The feed forward gain for the position control 
Communication 
address:   
012CH 
012DH 
For smooth change of the position control command, the increase in gain improves the magnitude of the 
following error for the position. For unsmooth change of the position control command, the decrease in gain 
mitigates the vibration of the mechanism during operation. 
 
The smooth constant of the feed forward gain 
for the position control 
Communication 
address:   
012EH 
012FH 
For smooth change of the position control command, the decrease in smooth constant improves the magnitude 
of the following error for the position. For unsmooth change of the position control command, the increase in 
smooth constant mitigates the vibration of the mechanism during operation. 
 
The proportional gain for speed control 
Communication 
address:   
0130H 
0131H 
The speed response is increased when the gain of the speed control is increased. Vibration and noise occurs 
easily if the gain is set to an excessive value.
