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