Adjust Control Constants
Adjust Virtual Stop Position Offset (C3-13)
S Perform adjustment so that final run-on is not delayed, and there is no
overshoot.
Offset large
Stop position
S If the load inertia changes, the characteristics will also change, so check
the characteristics for the H, M, and L gears individually.
H Gear Selection
Adjust Proportional Gain (C3-02)
S If the ORE signal is not output close to the stop position, increase the
gain.
S If the shaft load is unsteady even if the ORE signal is output, reduce the
gain.
Check M Gear Selection
S Interface input status (U1-09)
Lit when M gear is selected
Adjust Proportional Gain (C3-03)
S If the ORE signal is not output close to the stop position, increase the
gain.
S If the shaft load is unsteady even if the ORE signal is output, reduce the
gain.
