AXIS#.IL.KVFF
Description
This parameter sets the gain for the velocity loop feedforward. It is used when you want to add a pure torque
Torque is the tendency of a force to rotate an object about an axis. Just as a force is a push or a pull, a torque can be thought of as a twist component scaled by the velocity command.
Resulting TorqueTorque is the tendency of a force to rotate an object about an axis. Just as a force is a push or a pull, a torque can be thought of as a twist Feedforward = AXIS#.VL.CMD * AXIS#.IL"Instruction list"
This is a low-level language and resembles assembly.KVFF
This parameter is only used in velocity and position mode (AXIS#.OPMODE = 1 and 2).
