3701 SS2 ISI
[Data type] Bit
ISI Specifieds whether the serial spindle interface is used.
0 : Used
1 : Not used
NOTE
1 This parameter is enabled only when the serial spindle
interface option is provided. The parameter is used when
the CNC is started after serial spindle interface control is
temporarily disabled during startup adjustment of the CNC.
This bit should normally set to be 0.
2 When Serial spindle is used with Analog spindle and this
parameter is set to “1”, Analog spindle becomes 1st spindle.
SS2 The number of connections in serial spindle control
0 : 1
1 : 2
NOTE
To connect two serial spindles, set jumper S1 on the 1st
serial spindle control unit to B.
(For S series SERIAL SPINDLE AMPLIFIER)
No. 4000 to 4351: S1 → For 1st serieal spindle
S2 → For 2nd serial spindle
The above parameters are on the CNC, but actually they are used for the
spindle control unit of serial spindle.
