The spindle motor speeds and servo motor speed of each axis are
monitored and motor speed detection signals are output to the Y address
specified in this parameter and (Y address +1) to indicate whether speeds
exceed the values set in the parameters.
WARNING
1 Be sure to specify a Y address that is not used with a PMC
sequence program (ladder).
2 When controlling two path lathe, ensure that the same value
is not set for path 1 and path 2. (Set a separate address
for path 1 and path 2 and take care they do not overlap.)
NOTE
The motor speed detection signals are inactivate whenever
the servo/spindle motor speed detection function is not
used, whenever the value 0 or a value beyond the allowable
data range is specified in this parameter, or an input/output
address specified within the allowable data range
represents an address where no I/O device is mounted.

S1 : for First spindle / S2 : for Second spindle / S3 : for Third spindle
This parameter sets the serial spindle motor speed at which the motor
speed detection signal is output. The speeds of the serial spindle motors
for the first, second, and third spindles are monitored, and the motor speed
detection signal, indicating whether the speed of each spindle exceeds the
value set in this parameter, is output to the Y address specified with
parameter No. 1891.
WARNING
For this parameter, set a motor speed rather than a spindle
speed.
NOTE
The motor speed detection signals are inactivate whenever
the servo/spindle motor speed detection function is not
used, or whenever 0 is set for this parameter.
