Loop Bandwidth Units
The Torque Loop Bandwidth attribute determines the Iq Proportional Gain value
that multiplies the Iq Current Error signal before applying it to the Iq decoupling
summing junction as part of the torque producing current loop. In cases where the
torque producing current loop is controlled by something other than the
traditional PI regulator, the Torque Loop Bandwidth is used by the drive to
provide single parametric control of the current loop bandwidth. If the Flux Loop
Bandwidth is not supported, the drive will use the Torque Loop Bandwidth for
tuning both the torque producing and flux producing current loops.
Torque Integral Time Constant

The Torque Integral Time Constant value determines the response time of the
torque producing current loop integrator. When used for Pole-Zero cancelation,
this value is set to the electrical time constant of the motor. A value of 0 for the
Torque Integral Time Constant disables the integrator.
