12 CONTROL AUXILIARY FUNCTIONS
12.4 Functions to limit the control
Functions to limit the control include the "speed limit function", "torque limit function",
"software stroke limit", and "hardware stroke limit". Each function is executed by
parameter setting or sequence program creation and writing.
12.4.1 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".
