Attention 
Analog speed limit input voltage has no polarity. + oltage or – voltage are received as an 
absolute value. The speed limit of this absolute value is applied to forward and reverse 
direction. 
 
Even if Analog Speed limit is 0V, the Motor may rotate slowly; this is mainly caused by the minor 
Offset of External Analog Voltage. In this case, the user can manually adjust Sn217 to correct the 
offset or use Automatic Adjustment. Please refer to “3-3 Diagnostic Function Description”. 
 
 
Attention 
Please confirm the status is Servo off before adjustment; Input 0V voltage command from the 
supervisory controller or external loop to analog command connect SIC (CN-1-26).

0  mV  -2500 ~ 2500  Effective after Set  0211H 
Setting Description:  Used to correct offset when the Analog Speed Command Voltage generates the 
offset phenomenon. 
 
Add a filter to the analog speed command (SIC) to smooth the speed command. The analog speed 
command filter is set by Sn226. When the set value is too low, the response of the speed command 
may decrease. Please confirm the response while setting.
