[Data type] Word
[Valid data range] 1 to 32767
When an arbitrary gear ratio is used in rigid tapping, each of these
parameters sets the number of teeth of each position coder gear.
NOTE
1 These parameters are enabled when the VGR parameter
(bit 1 of parameter No.5200) is set to 1.
When a position coder is attached to the spindle, set the
same value for all of parameters No.5231 through No.5234.
When a spindle motor with a built–in position coder is used,
a position coder with a resolution of 2048 pulses/rev may be
used. In such a case, set the actual number of teeth,
multiplied by 2 (for conversion to 4096 pulses/rev).
2 When the DMR function of the position coder signal is used
with a serial spindle, set the VGR parameter (bit 1 of
parameter No.5200) to 0, and set these parameters to 0.
3 When rigid tapping is performed using the second and third
spindles
• When the SPR parameter (bit 1 of parameter No.5204)
is set to 0, the settings of parameters No.5231 and
No.5232 are applied to the second spindle, as well as to
the first spindle.
• When the SPR parameter (bit 1 of parameter No.5204)
is set to 1, the settings of parameters No.5235 and
No.5236 are applied to the second spindle.
