(b) Gear selection signals indicating the gear state that allows
gear–dependent parameter selection (GR1, GR2, GR21, GR10,
GR20, GR30)
(c) Signal for activating a spindle motor (Forward spindle rotation
signal: SFR)
NOTE
1 With the analog interface spindle, the TLML signal is
entered for rigid tapping. With the α series and αC series
spindles, however, set the TLML signal to 0.
2 For details of the signals, refer to the CNC connection
manual.
(3) Gear Switch Signals for FS16 and FS0
With FS16 and FS0, two methods of gear switching are supported.
(a) T–type gear switching (T/TT series, or M series with the constant
surface speed option)
With this method, parameters used internally by the CNC are
switched according to the GR1 and GR2 signals (GR21 when the
second spindle is used) sent from the PMC to the CNC.
(b) M–type gear switching (standard M series)
With this method, the CNC determines the number of gear stages
from the CNC parameter setting and specified S value, and the
parameters used internally by the CNC are switched. Moreover,
the number of gear stages to be switched is sent from the CNC
to the PMC with the GR10, GR20, and GR30 signals.
For details, refer to the description of S the function in the
connection manual for each CNC. For details of the parameters,
refer to the operator’s manual.
The table below lists the parameters related to the gear switch
signals.
