看看32640 STIFFNESS_CONTROL_ENABLE打开没有！
还可能32620打开后32610、32800、32810设太大!

32620 FFW_MODE
0 = No feedforward control
1 = Speed feedforward control with PT1 balancing
2 = Torque feedforward control (only for 840D) with PT1 balancing
3 = Speed feedforward control with Tt balancing
4 = Torque feedforward control (only for 840D) with Tt balancing

MD32610 $MA_VELO_FFW_WEIGHT (factor for the velocity feedforward control)
MD32800 $MA_EQUIV_CURRCTRL_TIME (Equivalent time constant current control loop
for feedforward control)
MD32810 $MA_EQUIV_SPEEDCTRL_TIME (equivalent time constant speed control loop
for feedforward control)
