1 OVERVIEW MELSEC-Q 1.4 PID Control This section explains "proportional operation", "integral operation" and "derivative operation" performed for PID control using the process control instructions. 1.4.1 Proportional operation (P operation) This section explains the control method using proportional operation. (1) Proportional operation is the action that compares the deviation (difference between the set value and the process value) to find the manipulated value.
Page 17: Integral Operation (I Operation)
1 OVERVIEW MELSEC-Q 1.4.2 Integral operation (I operation) This section explains the control method using integral operation. (1) Integral operation is the operation that continuously changes the manipulated value to eliminate deviation when there is deviation. This operation can eliminate the offset that occurs during control performed by a proportional operation.
Page 18: Derivative Operation (D Operation)
1 OVERVIEW MELSEC-Q 1.4.3 Derivative operation (D operation) This section explains the control method using the derivative operation. (1) The derivative operation is an operation that adds the proportional manipulated value to the change speed to eliminate deviation when a deviation has occurred. The derivative operation can prevent large changes in the object control from disturbances.
Page 19: Pid Operation
1 OVERVIEW MELSEC-Q 1.4.4 PID operation This section explains the control operation using combinations of proportional operation (P operation), integral operation (I operation), and derivative operation (D operation). (1) The PID operation controls the calculated manipulated value using (P D) operation. (2) The PID operation when the deviation is a constant value stepped response is shown in Fig.
