Stroke ratio data type
The following are set in the stroke ratio data type. Set these in the cam setting window of MR Configurator2. When "Cam No."
is set to "0", straight-line control is performed so that the stroke ratio at the last point of the cam data becomes 100%.
The following is a setting example for "cam resolution = 512" in the stroke ratio data type.
• Feed current value
The feed current value of the cam axis is calculated as follows:
Feed current value = Cam standard po (Cam stroke amount × Stroke ratio to cam axis current value per cycle)
When the cam axis current value per cycle is in the middle of the specified stroke ratio data, the intermediate value is
calculated from the cam data before and after the value.
