When 100% is set, the voltage equivalent to the logical
non-energized time will be compensated.
When "0" is set, a 100% compensation will be performed.
Adjust in increments of 10% from the default value 100%.
If increased too much, vibration or vibration noise may be

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
Normally use type 3 to provide compatibility with the old method.
Type 2: When SV027 (SSF1)/bitB, A (ovs)=10
Normally use type 3 to provide compatibility with the old method..
Type 3: When SV027 (SSF1)/bitB, A (ovs)=11
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.
SV031 OVS1

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.
