15.1.2 Features
The built-in PID control functions of XGB series feature as follows.
(1) Since operations are executed within CPU part, it can be controlled by PID parameters and PLC
program without PID module.
(2) A variety of controls can be selected
â–ª That is, a user can easily select P operation, PI operation and PID operation.
(3) Precise control operation
â–ª It can make precise PID control operations possible through floating point operations.
(4) PWM (Pulse Width Modulation) output available.
â–ª It outputs control operation results to the output contact point designated by a user through PWM.
(5) Improving convenience of control settings and monitoring
â–ª Through parameter setting method and K area flag, it maximizes control parameter settings
during operation and convenience of monitoring
(6) Freely selectable operation direction
â–ª Forward, reverse and mixed forward/reverse operations are available
(7) Cascade operation realizing quick and precise PID control
â–ª It can increase quickness of response to disturbance through cascade loop.
(8) Various additional functions
â–ª PID control can be achieved by various methods a user wishes because set value ramp, the
present value follow-up, limiting change of values and types of alarm functions are provided.
