MDS-D-SVJ3/SPJ3 Series Instruction Manual
5-4 Spindle control signal
(5) Spindle control input 5
bitB. Minimum excitation rate 2 changeover request (PY2)
[1] When PY2=1 is set, the minimum excitation rate 2 (SP015) is selected.
[2] When PY2=0 is set, the minimum excitation rate 1(SP014) is selected.
bitC. Speed gain set 2 changeover request (VG2)
[1] When VG2=1 is set, the gain parameter (SP008/SP009/SP010) used in the speed loop is
selected.
[2] When VG2=0 is set, the gain parameter (SP005/SP006/SP007) used in the speed loop is
selected.
[3] The speed gain set changeover is valid during the in-position.
bitD. Zero point re-detection request (ORC)
When ORC is changed from 0 to 1, the Z phase passed will be 0 (control output2/bit0).
bitE. Spindle holding force up (TLUP)
Spindle holding force up (disturbance observer) starts at TLUP=1 and that state is retained during
TLUP=1.
(Note) The bits other than those above are used for maintenance.
(6) Spindle control input 6
This is used for maintenance.
