Parameters with an asterisk * in the abbreviation, such as PC1*, are validated with the NC power turned ON again.
3. Setup
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.
Set the unbalance torque of vertical axis and inclined axis.
