◼ Filter time constant of torque instruction
When machine vibration may be caused by servo drive, it is possible to eliminate vibration by adjusting the
filtering time parameters of the following torque instructions. The smaller the numerical value, the better the
response control can be, but it is restricted by the machine conditions. When vibration occurs, the parameter is
generally reduced, and the adjustment range is suggested to be 10-150.
◼ Model loop gain
When the model loop is valid (P2-47.0=1), the response of the servo system is determined by the gain of the
model loop. If the gain of the model loop is increased, the responsiveness is increased and the positioning time is
shortened. At this time, the response of the servo system depends on this parameter, not P1-02 (position loop gain).
The gain of the model loop is only valid in position mode.
