Even if Analog Speed Command 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 the 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).

Initial Value Unit Setting Range Effective RS-485 Address
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.
