Set the compensation amount with SV031 (OVS1) and SV042 (OVS2). 

00: Overshooting compensation stop 

10: Setting prohibited 

01: Setting prohibited 

11: Overshooting compensation type 2

 

 

 

 

 

 

 

 

Set the compensation amount based on the motor’s stall current. 

Increase by 1% and determine the amount that overshooting doesn’t 
occur. When OVS2 is "0", setting values in both of the + and –directions 
are applied.

compensation 1 

When you wish different compensation amount depending on the 
direction 

When SV042 (OVS2) is "0", compensate with the value of SV031 
(OVS1) in both of the + and -directions. 

If you wish to change the compensation amount depending on the 
command direction, set this and SV042 (OVS2).  (SV031: + direction, 
SV042: - direction.  However, the directions may be opposite 
depending on other settings.) 
When “-1” is set, the compensation won’t be performed in the 
direction of the command.

SV042 OVS2  Overshooting 

compensation 2 

Set this with SV031 (OVS1) only when you wish to set the overshooting 
compensation amount to be different depending on the command 
directions. Set to “0” as a standard.

Set the non-sensitive band of the overshooting compensation type 3 in
increments of 2µm at a time. 
In the feed forward control, the non-sensitive band of the model position
droop is set, and overshooting of the model is ignored.  
Set the same value as the standard SV040.

1.  When either parameter SV031 (OVS1) or SV042 (OVS2) is set to 0, the same 

amount of compensation is carried out in both the positive and negative 
direction.  

2.  To compensate in only one direction, set -1 in the parameter (OVS1 or OVS2) 

for the direction in which compensation is prohibited.  

3.  For contour cutting, the projection at the arc end point is compensated with 

OVS compensation. LMC compensation is carried out at the arc starting 
point.
