Automatic Operation (Position Control)

8.1 Basic Operation

8.1.1 Patterns of Position Control

• The automatic operation is an operation mode to be perform a position control. For the
position control, there are a single axis control and an interpolation control that starts and
stops multiple axes simultaneously.
• For the operaions of position controls, there are E-point, P-point and C-point controls which
are performed regardless of single axis control or interpolation axis control. Also, there is J-
point control which is activated only by the single axis control. The operation patterns of
each control are as follows.

Operation and application
 This is a method of control which is
initiated up to an end point, and is
called "E-point control".
 This method is used for a single-
speed acceleration/deceleration.
 This refers to control which passes
through a "Pass Point", and is called
"P-point control".
 This method is used for performing
acceleration/deceleration by two-
t
speed control or more.
 After the P-point control is
performed for a specified movement
amount, it shifts to the E-point control.
 The last table should be set to E:
End point.
t
 This refers to control which passes
through a "Continuance Point", and is
called "C-point control".
 This method is used for performing
two successive single-speed
positioning control with different target
t
speeds or acceleration/deceleration
times.
 The time taken until the operation
shifts to the next table is specified as
a dwell time.
 The last table should be set to E:
End point.
