NON-CONTACT OUTPUT OR S5-DIGIT ANALOG
OUTPUT (Cent’d)
Gesr selection output (GRL, GRH) and Gear selection input (GRA,
GRB) select four types of gear range.
20.2.45 SPINDLE SPEED OVERRIDE (SPA, SPB,
SPC, SPD, SPE) INPUTS
These inputs are used, in the case of the S5-digit analog command
or non-contact output, to override the S command in a range of
50% to 120% at the execution of the part program in the automatic
operation mode.

20.2.43 GEAR SHIFT ON (GST) INPUT AND SPIN-
DLE ORIENTATION (SOR) INPUT
These inputs are used to make the S5-digit command analog output
and non-contact output provide the outputs other than the part
program S command. When GST input is closed, the voltage set by
parameter #6270 is outputted.
If SOR input is closed, the spindle speed set to parameter #6275
by the spindle gear range input and spindle motor speed command
voltage corresponding to each gear are outputted.

Notes :
1. It is possible to make the analog output corresponding to GST, SOR
inputs negative by the S5-digit analog output invert (SINV) input.
2. The period of time betweent the setting of GST and SOR inputs and
the catching-upof the analog voltage value is shorter than 100ms.
20.2.44 SINDLE SPEED REACHED (SAGR) INPUT
This input is used to inform, in the case of the S4-digit command,
that the spindle speed has reached the specified value at the start of
cutting at the execution of the part program in the automatic
operation mode. At the start of cutting (when switching from a
positioning command to a cutting command takes place), the
control delays the time by the value specified in parameter #6224,
make sure that SAGR input is closed, and starts cutting.
To perform the operation by SAGR input described above, set
parameter #6006 D4 to” 1.“
If it is set to “O,” SAGR input is ignored.
