8. Setup
Set "the motor inertia + motor axis conversion load inertia" in respect to the
motor inertia.
Jl+Jm
SV037(JL) = *100
Jm
Set the vibration frequency to suppress if machine vibration occurs.
(Valid at 36 or more) When not using, set to "0".
Set this when the lost motion compensation timing doest not match.
Adjust by increasing the value by 10 at a time.
Set the non-sensitive band of the lost motion compensation in the feed
forward control.
When "0" is set, the actual value that is set is 2µm. Adjust by increasing by
1µm at a time.
Set this with SV016 (LMC1) only when you wish to set the lost motion
compensation amount to be different depending on the command directions.
Set to "0" as a standard.
Set this with SV031 (OVS1) only when you wish to set the overshooting
compensation amount to be different depending on the command directions.
Set to "0" as a standard.
Set the disturbance observer filter band.
Set to "100" as a standard.
To use the disturbance observer, also set SV037 (JL) and SV044 (OBS2).
When not using, set to "0".
Set the disturbance observer gain. The standard setting is "100" to "300".
To use the disturbance observer, also set SV037 (JL) and SV043 (OBS1).
When not using, set to "0".
Not used. Set to "0".
Set the vibration frequency to suppress if machine vibration occurs.
(Valid at 36 or more) When not using, set to "0".
Set the inductive voltage compensation gain. Set to "100" as a standard.
If the current FB peak exceeds the current command peak, lower the gain.
Input a length of time to prevent the vertical axis from dropping by delaying
Ready OFF until the brake works when the emergency stop occurs.
Increase the setting by 100msec at a time and set the value where the axis
does not drop.
Set the position loop gain during the spindle synchronous control
(synchronous tapping, synchronous control with spindle/C axis).
Set the same value as the value of the spindle parameter, position loop gain
in synchronous control.
When performing the SHG control, set this with SV050 (PGN2sp) and
SV058 (SHGCsp).
Set this with SV049 (PGN1sp) and SV058 (SHGCsp) if you wish to perform
the SHG control in the spindle synchronous control (synchronous tapping,
synchronous control with spindle/C axis).
When not performing the SHG control, set to "0".
Set the control time constant in dual feed back.
When "0" is set, the actual value that is set is 1ms.
The higher the time constant is, the closer it gets to the semi-closed control,
so the limit of the position loop gain is raised.
Set the dead zone in the dual feedback control.
Set to "0" as a standard.
Set the excessive error detection width when servo ON in a special control
(initial absolute position setting, stopper control, etc.).
If "0" is set, excessive error detection won't be performed.
Set the overrun detection width in the full-closed loop control.
If the gap between the motor side detector and the linear scale (machine
side detector) exceeds the value set by this parameter, it is judged to be
overrun and Alarm 43 will be detected.
When "-1" is set, the alarm detection won't be performed. When "0" is set,
overrun is detected with a 2mm width.
Set the time from when emergency stop is input to when READY is forcibly
turned OFF.
Normally, set the same value as SV056.
When using vertical axis drop prevention control, the gate off will be delayed
by the time set in SV048 even if SV055 is smaller than SV048.
