LC - Control Setting Parameters
This provides a low pass lter to the speed command. When the system inertia
has been entered, this setting will be calibrated according to the control mode.
In control modes where the speed prole is generated by the controller (serial,
analog), decreasing the frequency (increasing sample time) may help reduce
any unwanted affects from discontinuous inection points in the speed prole
generated by the controller.

Determines the relative gain of the feed forward torque command. 100% =
unity command. A value of 90% is recommended. Higher values strengthen
the response, lower values weaken the response. When the system inertia
has been entered, this setting will be calibrated.
Provides a low pass lter on the torque command signal before it is fed into
the current control. Lower values can be used to eliminate audible harmonic
sounds which may be heard in the motor.
