part program as analog or non-contact output signal for an S5-digit command.
If GRO input is “closed”, the voltage set for parameter pm1413 is output.
If SOR input is “closed”, spindle speed set for parameter pm1412 resulting from the
spindle gear range input and spindle motor speed command voltage that correspond to
the gear ranges, is output.
Setting of GRO and SOR Input Signals
Note: The status of signals is indicated by “0” or “1”.
0: Open
1: Closed
IMPORTANT!
1.It is possible to invert the voltage command (analog output for GRO, SOR input) by the
input of a S5-digit analog output inversion (SINV#31104) input signal.
2.The length of time in which an analog voltage value responds to the setting of the GRO
and SOR inputs is less than 100msec.
4.5 Spindle Speed Agreed Input Signal
If the CNC specification is a S5-digit analog command or non-contact output, this input
signal indicates that the spindle speed has reached the specified speed at the point where
cutting starts during the execution of a part program in automatic mode.
When cutting should start (axis feed mode is changed from the positioning mode to an
