JOG Positioning Operation
Precautions concerning the program
When Over limit switch (+) and Over limit switch (-) are not connected, change the limit input valid logic
using the control code. The default setting is the input existing when the power is not supplied, that is, is
the input existing without the Over limit switch connection.
- The same shared memory areas to which the various control parameters are written are used for
acceleration/deceleration control, JOG operation JOG positioning operation, home return, and other
types of control.
These should not be overwritten by other conditions.
-Set the position command value in the "Increment" method. A set value error occurs with the absolute
value.
- If the values for the startup speed, the target speed, or the acceleration/deceleration time exceed the
range of values which can be specified, a set value error will occur, and operation cannot be initiated.
- The number of the start flag varies depending on the number of axes the unit has, and the installation
position.
- The specified slot number and shared memory address vary depending on the slot position and axis
number of the positioning unit.
JOG positioning operation start input timing
When the positioning control start input (Timing input) has been already ON when turned ON the JOG
positioning operation start flag (Y_8), the positioning control is immediately started. When the positioning
control start input (Timing input) is turned ON during acceleration, also the positioning control is
immediately started.
When the positioning control start input (Timing input) does not go ON after the JOG positioning
operation started up, the pulses keep going out.
