HD0 Note:
Acceleration/deceleration method:
Linear acceleration/deceleration
Direction of home return:
- direction of elapsed value
Home input logic:
Input valid when the power is ON
The specified values vary
depending on the method of
acceleration/deceleration, the home
return direction, the home input
logic, and the near home input
logic. (Refer to page 16-7.)
Startup speed (pps) K500 K1 to K4,000,000
Target speed (pps) K10000
K1 to K4,000,000
Specify a value larger than the
startup speed.
Acceleration/deceleration
time(ms)
K100 K0 to K32,767
Note: Home search function is valid.
Note: If the limit error occurs, set H50 as the limit input valid logic can be changed.
Program
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.
-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.
Set the startup speed to 1pps or more.
-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.
-The control code settings vary depending on the logic of the near home input and the home return input
which have been connected.
