When an input value that is 0 or the cam axis length per cycle does not exist in the coordinate
data, the coordinate is calculated from the line segment between the nearest two coordinates.
(Cam reference position)
(4) Auto-generation data format
A cam pattern is created based on the specified parameter (data for auto-generation).
Control cam data is created in the stroke ratio data format in the cam open area.
Therefore, the operation specification during the control conforms to the cam using the
stroke ratio data format.
The types of cam patterns for auto-generation data format are as follows.
Cam for rotary cutter
If the cam data is set incorrectly, similarly to the incorrectly setting of a target value and command
speed in the positioning control, the position and speed command to the servo amplifier increases, and
may cause machine interface and servo alarms such as "Overspeed" and "Command frequency error".
When creating and changing cam data, execute a trial operation and provide the appropriate
adjustments.
Refer to "Safety precautions" for precautions on trial operations and adjustments.
