Constant-Speed Control

[Procedure to Write Servo Programs]
Downloaded from ManualsNet.com
(1) After a single control start, positioning control is executed using the designated
positioning method and positioning speed to the preset pass point.
(2) The positioning method and positioning speed can be changed for each pass
point.
(3) Set the following parameters with the servo program.
• pass point
• positioning method from one pass point to the next pass point.
• positioning speed from one pass point to the next pass point.
(4) Repeat instructions permit repeated control between any pass points.
(5) M-code and torque limit value can be changed at each pass point.
(6) From one to 4-axes can be controlled.
The method to write servo programs for constant-speed control is shown below.
