*1 Supported for the M series only. These parameters are disabled,
however, when the constant surface speed control option is used.
*2 When the constant surface speed control option is used with the M
series, the same parameter numbers as for the T series (No. 0540 to No.
0543) are used.
(2) Outline of spindle speed command processing for Series 0-C
In both the T and M series, actual output is not performed until the
direction of rotation is determined by the parameters (No. 13#7 and
13#6 TCW CWM) or by the PMC signals(SSIN, SSGN) and the M03
or M04 command.
If SSIN is 1, the direction of rotation is determined from SSGN. If
SSIN is 0 and parameters TCW and CWM are set so as to determine
the direction of rotation by M03 or M04, actual output is not
performed unless M03 or M04 is specified even once after the NC
power is turned on.
If plus or minus setting is made, instead of M03 and M04, actual
output is performed only by an S code. In this case, it is not necessary
to specify M03 or M04.
(a) T series (lathe)
(i) Sxxxxx is specified in min
-1
by the program or with the MDI.
(ii) Speed command data is calculated using the maximum
spindle speed (4096 min
-1
) set in a parameter selected
according to the gear selection signal (one of four: GR1 and
GR2 combinations at input signal).
Set spindle speed command offset compensation parameter
