9. SPINDLE SPEED FUNCTION
466
When bit 7 (SRS) of parameter No. 5200 is set to 1, to select a spindle to
be used for rigid tapping, set the signals as indicated below.
Signal state
Spindle used for rigid tapping
RGTSP1 RGTSP2
First spindle “1” “1”
First spindle “1” “0”
Second spindle “0” “1”
P/S alarm No. 205 is issued. “0” “0”
WARNING
These signals must be applied before the command for rigid
tapping (M29 S....; G84 X...) is specified. The states of
these signals must not be changed before rigid tapping has
been completed.
[Classification] Input signal
[Operation] These signals are used to stop each spindle when the multi–spindle
control is used. In a PMC sequence for rigid tapping, the ENB and ENB2
signals are used. Accordingly, the logic of the signals used for a spindle
selected to perform rigid tapping must match the logic of the spindle stop
signal *SSTP.
*SSTP1 1 : The output to the first spindle does not specify 0 min
–1
.
0 : The output to the first spindle specifies 0 min
–1
.
*SSTP2 1 : The output to the second spindle does not specify 0 min
–1
.
0 : The output to the second spindle specifies 0 min
–1
.
[Classification] Input signal
[Operation] This signal is used to select the second position coder when the
multi–spindle control option is being used. Note, however, that it cannot
be used with a spindle selected to perform rigid tapping.
1 : Control is exercised using a feedback pulse signal from the second
position coder.
0 : Control is exercised using a feedback pulse signal from the first
position coder.
For rigid tapping, this signal is not used. Instead, a position loop is
constructed by combining the first spindle with the first position coder,
or by combining the second spindle with the second position coder.
