Feed forward gain:
Used to set the fee forward gain.
When it is set to 100%, droop pulses will not be generated in
constant-speed operation. Note that sudden acceleration/deceleration
will increase overshoot.
When setting this parameter, always set auto tuning (parameter No.

Analog torque command maximum output:
Used to set the output torque at the analog torque command voltage
(TC =
±
8V) of +8V on the assumption that the maximum torque is
100[%]. For example, set 50 to output (maximum torque
×
50/100) at

Internal torque limit 1:
Set this parameter to limit servo motor-generated torque on the
assumption that the maximum torque is 100[%]. When 0 is set,
torque is not produced.
