【#2231】 SV031 OVS1 Overshooting compensation 1
This compensates the motor torque when overshooting occurs during positioning. This is valid only
when the overshooting compensation (SV027/bitB,A) is selected.
Type 3 SV027/bitB,A=11
Set the compensation amount based on the motor stall current. Observing positioning droop
waveform, increase in increments of 1% and find the value where overshooting does not occur.
To vary compensation amount depending on the direction.
When SV042 (OVS2) is "0", change the SV031 (OVS1) value in both of the +/- directions to
compensate.
To vary 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 will not be performed in the direction of the command.
Related parameters: SV027/bitB,A, SV034/bitF-C, SV042, SV082/bit2
---Setting range---
-1 to 100 (Stall current %)
Note that the range will be "-1 - 10000" (Stall current 0.01%) when SV082/bit2 is "1".
【#2232】 SV032 TOF Torque offset
Set the unbalance torque on vertical axis and inclined axis.
When the vertical axis pull up function is enabled, the pull up compensation direction is determined
by this parameter's sign. When set to "0", the vertical axis pull up will not be executed.
This can be used for speed loop delay compensation and collision detection function.
To use load inertia estimation function (drive monitor display), set this parameter, friction torque
(SV045) and load inertia display enabling flag(SV035/bitF).
Related parameters: SV007, SV033/bitE, SV059
---Setting range---
-100 to 100 (Stall current %)
