(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.
Normally use type 3 to provide compatibility with the old method.
Type 2: When SV027 (SSF1)/ bitB, A (ovs)=10
Set the compensation amount based on the motor’s stall current.
Normally use type 3 to provide compatibility with the old method..
Type 3: When SV027 (SSF1)/ bitB, A (ovs)=11
Use this to perform overshooting compensation of the standard
specifications.
Set the compensation amount based on the motor's stall current.
Increase the amount in increments of 1%, and find the amount where
overshooting does not occur. Also set SV034 (SSF3)/bit F to C (ovsn)
when using feed forward control.

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.
