The higher order 8bits and lower order 8bits are used for different functions.

time compensa-
tion
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 generated.

Current bias 1 Set to “0” as a standard.
Use this in combination with SV040 and the high
order 8bits of SV045.
0 to 127
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.

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.
