5.4 Positioning Control5-155.4 Positioning Control5.4.1 Types of Positioning Control Operation patternName Time chart Operation and application Repeat Interpo-lationE-pointcontrolt[ms]f[Hz]E This is a method of controlwhich is initiated up to an endpoint, and is referred to as “E-point control”. This method is used for a firstspeedacceleration/deceleration. P-pointcontrolt[ms]f[Hz]P E This refers to control whichpasses through a “Pass Point”,and is called “P-point control”. This method is used for asecond speedacceleration/deceleration. After the pulse output isperformed for a specifiedmovement amount, it shifts tothe E-point control. C-pointcontrolt[ms]f[Hz]C E This refers to control whichpasses through a “ContinuancePoint”, and is called “C-pointcontrol”. This method is used forperforming two successive firstspeed positioning control withdifferent target speeds oracceleration/deceleration times. The time taken for transmittingfrom the C-point control to E-point control is specified as adwell time. J-pointcontrolNo speed changet[ms]f[Hz]J E This refers to control whichpasses through a speed point“JOG Operation Point”, and iscalled “J-point control”. After the start, it is controlled atspecified speeds. Once the J-point positioningcontact turns on, the positioningcontrol starts. When the J-point controlspeed change flag is set, thespeed changes.- -Speed changest[ms]f[Hz]J E
