When 100% is set, the voltage equivalent to the logical
non-energized time will be compensated.
Adjust in increments of 10% from the default value 100%.
If increased too much, vibration or vibration noise may be
generated.
When not using, set to "0".
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)/ bit11, 10 (ovs)=01
Set the compensation amount based on the motor's stall
(rated) current.
Increase by 1% and determine the amount that
overshooting doesn't occur.
In Type 1, compensation during the feed forward control
during circular cutting won't be performed.
Type 2: When SV027 (SSF1)/ bit11, 10 (ovs)=10
Use this if you perform the overshooting compensation
during the feed forward control during circular cutting.
The setting method is the same in Type 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.
Set the unbalance torque of vertical axis and inclined
axis.
