Loop Gain Fine Adjustment 

Loop Gain Fine Adjustment (Unit: Multiple × 1000) 

Return Value  0: Parameter setting successful 

1: Parameter setting unsuccessful 

This parameter makes fine adjustments to the servo's loop gain (inertia of the motor 
and mirror, and the torque constant of the motor are related). 

Note: This is usually set appropriately at shipping. 

 

 
 

48

Return Value  0: Parameter setting successful 

1: Parameter setting unsuccessful 

This parameter is used to adjust the offset of encoder signal. 

Note: This is usually set appropriately at shipping. 

 

49 

VR head1 A gain 

A-phase amplitude of encoder VR adjustment head 1 (Unit: none) 

Return Value  0: Parameter setting successful 

1: Parameter setting unsuccessful 

This parameter is used to adjust the A-phase amplitude of the encoder signal. 

Note: This is usually set appropriately at shipping. 

 

 

50 

VR head1 B gain 

B-phase amplitude of encoder VR adjustment head 1 (Unit: none) 

Return Value  0: Parameter setting successful 

1: Parameter setting unsuccessful 

This parameter is used to adjust the B-phase amplitude of the encoder signal. 

Note: This is usually set appropriately at shipping.
