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.
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.
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.
