B-63943EN-1/02 11.SPINDLE SPEED FUNCTION
- 1347 -
When the second, third, or fourth position coder is not installed, do
not switch this signal. Always set "0" for first position coder.
Spindle enable signals ENB<Fn001#4>,ENB2<Fn038#2>,ENB3<Fn038#3>,ENB4<Fn039#1>
[Classification] Output signal
[Function] These signals inform PMC of whether or not to perform output to the
second to fourth spindles in multi-spindle control. For the first spindle,
ENB <Fn001#4> can be used as usual. The signals are used as a
condition to stop the analog spindle, and are also used for a PMC
ladder sequence that is associated with rigid tapping. (See “RIGID
TAPPING.”)
[Output condition] ENB Enables output of command other than 0 to the first spindle
control unit.
Outputs 0 to the second spindle control unit.
ENB2 Enables output of command other than 0 to the first spindle
control unit.
Outputs 0 to the second spindle control unit.
ENB3 Enables output of command other than 0 to the third spindle
control unit.
Outputs 0 to the third spindle control unit.
ENB4 Enables output of command other than 0 to the fourth
spindle control unit.
Outputs 0 to the fourth spindle control unit.

[Classification] Input signal
[Function] The spindle motor of each spindle can be controlled by issuing
commands from the PMC.
The speed command and polarity (rotation direction) of the spindle
motor can be controlled. Usually, CNC commands are used to specify
a speed and polarity. By using these signals, whether commands
issued from the CNC or PMC are to be used for this control can be
selected.
Even when multi-spindle control is not being used, the signals can be
used to control the second to fourth spindles.
When multi-spindle control is being used, and TYPE-A is selected (bit
2 (MSI) of parameter No. 3709 is set to 0), the signals for the second
to fourth spindles cannot be used.
For details of each signal, see “SPINDLE OUTPUT CONTROL BY
THE PMC.”
