13.4 Functions to limit the control
Functions to limit the control include the "speed limit function", "torque limit function",
"software stroke limit function", "hardware stroke limit function", and "forced stop
function". Each function is executed by parameter setting or sequence program
creation and writing.
13.4.1 Speed limit function
The speed limit function limits the command speed to a value within the "speed limit
value" setting range when the command speed during control exceeds the "speed limit
value".
The details shown below explain about the "speed limit function".
