7. Servo Parameters
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.
Set to "0" as a standard.
Use this in combination with SV040 and the high order
8bits of SV045.
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.
