II - 72
【#2254】 SV054 ORE Overrun detection width in closed loop control
Set the overrun detection width in the full-closed loop control.
When the gap between the motor side encoder and the linear scale (machine side encoder)
exceeds the value set by this parameter, it will be judged as overrun and "Alarm 43" will be
detected.
When "-1" is set, if the differential velocity between the motor side encoder and the machine
side encoder exceeds the 30% of the maximum motor speed, it will be judged as overrun
and "Alarm 43" will be detected.
When "0" is set, overrun will be detected with a 2mm width.
For linear servo/direct-drive motor system
Not used. Set to "0".
---Setting range---
-1 to 32767 (mm)
However, when SV084/bitD=1, the setting range is from -1 to 32767 (μm).
【#2255】 SV055 EMGx Max. gate off delay time after emergency stop
Set the time required between an emergency stop and forced READY OFF.
Set the maximum value "+ 100ms" of the SV056 setting value of the servo drive unit
electrified by the same power supply unit.
When executing the vertical axis drop prevention, the gate off will be delayed for the length
of time set at SV048 even when SV055's is smaller than that of SV048.
Related parameters: SV048, SV056
---Setting range---
0 to 20000 (ms)
【#2256】 SV056 EMGt Deceleration time constant at emergency stop
Set the time constant used for the deceleration control at emergency stop.
Set the time required to stop from rapid traverse rate (rapid).
The standard setting value is EMGt≤G0tL×0.9.
However, note that the standard setting value differs from the above-mentioned value when
the setting value of "#2003:smgst Acceleration and deceleration modes bit 3-0:Rapid
traverse acceleration/deceleration type" is 8 or F. Refer to Instruction Manual of the drive
unit (section "Deceleration Control") for details.
Related parameters: SV048, SV055
---Setting range---
0 to 20000 (ms)
【#2257】 SV057 SHGC SHG control gain
When performing the SHG control, set to SV003(PGN1)×6.
When not using the SHG control, set to "0".
When using the OMR-FF control, set to "0".
Related parameters: SV003, SV004
---Setting range---
0 to 1200 (rad/s)
【#2258】 SV058 SHGCsp SHG control gain in spindle synchronous control
When using SHG control during spindle synchronization control (synchronous tapping and
synchronous control with spindle C-axis), set this parameter with SV049 (PGN1sp) and
SV050 (PGN2sp).
Make sure to set the value 6 times that of SV049.
When not using the SHG control, set to "0".
---Setting range---
0 to 1200 (rad/s)
【#2259】 SV059 TCNV Collision detection torque estimated gain
Set the torque estimated gain when using the collision detection function.
The standard setting value is the same as the load inertia ratio (SV037 setting value)
including motor inertia.
Set to "0" when not using the collision detection function.
Related parameters: SV032, SV035/bitF-8, SV037, SV045, SV060
<<Drive monitor load inertia ratio display>>
Set SV035/bitF=1 and imbalance torque and friction torque to both SV032 and SV045, and
then repeat acceleration/deceleration for several times.
---Setting range---
For general motor: 0 to 5000 (%)
For linear motor: 0 to 5000 (kg)
【#2260】 SV060 TLMT Collision detection level
When using the collision detection function, set the collision detection level at the G0
feeding.
When "0" is set, none of the collision detection function will work.
Related parameters: SV032, SV035/bitF-8, SV037, SV045, SV059
---Setting range---
0 to 999 (Stall current %)
