2. FUNCTION EXPLANATION
FANUC AC SPINDLE MOTOR a series
93
[Machining system (M series)]
Each gear time constant becomes valid by setting the
parameter below.
0077 #1
0 : the same time constant for all gear
1 : each time constant for each gear
By setting the following parameter, the different time
constant between the cutting in and cutting out (extracting)
becomes available.
0035 #5
0 : The same time constant between cutting in and out.
1 : The different time constant between cutting in and out.
As an summary, refer to the table belows.

[Turning system (T/TT series) ]
Set the parameters as below according to the gear selection
signal.
Fst. sp : GR2, GR1
Snd. sp : GR21 (Multi–spindle control option is needed)
By setting the following parameter, the different time
constant between the cutting in and cutting out (extracting)
becomes available.
0029 #3
0 : The same time constant between cutting in and out.
(NO. 415 to 418)
1 : The different time constant between cutting in and out.
Cutting in : NO. 415 to 418
Cutting out : NO. 419 to 422
