Speed Limit Function
In the torque control mode, the torque command input from the upper level controller controls the
torque, but does not control the speed; thus, the apparatus might be damaged due to exceedingly
increased speed by an excessive torque command. To address this problem, this drive provides a
function that limits motor speed based on the parameters set during torque control.
You can limit the speed using the maximum speed or the speed limit value (0x230E) according to the
value of the speed limit function setting (0x230D), as described below. With the output value of VLMT
(speed limit), you can verify if the speed is limited.
