- 304 -
4811
Allowable error count for the error pulses between two spindles in the serial
spindle synchronous control mode or simple synchronous control mode
[Data type] Word
[Unit of data] Pulse
[Valid data range] 0 to 32767
Set the allowable error count for the error pulses between two spindles
in the serial spindle synchronous control mode or simple synchronous
control mode.
NOTE
This parameter is used to output the inter-spindle
phase error detection signal SYCAL in the serial
spindle synchronous control mode. The SYCAL
<F044#4> signal becomes "1" when a phase error
exceeding the value set in this parameter is found.
When you are going to use this parameter to detect
error pulses during simple synchronous control,
pay attention to the mode of the spindle, and set
the parameter as required. (The parameter is
invalid in spindle mode. It is valid in Cs contour
control, rigid tapping, and spindle positioning mode;
the detection unit per pulse differs, however.)
Master spindle in spindle synchronous control
4812
Slave spindle in spindle synchronous control
4813
[Data type] Byte
[Valid data range] 0, 1 to number of spindles or m × 10+n (m: 1 to number of paths, n: 1
to number of spindles)
Set a master spindle/slave spindle in spindle synchronous control.
[Setting value] 1 to 4 : First to fourth serial spindle of the local path
11 to 14 : First to fourth serial spindle of path 1
21 to 24 : First to fourth serial spindle of path 2
31 to 34 : First to fourth serial spindle of path 3
NOTE
These parameters are valid only under spindle
synchronous control by CNC program. If spindle
synchronous control ON (G51.8) is specified by
programming when 0 is set, an alarm is issued.
