WARNING
Be sure to specify a Y address that is not used with a PMC
sequence program (ladder).
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.
4345 Serial spindle motor detection speed
[Data type] Word
[Unit of data] min
–1
[Valid data range] 0 to 32767
S1 : for First spindle / S2 : for Second 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 and second 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.
NOTE
1 Spindle motor speed detection is enabled only for serial
spindles.
2 The relationship between servo motor speed detection
signals DSV1 to DSV4 and the servo motors depends on
the servo axis number (servo connector number) set in
parameter No. 1023.
