Setting range
(Unit)
Set this if overshooting occurs during positioning. This compensates the
motor torque during positioning.
This is valid only when the overshooting compensation SV027 (SSF1/ovs)
is selected.
Type 1: When SV027 (SSF1)/ bitB, A (ovs)=01
Set the compensation amount based on the motor’s stall current.
This compensates overshooting that occurs during pulse feeding.
Normally, use Type 2.
Type 2: When SV027 (SSF1)/ bitB, A (ovs)=10
Set the compensation amount based on the motor’s stall current.
Increase by 1% and determine the amount that overshooting doesn’t
occur.
In Type 2, compensation during the feed forward control during circular
cutting won’t be performed.
Type 3: When SV027 (SSF1)/ bitB, A (ovs)=11
Use this to perform the overshooting compensation during circular
cutting or the feed forward control. The setting method is the same in
Type 2.

Overshooting
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.
