B–63010EN/02
394
7636
Upper limit of the slave spindle speed
[Data type] Word
[Unit of data] min
–1
[Valid data range] 1 to 19999
Specify a clamp speed for the slave spindle. If the slave spindle speed
calculated from the master spindle speed exceeds the specified slave
spindle clamp speed, the actual slave spindle speed is clamped at this
clamp speed. At the same time, the master spindle speed is decreased to
maintain a constant spindle rotation ratio.
NOTE
The spindle synchronization option is needed.
It is valid when parameter SBR (bit 2 of parameter No. 7603)
= 1.
7640
Master axis in spindle–spindle polygon turning
7641
Slave axis in spindle–spindle polygon turning
[Data type] Byte
[Valid data range] 0, 1 to Number of spindles
These parameters set the master and slave axes in spindle–spindle
polygon turning.
Settings 1 : First spindle
2 : Second spindle
3 : Third spindle
4 : Fourth spindle (only for the Series 16i)
NOTE
1 Spindle–spindle polygon turning is enabled only for serial
spindles.
2 If the setting of either parameter is “0”, polygon turning is
performed for the first and second spindles.
Any spindle in another path cannot be specified.
