23 FFC Feed forward gain:
Set the feed forward gain. When the setting is 100%, the droop pulses
during operation at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline,
when the feed forward gain setting is 100%, set 1s or more as the
acceleration/deceleration time constant up to the rated speed.
When setting this parameter, always set auto tuning (parameter No.

26 TLC 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
the TC of +8V.

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.
