【#2286】 SV086 LMCc Lost motion compensation 3 viscous coefficient
Set the machine system's viscous coefficient when selecting lost motion compensation type
3.
When not using, set to "0".
Related parameters: SV016, SV041, SV082/bit2,1, SV086
---Setting range---
0 to 32767 (0.01%•s/mm)
【#2287】 SV087 FHz4 Notch filter frequency 4
Set the vibration frequency to suppress when machine vibration occurs.
(Normally, do not set 80 or less.)
Set to "0" when not using.
Related parameters: SV083/bit3-1, SV115
---Setting range---
0 to 2250 (Hz)
【#2288】 SV088 FHz5 Notch filter frequency 5
Set the vibration frequency to suppress when machine vibration occurs.
(Normally, do not set 80 or less.)
Set to "0" when not using.
Related parameters: SV083/bit7-5, SV115
---Setting range---
0 to 2250 (Hz)
【#2289】 SV089
Not used. Set to "0".
【#2290】 SV090
Not used. Set to "0".
【#2291】 SV091 LMC4G Lost motion compensation 4 gain
Use this with LMC compensation type 3. As the delay in path tracking is monitored and
compensated, the delay in path tracking will be minimized even if machine friction amount
changes by aging. Use the lost motion compensation amount (SV016) * 5 (10% of the
dynamic friction torque) as the target. The higher the setting value is, the more accurate the
quadrant change be; however, the more likely vibrations occur.
---Setting range---
0 to 20000 (Stall current 0.01%)
【#2292】 SV092
Not used. Set to "0".
【#2293】 SV093
Not used. Set to "0".
【#2294】 SV094 MPV Magnetic pole position error detection speed
The magnetic pole position detection function monitors the command speed and motor
speed at the position command stop and detects the magnetic pole position error alarm
(3E) if any. Set the error detection level for the command speed and motor speed at the
position command stop.
Be aware when setting the parameter as the setting units for general motors and linear
motors are different.
<<For general motor>>
When the command speed error detection level is set to "0", the magnetic pole position
error (3E) is detected at 10r/min.
Set "10" as standard.
This detects the magnetic pole position error (3E) when the motor rotation speed is 100r/
min and more.
<<For linear motor>>
When the command motor speed level is set to "0", the magnetic pole position error (3E) is
detected at 1mm/s.
Set "10" as standard.
This detects the magnetic pole position error (3E) when the motor speed is 10mm/s and
more.
