Spindle speed override signals SOV0 to SOV7<Gn030>
[Classification] Input signal
[Function] The spindle speed override signal specifies an override from 0% to 254% in
1% units for the S command sent to the CNC.
[Operation] An override value in binary must be set in 8 bits from SOV7 to SOV0.
The spindle speed override function is disabled (an override of 100%is
applied) under the following conditions:
- Tapping cycle (M series: G84, G74 T series: G84, G88)
- Thread cutting (M series: G33 T series: G32, G92, G76)
→When this function is not in use, specify an override of 100%;otherwise,
an override of 0% becomes effective, thus disabling the spindle from
rotating.
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.
