6.7.2.5 Rate Limiting in Velocity-Mode
The T200 provides a means of limiting the rate of change of the velocity command. This limits the acceleration (rate of
change of velocity) which a sensitive load may experience during acceleration and deceleration phases of a motion.
The user can program the Velocity Rate Value (specified in RPM) and the Velocity Rate Time (specified in seconds).
The maximum allowable rate of change of actual velocity is then given by:-
