【#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.
---Setting range---
-1 to 100 (Stall current %)
Note that the range will be "-1 - 10000" (Stall current 0.01%) when SV082/bit2 is "1".
【#2242】 SV042 OVS2 Overshooting compensation 2
Set this with SV031 (OVS1) only when you wish to vary the overshooting compensation amount
depending on the command directions.
Normally, set to "0".
---Setting range---
-1 to 100 (Stall current %)
Note that when SV082/bit2 is "1", the setting range is between -1 and 10000 (Stall current
0.01%).
【#2227】 SV027 SSF1 Servo function 1
bit B-A : ovs Overshooting compensation
Set this if overshooting occurs during positioning.
bitB,A=
00: Compensation stop
01: Setting prohibited
10: Setting prohibited
11: Type 3
Set the compensation amount in SV031(OVS1) and SV042(OVS2).
Related parameters: SV031, SV042, SV034/bitF-C
【#2234】 SV034 SSF3 Servo function 3
bit F-C: ovsn Overshooting compensation type 3 Non-sensitive band
Set the non-sensitive band of the model position droop overshooting amount in increments of 2μm.
In the feed forward control, set the non-sensitive band of the model position droop and ignore the
overshooting of the model.
0 : 0 μm, 1: 2 μm, 2: 4μm,---, E : 28 μm, F: 30μm
