5.7.8 Torque command filter

5.7.8.1 Function restriction

Set the control mode (P1.001.YX) to Torque mode (T or Tz).

5.7.8.2 Function description

After the torque command is processed with the first-order low-pass filter, the unwanted

high-frequency response or noise is attenuated, and the command becomes smoother.

5.7.8.3 Application example

When the servo is in analog Torque mode (T) to perform force control (such as tension or

pressure control), the command value is usually a constant which changes slowly. Since the

bandwidth of the servo current loop is much higher than that of the position loop and speed

loop, it is highly responsive but is subject to noise interference. Properly adjust P1.007 to

reduce the high-frequency noise and increase the control accuracy.
